BIOPBLADE™
The sterile, single-use BIOPBLADE™ is a flexible scalpel used for cutaneous surgery,
including: shave biopsy, saucerisation of flat lesions and levelling of pedunculated lesions.
The unique design of the BIOPBLADE™ incorporates a comfortable and protective
‘Fingerguard’ in addition to the flexible super sharp blade. This flexibility allows the blade to
be positioned at the correct angle for the intended procedure.
The BIOPBLADE™ is utilised for removal of lesions, either elevated (shave biopsy) or flat
(saucerisation). After the site is anaesthetised, the BIOPBLADE™ is held and ‘bowed’
between the thumb and fingers. The lesion is removed at or just below the surface epithelium.
Cosmetic results are normally good and the wound heals without the need for suturing. The
Clinician will remove all of the lesion without overly deep penetration to avoid scarring.

Serum Calcium, Iron and Alkaline Phosphatase
Many of the range of close to 1200 tests performed by or arranged through the
Biochemistry Department have requirements which, if not recognised and met, may
lead to misleading or delayed results. The section below refers only to requirements
at the time of collection. Those tests that require pre-test preparation of the patient
are listed subsequently.
When using evacuated blood tubes (vacutainers) for sample collection, it is important to
collect biochemistry samples before haematology. If a full vacutainer is collected, a small
volume of blood usually refluxes back into the needle during withdrawal of the container.
Test Requirements at Time of Collection
BLOOD, SERUM OR PLASMA TESTS
Arterial or Venous Blood Gases
Blood remains living, actively metabolising tissue after collection and unless measures are
taken to slow or halt metabolic activity, misleading results will be obtained. It is important
that blood collected for oxygenation and pH studies should be cooled on ice or cold
packs as soon as possible (within 20 minutes) after collection or an artefactual metabolic
acidosis (low pH and bicarbonate, with raised negative base excess) may ensue from
red cell generation of lactic acid from glucose. A slower process, white cell aerobic
metabolism leading to a slow fall of pO2 and a rise of pCO2 with apparent respiratory
acidosis will further complicate interpretation.
Serum Electrolytes, Glucose, Enzymes and Phosphate
A living cell maintains a steep electrolyte gradient across the cell membrane with high
extracellular sodium and chloride, and high intracellular potassium concentrations. In
contrast, intracellular sodium and chloride and extracellular potassium concentrations
are around 5% of the corresponding transmembrane levels. The maintenance of
these gradients is an active process, requiring plentiful ATP. If blood is stored at room
temperature, glucose is consumed (metabolised to lactic acid) to maintain the membrane
gradients. This is accompanied by a fall of bicarbonate to <10 mmol/L. When the sample
glucose falls to <2 mmol/L, cellular metabolism fails and electrolyte leakage occurs.
Plasma sodium falls sequentially to as low as 80-90 mmol/L, chloride to 60-70 mmol/L,
and potassium rises to as high as 15-20 mmol/L. Lactate dehydrogenase (LD/LDH) and
aspartate transaminase (AST) escape and may elevate the plasma level to 4-5 times
the upper limit of normal. Intracellular phosphate also escapes with the shutdown of
glycolysis and may elevate the plasma phosphate to 4-5 mmol/L.
5.1
The only way to prevent this sequence of events is to centrifuge and separate the
serum/plasma from the cell mass, preferably within 20 minutes of collection into a serum
separation tube (SS tube), plain tube or other tube. The gel plug of the SS tube separates
cells from serum. With other tubes it is advisable to decant the supernatant serum/plasma
into a sterile plain tube(s) for storage. This should be stored refrigerated. Collection of the
sample into fluoride oxalate preservative or refrigeration of the sample eliminates the loss
of glucose and maintains a normal anion gap but other changes proceed.
If haematology is collected first, this blood contains the EDTA anticoagulant and can
pass into the next tube attached. If the latter is used for biochemical profile assay,
we occasionally note a small but significant fall in calcium and iron. Rarely, a marked
suppression of these as well as suppression of alkaline phosphatase may be noted. There
is concern that milder artefacts go unrecognised.
Serum Therapeutic Drugs
After administration of a drug, there is an interval between the absorption of the material
and its uptake into the tissues within which it is active, during which the serum levels are
misleadingly high (because they do not meaningfully reflect end-organ or tissue levels). This
interval is known as the distribution phase. Clearly drug levels must be examined after this
interval to give most useful information. The exception to this is seen with the antibiotics,
in which the peak level itself conveys valuable information relating to bactericidal effect
and to risk of toxicity.
PREFACE - BIOCHEMISTRY
TESTS WITH SPECIAL COLLECTION REQUIREMENTS
Blood Alcohol and other Medico-legal Collections
When blood is collected for possible legal purposes (e.g. to challenge a police breathalyser
finding), it is important to first of all obtain samples as close as possible to the time of the
initial sampling and then to adequately seal those samples so that the pathologist can
certify that no tampering has occurred between collection and testing. An appropriate
method of sealing a blood tube is the placement of one QML Pathology bar code label,
saddle-like across the top of the tube so that the ends reach approximately a centimetre
down the glass, followed by the wrapping of a second label around the body of the
tube so that it covers the ends of the first. The patient details are then completed and
the collector and patient each sign across the joint of the two labels. The protocol also
includes a Chain-of-Custody form which records the legally correct Chain-of-Custody of
the specimen from collection to production of a report. This form is to be signed by both
donor and collector. Chain-of-Custody forms detail the procedure and are available on
request from QML Pathology.
We also strongly recommend that saline or sterile water only be used to cleanse the
skin before venepuncture, and not alcohol swabs. Although isopropanol does not crossreact as ethanol in the laboratory assay, the necessity to argue this point in the court
setting can lead to the whole collection being discounted.
Plasma Lactate
Lactic acid is the end product of anaerobic metabolism and is elevated in states associated
with liver disease, ischaemia, shock and blockade of Kreb’s Citric Acid Cycle. However,
it is also the normal product of red cell glycolysis. Hence if blood is collected and allowed
to stand at room temperature, red cells will convert glucose to lactate and produce a
spurious lactic acidosis (with lowered glucose and bicarbonate, and a raised anion gap
and lactate). Examination of the results reveals a pattern that is indistinguishable from a
5.2
PREFACE - BIOCHEMISTRY
PREFACE - biochemistry
true pathological lactic acidosis. To guard against this, it is necessary to centrifuge the
blood within 20 minutes of collection and separate the cells from the plasma/serum. A
serum separation tube (SS tube) allows this without decanting the serum. Alternatively,
collection into a fluoride oxalate preservative tube inhibits metabolism such that physical
separation may be deferred until the sample reaches the laboratory. Cooling the sample to
refrigerator temperature also partially achieves this end but at the expense of meaningful
electrolytes (see previous page).
Plasma Very Long Chain Fatty Acids and Phytanic Acid
VLCFA are performed in the diagnosis of adreno-leucodystrophy, Refsum’s Disease,
Zellweger’s Syndrome and related abnormalities of cellular peroxisomal function. Phytanic
acid is relatively more specific to Zellweger’s Syndrome. Both of these tests are referred
to Royal Brisbane Hospital for analysis. In all laboratory analyses, some clinical details are
valuable in case extra testing or additional tests are indicated. However, with these tests
the referral laboratory will not commence the analyses unless adequate clinical details are
supplied with the sample. So as to avoid undue delay, please write appropriate clinical
details on the request form.
Neonatal Screen (Heel Skin-Prick Blood)
In Queensland, the routine neonatal screen includes tests for phenylketonuria,
hypothyroidism, galactosaemia and cystic fibrosis. The tests are routinely performed on
paper discs punched from a standard filter paper card. Assume even application of the
infant’s blood onto marked areas of the card. Uneven application, particularly reapplication
onto areas previously dried may lead to falsely high results and hence potential risks of
false alarms for all of the tests. If a card is not available, blood may be collected into an
EDTA or Lithium heparin tube and the application to the card made in the laboratory
before transfer to the screening laboratory.
Plasma Ammonia
Ammonia cannot be meaningfully assayed on skin-prick blood because the high sweat
ammonia level always leads to marked false elevation of the apparent blood level from
contamination.
Trace and Toxic Elements from Skin-Prick Blood
Rigorous attention to skin cleansing is always essential before collection as contamination
from material on the surface of the skin can produce marked elevation.
URINE TESTS
Urinary Porphobilinogen (PBG)
Urinary Catecholamines and VMA
Epinephrine (adrenaline), norepinephrine (noradrenaline), dopamine and their metabolites
vanillylmandelic acid (VMA, 4-hydroxy-3-methoxymandelic acid, HMMA), and
homovanillic acid (HVA) are the key elements in the diagnosis of phaeochromocytoma
and childhood neuroblastoma and ganglioneuroma. The metanephrines have declined in
popularity with improvements in the former assays. Current assays are not susceptible to
interference from dietary vanillin. However, mild pathophysiological elevation of excretion
in response to illness, injury, psychiatric agitation and to fluctuations in blood pressure is
common. Particularly difficult are the often marked elevations of excretion in response
to commencement or dose increases of antihypertensive therapy; increases which
may persist for 1 - 2 weeks while a new steady state is achieved. In the case of newly
diagnosed or suddenly deteriorating hypertension, the ideal would be to collect a single
24 hour urine sample before changing therapy. Plasma catecholamines are available but
their diagnostic value as a screen is not as clear (because of rapid elevation before or
during venepuncture). Dihydroxyphenylglycol assay is also available but again this is not
as attractive as a first line test because it has a turnaround time of several weeks.
PREFACE - BIOCHEMISTRY
PREFACE - BIOCHEMISTRY
PREFACE - biochemistry
24 hour urinary catecholamines must be collected into acid preservative (or if collected
as a stat or random collection, the sample must be kept refrigerated until acidified in the
laboratory). Please refer to the specific test in the A-Z listing for full collection details.
Urinary Drug Screen for Overdose
Please notify the laboratory and seal samples as described under ‘blood alcohol
and other medico-legal collections’ (5.2) if foul play or potentially lethal toxicity is suspected.
Clearly, there may be medico-legal implications.
Urine Drug Screen for Industry, Occupational and Drugs of Abuse
This test is probably the one most likely to give misleading results as a direct result of
deliberate interference with the collection by the patient. Substitution with urine from
another, dilution with tap or toilet water or saliva, oral water loading to dilute urine,
consumption of other substances in an attempt to mask drug findings and addition of
chemicals to the urine to attempt to breakdown urinary drug metabolites are common
occurrences among the group of patients who find themselves required to undergo this
testing. Supervision of the collection and sealing of the sample is essential. The
QML Pathology protocol complies with Australian/New Zealand Standard AS/NZS4308.
The protocol includes a specifically designed tamper-evident urine specimen bottle, a
procedure designed to ensure collection of a truly representative sample of urine from
an identified patient, and documentation that is signed by the donor and collector and
that records the legally correct Chain-of-Custody of the specimen from collection to
production of a report. Chain-of-Custody forms detail the procedure and are available on
request from QML Pathology. Please refer to the Biochemistry Appendix (12.13) for a full
list of drugs assayed.
5.4
5.3
A raised PBG excretion in a stat urine collection taken during a symptomatic episode is a
key finding in the diagnosis of an acute porphyria (Acute Intermittent Porphyria, Hereditary
Coproporphyria, or Variegate Porphyria). However, PBG is quite unstable and the sample
must be refrigerated and protected from light (wrapped in foil or brown paper), as well as
tested as soon as possible after collection.
CSF TESTS
NOTE: Faeces has a proportionally huge bacterial load and their continuing
metabolism may significantly alter the faecal biochemical profile.
Cerebrospinal Fluid Protein
WITH ALL biochemical faecal tests, it is essential that the sample be refrigerated or
frozen as soon as possible after collection.
Faecal Analysis for Reducing Substances and Sugar Chromatography
When testing for sugar/lactose intolerance, it is advisable to ascertain that the child has
not commenced a lactose-free diet. Parents have been known to commence treatment
before firm diagnosis, and this will certainly produce a false negative (normal) result.
NOTE: It is the fluid component of the faeces specimen that is required for testing. Use
of a non-absorbing liner such as ‘Glad Wrap’ to prevent absorption by the baby’s nappy
when collecting a specimen is advised.
Faecal Fat Analysis
Refrigerated sample storage is very important (see above). Fly larvae (maggots), an
occasional finding in the laboratory, may both consume malabsorbed triglyceride and
produce their own. Nappy liners must not be used during collection. The patient must be
taking an adequate diet not excluding fat or a falsely normal test will result.
Faecal Porphyrin Excretion
In addition to standard sample-handling procedures, it is essential that the patient should
avoid contamination of the collection with urine. The high urinary uroporphyrin and
coproporphyrin will falsely elevate the total and mask the characteristic faecal pattern.
Faecal Alpha-1-Antitrypsin Analysis
Alpha-1-antitrypsin is used as the marker of choice for the detection of enteric proteinlosing states, not because of any unique handling of this protein but simply because it is
relatively resistant to bacterial degradation. However, the sample must be refrigerated as
soon as possible after collection.
Faecal Pancreatic Elastase-1 (PE1)
5.5
The faecal elastase-1 concentration reflects the secretory capacity of the pancreas. That
is, the diagnosis or exclusion of pancreatic exocrine insufficiency. The concentration of
PE1 may be lowered in very watery stool samples. Formed stool samples are the preferred
sample. Samples should be frozen ASAP.
Rarely, we receive CSF which has been contaminated with myelogram contrast material.
This results in a false elevation of the assayed protein level which may be marked (e.g.
up to 20 g/L {R.R 0.4 g/L}). If there is any suspicion of this, the situation can be rapidly
clarified with CSF albumin assay.
SWEAT TESTS
Sweat Electrolytes
Only under exceptional circumstances will the clinician collect sweat samples. We strongly
support this - the collection is too difficult unless performed by trained and experienced
staff. However, should a collection be unavoidable, it is essential that any evaporative loss
must be avoided as it leads to false elevation of electrolytes and, potentially, misdiagnosis
of Cystic Fibrosis.
PREFACE - BIOCHEMISTRY
FAECES TESTS
SALIVA TESTS
Salivary Screen for Drugs of Abuse
This test requires 10 mL of saliva in a sterile screw top (urine) container. Collection must
be supervised as described for urine.
HAIR AND/OR NAILS TESTS
Hair or Nail Analysis for Toxic Elements
Hair or nails must be thoroughly cleaned without shampoo, soap or detergents before
collection. Because maximal deposition takes place in the keratin being laid down while
the metal level is maximal in soft tissue, nail can detect exposure 4 to 8 months previously
and hair 2 to 6 months previously (depending on the length).
Quantity of material for analysis:
Hair - A packed matchbox
Nail - As much as possible from fingers and toes. Clearly, if exposure is very recent,
i.e. of the order of weeks, blood or urine testing may be more appropriate.
STOMACH CONTENTS/VOMITUS TESTS
Vomitus Analysis for Drugs in Suspected Overdose
In addition to standard requirements of refrigeration to stabilise the sample both chemically
and microbiologically, it is essential that any suspicions of possible exposure should be
noted on the request form. This is to expedite testing the more likely drug classes. If there
is any possibility of medico-legal implications, this should be noted on the request form
and the sample should be sealed as described for blood alcohol.

BREAST MILK TESTS
Breast Milk Analysis for Nutritional Qualities
In cases of maternal concern, we occasionally test breast milk for glucose, lactose, lipid
and protein content. Because the sample is invariably contaminated during collection, it
must be refrigerated promptly until arrival at the laboratory.
DETECTION AND IDENTIFICATION OF SNAKE VENOM
IN SUSPECTED SNAKE BITE
The most appropriate and preferred sample for testing is snake venom from the site of
the bite. Moisten a cotton swab or cotton bud with saline or tap water and swab the site
of the puncture wound(s). A small piece of clothing cut from the bite site may also be
taken if appropriate. The swab(s) and the cloth sample should be placed in a labelled dry
sterile screw top container (microurine container) - one sample per jar. Please contact the
laboratory and forward the specimen as soon as possible.

Urine collected in a sterile screw top container and blood collected in a Lithium Heparin
tube may also be tested, however, the swab and/or cloth from the bite site(s) are the
preferred samples.
The service is available on an urgent basis 24 hours per day.
TESTS REQUIRING PRE-TEST PATIENT PREPARATION
• Breath hydrogen analysis
(general fasting instructions and no smoking one hour prior to test)
• Cholesterol and triglycerides (may require fasting if directed by doctor)
• Glucose tolerance test
• 5-Hydroxyindoleacetic Acid (5-H.I.A.A.)
• Water deprivation test

HOMOLOGOUS BLOOD TRANSFUSION SERVICE
QML Pathology provides a Cross Match Service for elective surgery using
homologous random donor blood provided through the Australian Red Cross
Blood Service.
AUTOLOGOUS BLOOD TRANSFUSION SERVICE
QML Pathology offers an Autologous Blood Donation Program for patients desiring an
alternative to homologous random donor blood provided through the Australian Red Cross
Blood Transfusion Service. There are many recognised advantages for autologous transfusion
in selected patients undergoing elective surgical procedures, including the elimination of
serological incompatibility and transfusion acquired HIV and Hepatitis infection.
Requests for autologous transfusion should be written on the special QML Pathology
form and be accompanied by request forms for:
1. Serology for Syphilis, Hepatitis B and C, HTLV-1 and HIV
2. Hb, Antibody Screen and Cross Match.
Pre-printed request forms for collection of autologous donations by QML Pathology
and the patient information brochure ‘Autologous Blood Donations’ are available
on request from QML Pathology Collection Centres, QML Pathology Brisbane Liaison
Services (07) 3121 4943 or your local Branch Laboratory.
For further details please contact QML Pathology Blood Bank (07) 3876 8371 or your
local Branch Laboratory.

PREFACE - blood bank
Patients who are excluded by the Red Cross guidelines may be acceptable for autologous
blood collection by QML Pathology. The referring practitioner must indicate that in his/her
opinion the patient’s physical condition will permit venesections to be performed safely. It
is emphasised that initiation of the collection request should allow sufficient time for clinical
review, an achievable collection plan for the desired number of autologous donations and
coordination of iron supplement therapy where directed by the QML Pathologist.
If autologous blood collection is desired, the following important information should
be noted:
1. Prior to venesection it is requested that basic testing (full blood count, blood group and
antibody screen) be performed to ensure there is no haematological contraindication
to the procedure. All autologous units collected will be screened for Syphilis,
Hepatitis B and C, HTLV-1 and HIV by QML Pathology. This is in accordance with
the recommendations by NATA/RCPA Accreditation Authority and the Australian New
Zealand Society for Blood Transfusion. Referring doctors should advise their patients
accordingly.
2. Blood donations are collected into CPD-Adenine anticoagulant and have a shelf life
of approximately 35 days. Donations are collected at weekly intervals for a maximum
of four donations, and preferably no venesections are performed in the week prior to
surgery. The expected fall in haemoglobin for an average adult male is approximately
10 gm per litre per donation (the fall will be somewhat greater in females). A check
haemoglobin is therefore performed prior to each venesection. Patients are usually
placed on an oral iron supplementation (Ferrous Sulphate - 350 mg -1 tablet twice daily
prior to their procedure) by the QML Pathologist.
5.10
5.9
3. On admission to hospital, a specimen is collected for Cross Match and Antibody
Screening. Although the patient is to receive autologous blood it is essential for safety
and medico-legal reasons (clerical errors, etc.) that compatibility tests be performed.
Secondly, the autologous collection procedure is only performed on the proviso that
if additional blood is required beyond the autologous reserve the patient will accept
homologous (Red Cross) blood. Should this prove necessary the laboratory will have
a stored cross match specimen available and there will be no additional fee applicable
for cross matching the homologous blood.
SPECIMEN COLLECTION FOR GYNAECOLOGICAL CYTOLOGY
Most cervical cancers and precancers arise in the transformation zone – that is, where
everted endocervical epithelium comes to be replaced by metaplastic squamous
epithelium. Therefore, it is crucial that this area is well visualised and adequately sampled.
The location of the transformation zone may vary depending on a woman’s age and
menstrual history.
The use of the modified Ayre’s spatula or Cervex sampler is adequate in most instances.
A cytobrush may be used when the transformation zone is located further up the
endocervical canal, as is the case in post-menopausal women.
Preparation
• If collecting a biopsy specimen at the same time, it is important to keep histology
specimens and cytology slides physically separated during storage and transport.
Liquid formalin vapour has an adverse effect on Pap smears which can make
morphological assessment difficult.
Spatula & Cytobrush
Cervex Sampler
PREFACE - CYTOLOGY
PREFACE - CYTOLOGY
PREFACE - cytology
• Label frosted-ended glass slides with the patient’s name and date of birth using
a pencil.
• Complete the request form including the patient’s name, date of birth, date of last
menstrual period and other relevant clinical information e.g. pregnant, post natal, post
menopausal, use of hormones, presence of IUD.
• Record any high risk factors including prior treatment for CIN, abnormal cervical
appearance, presence of contact or post coital bleeding.
• Check whether the patient wishes her name to be withheld from the Pap Smear
Register. If there is no indication on the form the result details will automatically be sent
to the register.
Collection
• After introduction of a vaginal speculum and proper visualisation of the cervix, gently
rotate the spatula 360˚ about its axis to ensure sampling of the entire transformation
zone. If a Cervex sampler is used, rotate through 360˚, three times in both clockwise
and anticlockwise directions. Press the outer bristles of the brush firmly against
the ectocervix.
• If using a cytobrush in conjunction with the spatula, perform this sampling after an
ectocervix specimen has been collected to avoid contamination by blood. Avoid
inserting the cytobrush too far into the os, in order to minimise sampling of the lower
uterine segment. Some bristles should still be visible. Rotate the brush twice (180˚).
• It is advisable not to use the cytobrush if the patient is pregnant.
Preparing and Fixing the Sample onto the Slide
• Transfer the sample onto the slide using a painting action, with just enough pressure to
ensure cell transfer. This is best achieved by smearing the spatula or Cervex sampler,
or by rolling the brush.
• Fix the smear quickly to prevent air drying by spraying with Cytospray at a distance of
15-20cm from the slide. Alternatively immerse the slide immediately in 95% ethanol for
15 minutes.
5.12
5.11
• Leave the slide to dry for 15 minutes and place into the plastic slide carrier provided.
Place the carrier along with the patient request form into a plastic specimen bag.
ThinPrep Specimens and HPV Testing
Pap Smear Collection Kits
• The ThinPrep Imaging System utilises cells
harvested from the collection device by rinsing into
a preservative fluid.
QML Pathology supplies various collection kits for cervical smears which are conveniently
packaged to suit different clinical indications.
• HPV DNA Testing for high risk HPV types can also
be performed from the ThinPrep vial.
• It is desirable when collecting a liquid-based sample
to use either a cervex sampler or a plastic spatula.
A wooden spatula is not recommended as cells
tend to stick to the wood and are not easily released
into solution.
Single Use Pap Smear Kits:
May be left overnight at room temperature after fixing. These kits are suitable for
conventional Pap smears and ThinPrep.

• Prepare the conventional slide and rinse the
device(s) in the PreservCyt solution. Push the
Cervex brush into the bottom of the vial and twirl
vigorously to ensure as much cellular material as
possible is released in the solution.
• Discard the collection device after rinsing.
• Replace the PreservCyt cap and tighten so that the
small black mark passes the corresponding line on
the vial.
• Label the vial with the patient name and date of
birth, and place into the plastic specimen bag
along with the conventional smear and completed

Nipple Discharge
Effusions and Washings
• Label slide/s with a pencil.
• Collect in a sterile dry container of appropriate size.
• Gently squeeze the nipple until fluid appears.
• The entire effusion specimen should be submitted.
• Smear the fluid directly onto the glass slide.
• Label the specimen container and send to the laboratory as soon as possible or
• Fix the slide immediately.
• Refrigerate if a delay in sending the specimen is anticipated (Do not add any fixative).
• Allow slides to dry.
• If Lymphoma is suspected then immediate transportation to the laboratory should
be arranged.
• Send to the laboratory - in a slide carrier with the request form.
Fluids
Sputum
• Consider requesting fluid protein examination.
Transudates have a protein content of <3.0 g/dL and a specific gravity of <1.015.
Exudates have higher protein and specific gravity, and are more likely to be inflammatory
or neoplastic.
• Collect deep cough early morning specimens preferably on three consecutive
days. Instruct the patient to collect specimens before breakfast preferably after rinsing
out the mouth.
FINE NEEDLE ASPIRATION CYTOLOGY
• Collect each specimen in a sterile container. Use one container for each collection.
Scope for Use
• Label the specimen container and send each one to the laboratory as soon as possible
or
• Refrigerate if a delay in sending the specimen is anticipated.
Fine needle aspiration (FNA) is a branch of diagnostic cytology that interprets changes in
cells extracted from within organs, tumours and non-neoplastic abnormal tissues.
Note: Please specify X 3 sputum collection on consecutive days on request form.
Urine
• Urine may be collected as a random specimen or as a series of three specimens
preferably on consecutive days.
• Collect the first part, or all (not mid stream) of the second or later void of the day.
The first void contains cells which have been sitting in urine for hours and will show
degenerative changes.
• Collect the urine in a sterile container.
• Label the specimen container and send it to the laboratory as soon as possible or
• Refrigerate if a delay in sending the specimen is anticipated (Do not add any fixative).
Note: Please specify X 3 urine collection on consecutive days on request form.
Cerebrospinal Fluid - CSF
• Collect the CSF in a sterile dry container.
• Label the specimen container, mark the request form as urgent and send to the
laboratory as soon as possible or
• Refrigerate if a delay in sending the specimen is anticipated (Do not add any fixative).

PREFACE - CYTOLOGY
PREFACE - cytology
FNA contrasts with exfoliative cytology, which studies cells shed or scraped from surface
epithelia or mesothelia. The diagnostic criteria of both branches have many common
features as well as many important differences.
Just as FNA is an extension of morphologic diagnosis within both diagnostic cytology
and histology, it is also a useful tool for the oncologist who deals with undiagnosed
palpable and non palpable masses and lesions. It is a short cut to direct diagnosis and
can be carried out at the surgery, clinic or bedside. It may also obviate the need for
radiographic and surgical procedures, and save time, expenses and morbidity, and
allay anxiety.
The common targets currently being aspirated are thyroid, liver, breast and lung. Multiple
sites of cyst formation are easily aspirated. These include breast, thyroid gland, parotid
gland, branchial cysts and cavitating squamous cell carcinoma. Aspiration of cysts can
be both diagnostic and therapeutic.
Basic Equipment
• Syringe pistol (now commercially available - but not essential).
• 10/20 mL disposable plastic syringe - can be used without a syringe pistol.
Apply negative pressure by pulling on the piston in the usual way.
• Plastic extension tubing.
• Fine needles of 25-20 gauge varying from 1cm to 20cm in length (23 gauge needles are
used for most aspirations of palpable lumps).
5.16
5.15
• Alcohol prep sponges.
• Sterile gauze pads.
• Microscope glass slides with frosted ends (label with pencil).
• Suitable spray fixative (Cytofix) or a coplin jar of 95% ethyl alcohol, to hold glass slides
for immediate fixation of wet smears.

Diagram A
• 2 mL jars of sterile normal saline.
Syringe pistol
• Transport cylinders for recapped, secured, labelled needles and syringes.
NOTE: QML Pathology can supply the necessary equipment and materials contained in
a handy rigid transport cylinder kit on request (illustrated in Collection Materials Section
(4.13) of this Manual).
A small plastic tray easily holds all the equipment as well as longer needles measuring
15cm and 20cm, employed for transthoracic and transabdominal aspirations. Local
anaesthesia, 1% or 2% lignocaine (Xylocaine), may be required for needle aspiration
of transthoracic or transabdominal masses, but it is rarely necessary for other clinically
palpable lumps. Since FNA is virtually non-traumatic, it may be repeated frequently
enough to procure adequate amounts of material for diagnostic purposes.

Method (3) (no syringe - using needle only - repeatedly rapidly inserted into and withdrawn
from the lesion inducing cells into the bore of the needle by capillary action) is preferred
in many centres but is not appropriate for cysts and has not, in our hands, produced
consistently good material.
• Thoroughly palpate the target area and delineate the most suspicious, usually the most
firm portion

• Fix the mass with the palpating hand

• Prepare the skin with an alcohol swab, alcoholic chlorhexidine or povidone iodine
• Introduce the needle into the mass.
In the case of the vacuum assisted technique:
• Application of full vacuum to the syringe with needle in the mass
• One smear should be immediately fixed (in 95% ethyl alcohol or spray fixed), the
other allowed to air dry.
• Continuously apply full suction to the aspirating syringe while the needle is moved
back and forth with short quick strokes and in slightly different directions. (The variation
in needle direction has been greatly exaggerated in the illustration.) This alteration
in direction should be fairly minimal in practice, and, coupled with the forward and
backward motion, is carried out within the mass
NOTE: It is very important when using spray fixatives to avoid holding the can closer than
15cm from the slide.
• Cease aspiration when material enters the transparent hub of the needle
Residual material always remains in the needle after smear preparation. On the other
hand it may not always be possible or desirable to prepare a smear in the clinic or at the
bedside. This material may be preserved and transported as outlined below.
• Release suction before withdrawing the needle, and then apply pressure to the puncture
site with the patient’s or nurse’s assistance.
Place labelled smears in slide carriers for transport to laboratory.
2. Preservation of Aspirated Material
In the case of the needle-only technique:
i. Syringes and Needles
• Rapidly and repeatedly insert the needle into and withdraw it from the lesion inducing
the cells into the bore of the needle by capillary action
Syringes and needles used in preparation of smears should not be discarded following
preparation of smears. Rinse material remaining in needle and syringe into a labelled
2 mL jar containing normal saline and send to laboratory where cells will be retrieved by
centrifugation and/or filter techniques. The syringe and needle may now be discarded.
• Cease when material is seen to enter the hub of the needle and slowly and gently withdraw
• To make smear preparations, attach a syringe - with the plunger drawn back a few mL
- to the needle and proceed as outlined below.
HANDLING OF SPECIMENS
1. Preparation of Smears
Making the smear is critical because it determines the quality of the material the
microscopist will examine. In practical terms, it may be the most important manoeuvre in
the whole range of steps in the aspiration.
• Rapidly separate the needle containing the aspirated material from the syringe and draw
a few mL of air into the syringe.
• Reattach the needle to the syringe.
• Express the material onto a glass slide, generally forming a drop or droplets with small
particles of tissue. Care must be taken to place the bevel of the needle against the slide
so there are no intervening air gaps allowing the material to splatter across the slide.
• Place a second glass slide on top and pull both slides rapidly apart
(see diagram above right).
• Two slides (smears) are thus prepared from each drop.

PREFACE - CYTOLOGY
For all of these techniques, the basic procedure is as follows:
ii. Fluid or Bloody Aspirates
Where specimens are diluted by fluid or blood, or for specimens which are largely
fluid e.g. cyst fluid obtained from breast or thyroid, immediate despatch of the carefully
recapped, labelled needle and syringe with contents to the laboratory is recommended.
The cap should be secured, syringe labelled and placed in a transport cylinder. This
should be forwarded to the laboratory in an insulated container with ice brick as soon as
possible. Standard cytologic filter and centrifuged preparations can then be prepared in
the laboratory. Rinsings are preferable.
Transport of FNA to the Laboratory
• Preparation of smears and rinsing of syringe and needle into saline as described above
in ‘handling of specimens’.
• Labelled smears should be placed into slide carriers.
• Store the labelled saline specimens in a refrigerator (crisper bin area).
• Transport specimen to laboratory in a rigid transport cylinder, placed in a cooled
(ice brick) insulated container as soon as possible.
NOTE: QML Pathology can supply the necessary equipment and materials on request.

Substances measured include:
• Hormones
• Tumour markers
• Special proteins.
The specific laboratory tests performed by the Endocrinology Department are listed
alphabetically in the A-Z test listing (6.0) of this Reference Manual. This listing will include
alternative names for tests, instructions for collection including the specified container,
storage and transport, any special requirements and an indication of turnaround time
of results.
Note: Slow freezing of Renin specimens by placing in a standard freezer without
the snap freezing procedure will cause falsely high values as Renin is activated by
cold temperatures.
Reporting Time
This varies from same day - 24 hours for the majority of assays (e.g. thyroid function
studies, pregnancy-related tests) - to days and weeks for less commonly required assays
(e.g. aldosterone). These are specified for the individual tests in the A-Z list (6.0).
SPECIMEN COLLECTION
FERTILITY TESTING AND CYCLE TRACKING
In general serum from clotted blood is the preferred specimen (SS tube - yellow top
tube). Usually 1 mL of blood is adequate per test. After collection the specimen should
be kept cool (refrigerated) and transported to the laboratory in an insulated container with
ice bricks (except Renin which should remain at room temperature).
The object of testing is to detect when and whether ovulation is occurring or whether there
is any follicular response or an excessive follicular response to any follicular stimulation
protocols being used in assisted fertility programs. The following tests are available:
Any variation from this routine collection procedure will be specified in the comment
section of the alphabetical listing for the particular test.
1. Is ovulation occurring - Weekly progesterones
2. P
recise timing of ovulation - Daily LH/Progesterone levels in late follicular phase of the
menstrual cycle
SPECIMEN PROCESSING
3. Follicular response to stimulation protocol - Oestradiol levels during stimulation
Freezing Serum
4. Investigation of possible androgen excess - LH/FSH ratio, Oestradiol and Androgens.
Due to the instability of some hormones the serum may need to be frozen prior to
transport to the laboratory. This may be particularly important for rural and remote regions
where transportation time is prolonged. This requirement will be indicated in the comment
section for any particular test. 20 minutes after collection into an SS tube (Yellow top
tube) the completely clotted specimen should be centrifuged to separate the serum
from the cells. The serum should be decanted into labelled plain 5 mL plastic screw cap
container(s). This may be frozen by placing in the freezer compartment of a refrigerator.
The frozen specimen should be transported to the nearest Branch Laboratory or directly
to the central laboratory in Brisbane in an insulated container with dry ice. If dry ice
is unavailable please contact the Branch Laboratory or Endocrinology Department
(07 3121 4439) for assistance.
If you have a requirement for this service please contact the Endocrinology Department
(07) 3121 4439 or the nearest Branch Laboratory and this can be arranged. With prior
notice results for Oestrogen, Progesterone, LH and FSH assays can be available 90
minutes after arrival of the specimen in our Brisbane Central Laboratory, and selected
Branch Laboratories.
Snap Freezing Serum
The procedures outlined above are adequate for most specimens. However, for Renin
Assay the specimen should be collected in EDTA tubes. It is then centrifuged at room
temperature; the serum decanted into labelled plain 5 mL plastic screw cap container(s)
and snap frozen within one hour of collection.
To Snap Freeze - pour alcohol (ethanol, methylated spirits, methanol) into a beaker to a
depth of 4 cm. Drop 3 or 4 small pieces of dry ice into the alcohol. The addition of the dry
5.21
ice will be accompanied by spluttering, however, it results in a rapid drop of the alcohol
temperature to the desired level. The tubes containing the separated serum are placed
upright in the alcohol (taking care not to contaminate the contents with the alcohol) and
will freeze immediately. The frozen specimens can then be transferred to and stored
within the freezing compartment of a standard refrigerator. The frozen specimen should
be transported in an insulated container with dry ice to the laboratory.
PREFACE - ENDOCRINOLOGY
The Endocrinology Department is located in the Brisbane Central Laboratory of QML
Pathology. The activities of this laboratory involve measurement of a range of over 30 lowlevel concentration substances using sensitive Immunoassay technologies.
HELICOBACTER PYLORI CARBON-14 UREA BREATH TEST
This test involves ingestion of low dose carbon-14 labelled urea and measurement of
carbon-14 labelled CO2, in expired air, released by the enzyme urease produced by
Helicobacter pylori.
It is preferred for the patient to fast before the test, but not necessary. The dose is
swallowed (-tasteless in water) and mouth is rinsed, 20 minutes later, a breath sample is
collected in a glass vial containing a CO2 trapping liquid.
The glass vial is identified by name, sealed, placed in a plastic bag and transported to the
laboratory where the activity of the trapped labelled CO2 is measured.
Please contact Brisbane QML Pathology Collection Department (07) 3121 4450 or your
local Branch Laboratory for details of collection centres equipped to perform this test.

conditions is satisfied:
1. The patient has an abnormal level of TSH
2. The tests are performed for the purpose of:
i. Monitoring thyroid disease in the patient; or
ii. If the patient is in hospital - investigating the sick euthyroid syndrome; or
iii. Investigating Dementia or psychiatric illness of the patient; or
iv. Investigating Amenorrhoea or infertility of the patient.

4. The patient is taking drugs that interfere with thyroid hormone metabolism or function
(e.g. Lithium, Amiodarone).
To assist the laboratory, when requesting thyroid function tests, please supply a
comprehensive history, including medication, so that the correct range of tests may
be performed.
Patient History
Please supply relevant clinical history, details of medication or hormone therapies and the
results of any relevant previous investigations which may have been carried out. Such
details are important in the interpretation of serum levels. Even factors such as the time
of day and stage of the menstrual cycle may be important in the interpretation of levels.
This will assist in the provision of appropriate comments on the report.
SPECIMEN STORAGE
Samples are kept within the laboratory for one week, should further testing or comparative
testing become necessary. The key to referencing the sample is the quote number printed
in the lower right hand corner of the pathology report. If this is unavailable patient name
and date of birth will suffice.
The Endocrinology Department is staffed routinely 6.00am to 1.00am Monday to

retardation in affected females. Expansions in the premutation range (55 – 230 repeats)
have been linked with disorders such as fragile X ataxia/tremor syndrome and FMR1related premature ovarian failure.
MOLECULAR GENETIC TESTING
Y Chromosome Microdeletion Analysis
The department offers a comprehensive and expanding range of molecular tests in the
areas of genetic disorders, microbiology and oncology.
The deletion of the AZF (azoospermic factor) region on the Y chromosome is thought
to be pathogenically involved in male infertility associated with azoospermia or severe
oligospermia. Microdeletions involving the DAZ gene account for approximately 6% of
infertile men classified as idiopathic oligo/azoospermia.
These tests include:
GENETIC DISORDERS:
Hereditary Haemochromatosis (HFE gene)
Hereditary haemochromatosis is an autosomal recessive disorder of iron metabolism that
results in iron overload and may be fatal if allowed to progress but well treated if detected
early. It affects approximately 1 in 200 people, and has a carrier frequency of 1 in 7 in
individuals of Northern European descent. Three missense mutations, C282Y, H63D, and
S65C have been identified in the HFE gene and are tested for by QML Pathology.
Factor V Leiden and Prothrombin G20210A Mutation Analysis
5.25
Resistance to activated protein C is the most common defect associated with an inherited
predisposition to venous thrombosis, resulting from a mutation in the Factor V gene.
Heterozygosity to this mutation is associated with an 8 fold increased risk of venous
thrombosis, whereas a homozygous patient has an 80-100 fold increased risk.
PREFACE - GENETICS
The QML Pathology Genetics Department is responsible for the molecular detection of
a number of known genetic mutations, the detection of chromosome abnormalities in
various tissues, and for the non-endocrinological aspects of fertility testing.
Sex Determining Region (Sry) Gene
The SRY gene is present on the short arm of the Y chromosome and is one of the
switches for sex determination in humans. This test is useful as a screening test in cases
of newborn babies with ambiguous genitalia.
HLA-B27 Gene Testing
HLA-B27 is a Class I antigen that is found on the surface of all nucleated cells and
platelets. It is found in 90% of patients with ankylosing spondylitis. However, it is also
present in 5-10% of a normal Caucasian population. All known B27 subtypes including
the rare B2707 and B2711 subtypes are detected by QML Pathology.
MICROBIAL TESTING:
Another common genetic variation associated with an increased risk of venous thrombosis
involves a mutation in the prothrombin gene (G20210A). The prevalence of the mutated
allele is 6% among deep venous thrombosis cases and is associated with a 3 to 4 fold
increased risk.
Clostridium Difficile Testing
Methylenetetrahydrofolate Reductase (MTHFR) Mutation
Cat Scratch Disease
Hyperhomocysteinaemia has been identified as a risk factor for coronary artery disease,
stroke and venous thromboembolic disease. A common mutation (C677T) in the MTHFR
gene has been described that renders the MTHFR protein thermolabile. Homozygosity
for the mutation may interact with environmental factors, such as folic acid deficiency, to
predispose to Hyperhomocysteinaemia.
Following a bite, scratch or lick from a cat, a person may develop swollen lymph glands,
fever and malaise. The usual causative bacterial agent of cat scratch disease, Bartonella
henselae, can be detected by PCR.
Apolipoprotein E Genotyping
Genotyping identifies alleles associated with type III hyperlipidaemia (allele 2).
Molecular analysis may be used for the sensitive detection of the four Plasmodium species.
This can be useful when parasite levels are very low, or in the detection of mixed species
infections. It can be a useful diagnostic tool when used in conjunction with routine methods.
Fragile X Syndrome (FRAXA)
ONCOLOGY:
Fragile X syndrome is the most important cause of mental retardation after Down
Syndrome and is due to a trinucleotide repeat (CCG) expansion of the FMR1 gene located
on the X chromosome. It occurs in individuals with an FMR1 full mutation (>230 repeats)
and is characterised by moderate mental retardation in affected males and mild mental
BCR-ABL RQ-PCR
Clostridium Difficile causes pseudomembranous colitis and antibiotic-associated diarrhoea.
It is also one of the most important causes of nosocomial infections. The organism has
genes that produce two toxins, A and B. These genes can be detected by PCR.
Malarial Parasite Detection Using PCR
The Philadelphia translocation and the associated BCR-ABL fusion genes are found
in approximately 95% of Chronic Myeloid Leukaemia (CML) and 20% of adult precursor

the BCR-ABL transcript has become an important tool in patient diagnosis and response
to treatment. Analysis is performed on extracted RNA and due to RNA degradation
samples must reach the Genetics Department within 24-48 hours post collection.
JAK2 Mutation Analysis
Janus Kinase 2 (JAK2) is a cytoplasmic tyrosine kinase which is essential in signal
transduction from multiple hemopoietic growth factor receptors. This mutation is one of
the first diagnostic molecular genetic abnormalities in Myeloproliferative disorders and is
present in 90-95% of patients with polycythemia vera (PV) who are more prone to have
homozygous JAK2 mutation. The mutation is also present in 50-70% of patients with
essential thrombocytosis and in 40-50% of patients with myelofibrosis.
CHROMOSOME ANALYSIS (Cytogenetics)
Cytogenetic analysis is a method for scanning a whole genome to provide information
about the number and structure of chromosomes. Analysis may be performed on
many tissue types and is an important tool in the identification of constitutional
chromosome abnormalities, the identification of haematological malignancies and in
prenatal diagnosis. Please see Genetics Appendix (12.29).
Tissue submitted for chromosome studies must reach the laboratory in a viable state.
Cells are grown in culture media until sufficient material is available for analysis. The rate at
which specimens grow is the principal factor determining the turnaround times of the tests.
CONSTITUTIONAL:
LYMPHOCYTE GENE REARRANGEMENT STUDIES:
Blood
B-cell Immunoglobulin Heavy Chain (IgH) Gene Rearrangements
Peripheral blood is the tissue of choice when investigating possible constitutional
chromosomal abnormalities in neonates, children and adults.
This test is for the IgH gene rearrangement (FR2 and FR3) and will detect greater than
80% of B-cell lymphoproliferative disorders.
Bcl-2
This test is specific for the major breakpoint region (mbr) of the IgH-bcl-2 associated
translocation [t(14;18)]. This translocation is associated with up to 85% of lymphomas with
a follicular morphology, and with approximately one third of diffuse large cell lymphomas.

PREFACE - Genetics
Skin
A skin biopsy can be performed for confirmation of mosaicism or the establishment of
a cell line for further study, e.g. Molecular DNA or biochemical testing. Samples from
children and adults may be taken by a QML Pathology doctor at one of our special test
collection centres or a Branch Laboratory.
ONCOLOGY:
Bcl-1
Bone Marrow
This test is specific for the translocation involving the Cyclin D1 gene [t(11;14)] which is
commonly associated with Mantle Cell Lymphoma (MCL).
Aspirated bone marrow is used for the investigation of haematological malignancies.
Chromosome abnormalities detected, (often specific for a particular disorder),
are acquired as part of the neoplastic process and are therefore present only in the
affected cell lines.
This test is for detecting monoclonality of T lymphocytes using primers targeted at
both beta and gamma gene rearrangements, and will detect greater than 80% of T-cell
lymphoproliferative disorders.
Other Molecular Genetic tests:
5.27
Genetic testing for a number of disorders is available throughout Australasia. See
Genetics Appendix (12.30). QML Pathology will perform sample collection and forward
the samples to the appropriate testing facility. It is important to note that many disorders
require genetic counselling prior to testing and most incur an out of pocket expense to
the patient. The Genetics Department maintains a list of tests available in Australasia
complete with costing and collection requirements. Please contact the department on
(07) 3121 4461 regarding availability of testing.
Lymph Nodes
Lymph node is the best tissue to culture for chromosome analysis when investigating
lymphomas. The sample is usually shared between several departments (Histology,
Haematology and Genetics). Refer to detailed guidelines in Histology Preface (5.35).
Unstimulated Blood
Peripheral blood may be used to detect acquired haematological malignancies (e.g. CML)
which have large numbers of precursor cells circulating in the blood.
Solid Tumours
A representative sample of tumour tissue should be selected. Areas of necrosis, adherent
fat and extraneous tissues should be aseptically dissected from the tumour tissue. It
should then be placed in antibiotic transport medium (not formalin) and forwarded,
cooled, to the Genetics Department as soon as possible.

T-cell Receptor (beta and gamma) Gene Rearrangements
PRENATAL:
ANDROLOGY
Chorionic Villus
Seminal Fluid Analysis
A chorionic villus sample (CVS), is taken by a specialist obstetrician under ultrasound
guidance from the developing placenta at around 10 to 12 weeks gestation. This tissue
can be cultured for fetal karyotype assessment.
Male fertility is assessed using seminal fluid in cases of unexplained infertility, as well as
post-vasectomy or after vasectomy reversal. The entire sample is required and must be
examined for motility within 2 hours of collection. The specimen should be kept at room
temperature (do not refrigerate).
Amniotic Fluid
The following are available on request from QML Pathology:
Amniotic fluid surrounding the developing fetus contains a small but adequate number
of viable cells of fetal origin. These can be cultured for fetal chromosome investigation at
≥14 weeks gestation.
• Printed patient instruction form, ‘Instruction to patients for the collection of seminal fluid’.
PREFACE - GENETICS
PREFACE - GENETICS
PREFACE - Genetics
• Plastic seminal fluid collection (SFC) containers (red screw cap).
The patient should follow the clear instructions on the printed form from QML Pathology.
Rapid Screening (FISH) Test for Fetal Aneuploidy
A rapid screening test for fetal aneuploidy using FISH probes specific for chromosomes 13,
18, 21, X and Y is available with results usually reported within 24 hours. It is recommended
that any abnormal results obtained by FISH are confirmed by full chromosome analysis
prior to any therapeutic intervention.
Products of Conception/IUFD
Chromosome abnormalities are found in >50% of spontaneous miscarriages occurring in
the first trimester of pregnancy. Cytogenetic analysis of tissue obtained from products of
conception is useful in investigating the cause of recurrent miscarriage/IUFD and in the
identification of chromosome abnormalities which may potentially pose problems in future
pregnancy attempts.
Aborted tissue should be placed in a sterile container, preferably in antibiotic transport
medium (or, if unavailable, in sterile normal saline), and forwarded, cooled, to the Genetics
Department or Branch Laboratory as soon as possible. The material required for cell
culture will be isolated by the laboratory staff and the remainder of the material will be
submitted for histological examination.
Note: The membranes and placental specimens may be the only viable tissue of fetal
origin available for cell culture. If available, fetal skin is also cultured but there may be
limited success if the fetus is autolysed.
Note: The patient should contact his nearest QML Pathology collection centre to establish
the best time to take the sample so the transit time is kept to a minimum.
Seminal Fluid Fructose
Fructose is used as a source of energy by spermatozoa, and may be depleted if the transit
time to the laboratory for examination is extended or in the presence of polyzoospermia.
Low fructose levels may be associated with low motility.
The sample is collected in the same way as for seminal fluid analysis and the test may be
performed at the same time, on the same sample. Regional or Branch Laboratories
that perform seminal fluid analysis, on completion should forward the remainder of
the specimen to the Brisbane Genetics Department for seminal fluid fructose assay.
The specimen must be frozen or transported on ice.
Antisperm Antibodies (Indirect Immunobead Test - IBT)
Antisperm antibodies may be present in either the male or female. Their presence may
reduce sperm motility and/or interfere with sperm penetration of the ovum. This test is
recommended as part of a comprehensive fertility screen of couples.
Samples required are:
Female - 10 mL clotted blood sample (SS tube).
MOLECULAR CYTOGENETICS
Male - 10 mL clotted blood sample (SS tube) and/or seminal fluid.
FISH Analysis
The antisperm antibody test is performed on an irregular basis, usually every two weeks,
depending on batch size and the availability of a normal semen sample that is used as a
substrate in the tests. Results are released on the day of testing.
FISH (Fluorescent in situ hybridisation) is a technique that allows the hybridisation of a
fluorescent DNA probe to a specific region on a specific chromosome. It is selectively used
in conjunction with conventional chromosome analysis for a wide range of applications in
prenatal diagnosis, constitutional studies and in oncology.

Leucocyte Reference Ranges
• Please supply relevant patient and clinical information with each specimen.
• Please indicate special requirements where appropriate e.g. tissue for microbial
culture, special stains, cell marker studies, immunofluorescence, electron microscopy,
suspicious or doubtful surgical margins, etc.
• Please ensure all specimens are accurately labelled.
• Where appropriate, specimen orientation should be indicated by the use of suture(s)
or clearly indicated incisions or nicks placed on the tissue specimen together with an
accompanying diagram and/or written explanation. In turn a diagram illustrating how
the specimen was processed and, where appropriate, location of involved margins, etc.
should accompany the pathology report.
•A
dvance notice of elective frozen section, pending cell tumour marker studies, skeletal
muscle biopsy, cilial biopsy or renal biopsy is required.
Routine Specimens
Specimens for routine histologic examination should be placed in 10% buffered formalin.
Optimally the specimen should be placed in 10 times the volume of formalin to the volume of the
specimen. Pre-labelled containers of all sizes are available from QML Pathology on request.
Non-Routine Specimens
Certain specimens and investigations require different or additional processing.
Tissue for Bacterial, Fungal and Viral Culture
Tissue suspected of being infected is a better source of a positive culture than a
swab. If possible a portion of the infected tissue should be placed into a dry sterile
container, without additives, for the purpose of culture. This should be forwarded to the
laboratory with appropriate clinical history (including history of antibiotic therapy) as soon
as possible. If transport delay is anticipated (e.g. overnight, rural area, etc.) the tissue
may be placed in Stuart’s transport medium. It is important to prevent dehydration of
the tissue. If transport medium is unavailable add a few drops of sterile saline to the dry
tissue container. The remainder of the material may be placed in buffered formalin and
submitted in the usual way.
Cell Tumour Marker Studies
Lymphoma
Lymph nodes and tissues infiltrated by lymphoma (e.g. skin, gastrointestinal mucosa,
etc.) and fluids heavily infiltrated by lymphoma (e.g. pleural fluid, ascitic fluid and CSF)
may be submitted for cell marker studies.
5.35
1. Lymph nodes: In the metropolitan area if the lymph node can be sent directly to the
laboratory without delay, it may be placed dry in a dry sterile, screw top (urine) container
and sent immediately to Histology (07) 3121 4426 or to the nearest Branch Laboratory
where it will be aseptically divided and shared appropriately.
In the non-metropolitan region and rural areas, and in the metropolitan area where
delays greater than 2 hours may be expected (e.g. after hours, distance and
transportation, etc.) the lymph node must not be placed in a dry container. Lymphocytes
die soon after loss of blood supply resulting in inability to culture the tissue and to detect
markers with the flow cytometer. Also autolysis occurs rapidly and there is loss of crucial
cytomorphological detail in histology. Under these circumstances the lymph node should
be transected and half the lymph node placed in antibiotic transport medium. If unavailable,
normal saline may be used as a substitute. Overnight the antibiotic transport medium
should be stored in the bottom (crisper bin area) of a refrigerator. The specimen should be
transported to the laboratory as soon as possible in a cooled insulated container.
Note: The ice brick should be separated from the tissue by packing material to
prevent freezing.
PREFACE - Histology
REQUEST REQUIREMENTS
The other half of the lymph node should be utilised for the production of touch imprints
from the cut surface on two glass slides labelled with the patient’s name and date of
birth. This is performed by gently grasping the capsular side of the lymph node with
clean forceps and gently touching with a perpendicular motion the cut surface on each
clean glass slide. It is essential not to use a lateral smearing motion. One of these slides
is allowed to AIR DRY. The other slide is fixed by spraying with cytospray. Following this,
the lymph node tissue should be immersed in formalin. If the lymph node(s) is/are very
large they should be transected further into several thinner slices before being immersed
in formalin to ensure adequate fixation of the entire specimen.
These procedures will ensure preservation of tissue viability and morphological detail both
of which are essential in the diagnosis and classification of lymphoma.
2. Tissues from other body sites which are suspected of being infiltrated by lymphoma
should be treated in a similar way.
3. Fluids such as pleural fluid, ascitic fluid and CSF should be placed in a sterile container,
without additives, kept cool and submitted to the laboratory as soon as possible.
Peripheral Blood and Bone Marrow
Cell marker studies on peripheral blood and bone marrow are useful in the identification of:
• Acute leukaemias
• Chronic leukaemias
• Malignant lymphomas
• Myeloma.
The specimens (peripheral blood and bone marrow aspirate) may be collected in Lithium
heparin tubes (green top and black top) and should be forwarded cooled to the laboratory
as soon as possible with full clinical history and details of previous tests.
Note: The cell surface marker studies are carried out on a flow cytometer in the
Brisbane Central Laboratory. Tissue from country regions should be forwarded cooled to
the nearest Branch Laboratory, which in turn will forward the specimen to the Brisbane
Central Laboratory for processing.

First Trimester Abortions
All the aborted tissue should be placed in sterile antibiotic transport medium (or, if
unavailable, in sterile normal saline), refrigerated, and forwarded cooled to the Genetics
Department (07) 3121 4461 or Branch Laboratory as soon as possible. The material
required for cell culture will be isolated by the laboratory staff and the remainder of the
material will be submitted for histological examination.
Second Trimester Abortions and Still Births
Please collect sterile samples of fetal skin from the back, and membranes and chorionic
villi from the placenta and place in sterile antibiotic transport medium (or if unavailable,
in sterile normal saline), refrigerate, and forward cooled to the laboratory as soon as
possible. The remainder of the tissue may be placed in buffered formalin. However,
if there is an intact fetus, the fetus should be kept refrigerated and discussed with a
supervising pathologist as to what further actions and/or investigations are required.
A fetus/stillbirth which is to undergo a subsequent autopsy (with parental consent required)
must NOT be placed into formalin.
These simple procedures will ensure an optimum pathology report. Where appropriate an
orientating diagram will accompany the report.
Disaccharidase Estimation on Small Intestinal Mucosa
Small intestinal mucosal biopsy tissue for estimation of disaccharidase activity should
be collected before the histology specimen as contact with formalin on biopsy forceps
(even formalin vapour) will partially or totally destroy enzyme activity. The tissue should be
wrapped in aluminium foil, placed in a labelled dry sterile screw top (urine) container and
frozen immediately after collection. It should be forwarded to the laboratory on dry ice or
packed in ice bricks, as soon as possible.
Note:
Electron Microscopy
1. If the fetus is autolysed the membranes and placental specimens are particularly
important as they may be the only viable tissue of fetal origin available for cell culture.
This may be performed on request under special circumstances. We suggest consultation
with the nearest QML Pathology laboratory prior to referral. Glutaraldehyde is available
on request. The fresh specimen should be finely diced into 1 mm cubes and placed
immediately into buffered glutaraldehyde and submitted to the laboratory.
2. Antibiotic transport medium, suitable for transportation of all viable tissues,
is available on request from QML Pathology (07) 3121 4461, (07) 3121 4502 or
Branch Laboratory. This should be stored frozen and thawed to room temperature
when required.
3. A detailed pro forma outlining requirements for chromosome analysis of fetal tissue is
available on request from QML Pathology.
Cilial Biopsy
Cilial biopsies should have motility studies performed as part of their assessment. Advance
notice (preferably a day) of the impending biopsy will enable the laboratory to prepare for
the procedure. Two specimens are ideal, one for motility studies and the other for electron
microscopy. If only one specimen is available, it must be placed into Hartmann’s buffer
which is available on request from Histology (07) 3121 4426.
If unavailable in Branch Laboratories, saline can be used. This must be submitted in a
container at room temperature to the main Histology Department without delay (within 12
hours). The specimen for electron microscopy is submitted in 3% buffered glutaraldehyde,
which is available on request.
Conjunctival/Limbal Tissue/Delicate Tissue
Thin, delicate tissue such as specimens of conjunctival and limbal lesions but also including
small skin samples from the inner canthus and mucus membranes, if placed directly in
formalin for fixation tend to become twisted and distorted, making subsequent orientation
and accurate sampling difficult or impossible. When fresh, these tissues should be placed
5.37
flat on a small piece of blotting paper with the cut surface down to ensure adhesion.
Please check the tissue is not folded over on itself and that folds and creases have been
eliminated. Now place the blotting paper with adherent tissue carefully into a container
of formalin ensuring they do not become separated. The tissue will become fixed in its
flattened state. The use of a marking suture and diagram will greatly assist the pathologist
to orientate the specimen for processing.
PREFACE - Histology
Chromosome Analysis on Products of Conception/IUFD
Frozen Section Service
Tissue for frozen section should be submitted FRESH in a DRY container (not in formalin).
Please telephone Histology (07) 3121 4426 or your Branch Laboratory for booking elective
frozen sections. QML Pathology endeavours to provide a frozen section service where
main laboratories are sited with pathologists on site – however, this does not apply to stat
laboratory locations such as Ipswich.
Immunofluorescence
Skin biopsies and renal biopsies may be submitted for immunofluorescence detection
of antibodies or antibody-antigen complexes. A detailed clinical history and provisional
diagnosis should accompany the biopsy. It is preferable to submit two separate skin
biopsies from the same lesion. If only one renal biopsy is available this can be divided
into two. One biopsy specimen should be placed in immunofluorescence transport
medium (available on request from Histology (07) 3121 4426 or your Branch Laboratory)
and the other placed in 10% buffered formalin. Before use the transport medium should
be stored refrigerated (not frozen). The specimens should be sealed and forwarded to the
laboratory for testing as soon as possible. The transport medium preserves fresh tissue
reactivity for up to 5 days at ambient temperature and provided it is correctly packaged
the specimen may be posted. If immunofluorescence transport medium is unavailable two
alternatives are available. The specimen may be snap-frozen, in liquid nitrogen, stored in
a freezer and transported frozen (dry ice) to the laboratory.

Immunoperoxidase Stains
QML Pathology tests for a wide range of cell markers with immunoperoxidase techniques.
These will be performed as required in any individual case. In most cases routine buffered
formalin fixation is adequate.
Liver Biopsy
In most cases liver biopsy tissue for histology may be submitted in buffered formalin in
the routine way. For diagnostic purposes multiple levels of the biopsy are examined using
routine H&E and a number of special stains.
Note: The specimen will be transported from Branch Laboratories to Brisbane for
processing and reporting.
Testicular Biopsy
For optimal preservation of morphology, testicular biopsy tissue taken for investigation
of infertility should be fixed in Bouin’s Fixative Solution rather than buffered formalin.
Bouin’s Fixative Solution is available on request from Histology (07) 3121 4426 or your
Branch Laboratory. Testicular biopsy for tumour diagnosis should only be performed if
orchidectomy can proceed immediately after a positive diagnosis is made (usually by
frozen section).
If you have any doubts or queries please contact the laboratory prior to surgery.
If quantitative estimation of liver iron (haemochromatosis) or liver copper (Wilson’s disease)
is required a separate biopsy should be submitted. The tissue should be wrapped in
aluminium foil, placed in a dry sterile container without additives and stored frozen. It
should be transferred to the laboratory cooled on an ice brick in an insulated container.
SKIN BIOPSIES
(Skeletal) Muscle Biopsy
Skin biopsy is a rapid procedure useful in the diagnosis of many neoplastic and inflammatory
conditions, and therefore a valuable tool when the clinical differential diagnosis encompasses
different treatment options.
All muscle biopsies should have histochemistry performed as part of the morphological
assessment. Advance notice (preferably a few days) of the impending biopsy will enable the
laboratory to prepare for the complex procedure of freezing and processing. Occasionally
electron microscopy will also be required. The muscle tissue must not be frozen and it
must not be placed in formalin prior to collection of the sample for histochemistry. An
ideal sample is a block of muscle 20mm in length by 5 to 10mm in diameter. This should
be placed in a dry sterile container without additives, cooled and sent to the laboratory
without delay (within 60 minutes). If a delay greater than 60 minutes is unavoidable then it
is preferable to refer the patient to a regional centre near the laboratory for the biopsy.
Oestrogen Receptor Assay
Oestrogen and progesterone receptor status in breast cancer can be evaluated semiquantitatively by immunohistochemical methods. This routine method of analysis is
available on formalin fixed tissue, and has replaced the previous assay requiring fresh
frozen tumour tissue.
Renal Biopsy
Renal biopsy performed for assessment of glomerular disease requires complex
processing including standard H&E and special stains on paraffin embedded tissue,
immunofluorescence techniques to demonstrate antibody or antibody-antigen complexes
and electron microscopy. Two renal biopsy cores are ideal. If only one core of tissue is
available it may need to be divided into fragments for any or all of these procedures
according to the requirements of the individual case. Such division should be carried
out by a skilled operator with the assistance of a microscope to ensure glomeruli are
5.39
present in each of the samples. Advance notice (preferably a few days) of the impending
biopsy will enable the laboratory to have available the different fixation and transport
media required and if necessary the equipment to divide the specimen.
PREFACE - Histology
Provided the specimen has been snap-frozen, preservation with this technique is excellent.
Alternatively, if transport time to the laboratory is less than four hours the specimen may
be placed on a cotton wool ball moistened with saline or in a container with only a few
drops of normal saline.
Why Biopsy?
Many skin conditions are clinically distinctive, whilst others may require histology for
specific diagnosis. At times, however, skin rashes may be both clinically and histologically
puzzling, and we may only be able to offer a range of possible diagnoses suggested by
the histology.
The value of the biopsy may be limited by its size, the site selected for sampling, superimposed
inflammatory changes, the application of topical agents, or concurrent use of medications.
One of the major limiting factors is lack of sufficient clinical information.
The histological report should be available one working day after the specimen is
collected, although urgent results may be obtained within six hours if indicated. Delays
may occur when further investigations, such as special stains, need to be performed, or
if further clinical information is required.
What Sort of Biopsy?
Incisional Biopsy
This is preferred by the pathologist as it is orientated and gives more information. It
need only be about 6mm long, 2mm wide and 4mm deep. A biopsy for deeper lesions
(including panniculitis) will obviously need to be longer and deeper. It should be orientated
radially (not tangentially) and should include about 1mm of normal skin. Distinguishing
between keratoacanthoma and squamous cell carcinoma may be very difficult on biopsy,
and only an incisional biopsy provides adequate information.
5.40
PREFACE - Histology
PREFACE - Histology
Punch Biopsy
Consider Culture
This is technically easier, but sometimes harder to interpret, as orientation in the
laboratory is more difficult. This means that sections cut from the biopsy may not be in
the optimal plane, and the lesion may be missed. For this reason it is better not to include
any normal skin in a punch biopsy. There is a preference for 3mm or 4mm punch biopsies
rather than 1mm and 2mm, as the latter options­may be inadequate.
If there is a possibility that the lesion is due to an infection, take a swab of the biopsy
wound or even send a small piece of tissue for culture (put it in a sterile jar with a small
amount of sterile normal saline and send it to the lab as soon as possible). Do not divide
a biopsy specimen.
Shave Biopsy
Important Notes for Skin Biopsies
Shave biopsies and skin currettings are usually successful in diagnosing skin tumours.
They fail when the keratin layer is deceptively thick or when the sample is too superficial.
This is particularly important in solar keratosis when invasive squamous cell carcinoma
cannot be ruled out unless the specimen includes all of the basal layer and a little
underlying dermis.
• Carefully select the biopsy site so that it is representative of the lesion or rash.
Consider more than one biopsy.
Selecting the Biopsy Site
In neoplasms, the thickest region will generally provide the most diagnostic information.
In some broad and multifocal tumours it may be necessary to biopsy several areas,
including the centre and periphery of the lesion in order to make a diagnosis.
• Mark the biopsy site prior to performing the procedure.
• Be gentle with the specimen to avoid crush artefact.
• Consider special investigations such as immunofluorescence and culture.
Send separate specimens for different tests - do not divide biopsies.
• The major role of biopsy in pigmented lesions is to confirm the clinical diagnosis of a
pigmented, nonmelanocytic lesion. If a lesion is thought to be melanocytic, and especially
if it is atypical, then narrow, but complete excision rather than biopsy is
strongly recommended.
Site selection is more critical in inflammatory rashes. It is difficult to generalise about
which lesion to biopsy, but usually the more florid the lesion clinically, the more
pathology that will be revealed. Sometimes biopsying two lesions of different ages
is helpful. Blisters and vasculitic lesions must be biopsied at an early stage as their
diagnostic features may disappear after about 24 hours.
Technical Details
Pigmented Lesions
What to Call Your Specimen
The main role of biopsy in these cases is to distinguish between melanocytic
tumours and other pigmented lesions such as seborrhoeic keratoses, solar
lentigines, basal cell carcinomas, etc. If a lesion is suspected to be melanocytic
(and especially if it is suspicious of melanoma), then complete excision with narrow
margins is strongly recommended for the purpose of diagnosis. This is because
biopsies may be misdiagnosed as either benign or malignant. In addition, if the
lesion is a melanoma, then important prognostic features may be distorted in the
re-excision specimen. Also, if a benign nevus regrows after biopsy it can develop a
pseudomalignant histological pattern, thus risking misdiagnosis of melanoma.

• Take the time to write clinical notes and a provisional diagnosis.
The pathologist performing the macroscopic
examination needs to know whether a piece of skin
this shape is an excision biopsy or an incision biopsy.
Most specimens require division before being
processed. A piece of skin this shape should be
divided this way if it is an excision specimen as these
transverse sections will display the margins of excision
in relation to a tumour.
Immunofluorescence
If, however, it is an incision specimen, it will remain
whole so that sections display the full length of the
specimen. If it is more than 3.0mm wide, it will be
divided longitudinally:
For technical reasons we reduce our tissue blocks to about 2.0mm thickness.
To avoid a good incision biopsy being partly wasted or an excision biopsy that cannot be
assessed for completeness of tumour removal, please specify excision or incision biopsy.

This study is frequently necessary for the diagnosis of blistering/bullous rashes, and
is also useful in lupus erythematosus and occasionally vasculitis. The specimen must
be submitted in an immunofluorescence transport medium which we supply from
the laboratory. It must not be placed in formalin. Because this medium is not a good
tissue fixative, we also need a biopsy submitted in formalin. It is better to take two
separate biopsies rather than divide a single biopsy. In the case of blisters, perilesional
skin should be biopsied for immunofluorescence, whilst the formalin fixed specimen
should include the edge of a fresh blister and adjacent intact skin (see above ‘Selecting
the Biopsy Site’).
Selecting the Biopsy Site
How to Biopsy
Incision Biopsy
Punch Biopsy
1. Mark the Site
Select and mark the site(s) to be biopsied. An ink marker is useful.
2. Skin Preparation
Be thorough but gentle, so that no scale or scab is rubbed off. Allow alcohol to dry
before starting a biopsy.
Blotchy, macular
3. Local Anaesthesia
1 or 2% lignocaine with 1:100 000 adrenaline is suggested.
Annular
sometimes
unsuitable for punch
NOTE: Adrenaline should not be used in certain sites.
Papular
4. Punch Biopsies
Stretch the skin between index or middle fingers, or thumb and index finger of one
hand, and press the punch in, rotating as you press until you feel it pop through
the dermis into the subcutaneous fat. Remove the punch and separate the biopsy
from the surrounding skin at the level of the fat using scissors or a scalpel blade. If
the biopsy retracts into the skin, then gentle pressure on either side of the site will
usually pop the biopsy core into view. Be gentle with the biopsy and never grasp
it with non-toothed forceps as this will crush artefact and may render the biopsy
useless. Use fine toothed forceps, a skin hook or a needle. Stretching the skin will
produce an oval rather than a round hole, and one suture will repair the site.
Vesicular, bullous
5. Incision Biopsies
Make a vertical elliptical incision about 2-3mm wide and down to fat. Try not to
undercut the edges. Grasp the biopsy by the deep edge using a skin hook or fine
single tooth forceps and free the base of the biopsy with curved scissors or scalpel
dissection. Repair with sutures.

6. Afterwards
Place the biopsy in formalin. If necessary, submit further biopsies fresh for
culture (or lymphocyte marker) or in immunofluorescence transport medium for
immunofluorescence (sent out by the laboratory on request). Label the specimen,
and please write some clinical notes on the pathology request form.
Clinical Notes
A clinical description (including clinical diagnosis or differential) is frequently useful in the
diagnosis of tumours, and is usually essential in the diagnosis of rashes. Information
should include:
• Exact site
• Size
• Duration
• Appearance
• Symptoms
• Drugs
• Clinical diagnosis.

BIOPBLADE™
The punch biopsy with internal plunger system allows the lodged skin specimen inside
the metal lumen of the punch to be easily ejected.
The sterile, single-use BIOPBLADE™ is a flexible scalpel used for cutaneous surgery,
including: shave biopsy, saucerisation of flat lesions and levelling of pedunculated lesions.
The unique design of the BIOPBLADE™ incorporates a comfortable and protective
‘Fingerguard’ in addition to the flexible super sharp blade. This flexibility allows the blade
to be positioned at the correct angle for the intended procedure.

The BIOPBLADE™ is utilised for removal of lesions,
either elevated (shave biopsy) or flat (saucerisation).
After the site is anaesthetised, the BIOPBLADE™ is
held and ‘bowed’ between the thumb and fingers.
The lesion is removed at or just below the surface
epithelium. Cosmetic results are normally good and
the wound heals without the need for suturing. The
Clinician will remove all of the lesion without overly
deep penetration to avoid scarring.

General Comments
Microbial serology is not an exact science. Problems can occur with false positive reactions
and cross reactivity. Clinicians should interpret the serological results in conjunction with
their own findings from the patient’s history and examination.
Hepatitis Serology
There are many serological tests available that are performed in the course of investigation
of clinical hepatitis or in the assessment of vaccination against either Hepatitis A or B.
• The clinical features and provisional diagnosis
To enable QML Pathology to comply with the requirements of the Medicare Schedule, it is
essential that the clinician either list the exact test required or specify the clinical condition
(e.g. resolving Hepatitis B, acute viral Hepatitis, post-vaccination, etc.) The main clinical
grouping from the Schedule are listed below for Hepatitis A, B and C:
• The date of onset of the condition
• Investigation for acute Hepatitis A (HAVIgM)
• If the patient is pregnant.
• Immune status for Hepatitis A (HAVIgG) - pre- or post-vaccination
Please refer to the Immunology Appendix (12.36) for a comprehensive list of antibodies
to microbial and parasitic agents available for testing. It is a Medicare requirement that
microbial and parasitic agents be listed individually on the request form.
• Investigation of acute or resolving Hepatitis B (HBsAg, HBcAb, HBsAb)
The laboratory relies heavily on the information provided with a request. The three most
important pieces of information required to aid with interpreting serological results are:
Antibody Profiles
The detection of microbial infection using serological methods relies on observing the
pattern of IgM and IgG responses. The first detectable response in a primary infection is
IgM which usually lasts for a few weeks to months. A few days after the IgM appears it
is usually possible to detect an IgG response, which lasts for an extended period of time
(several years) and confirms the primary infection. The presence of IgG without IgM in a
serum specimen normally reflects past exposure to the infectious agent and not acute
infection.
Although serological assays for the majority of infectious agents involve measurement
of both IgM and IgG, there are some agents for which these two assays are not yet
available. These are assayed by methods such as agglutination or complement fixation
which may not discriminate IgG from IgM.
Specimen Collection
In most instances the serum from a full SS tube (yellow top) is sufficient for all combinations
of viral, bacterial, fungal and parasitic serology. Plasma (from an EDTA or Lithium heparin
collection) is generally not suitable because of an increased tendency to give false
positive results.
Note: The laboratory stores a patient’s serum for up to 12 months to enable further tests
to be added as the clinical picture evolves, or to compare with specimens collected later
in the clinical presentation.
Microbial Serology in Pregnancy
The standard antenatal tests consist of serology for one or more of the following agents:
• Hepatitis B surface antigen
• Syphilis
• Rubella IgG
• Hepatitis C.
5.47
HIV may be added to this panel. ‘TORCH’ screening (including Toxoplasma, Rubella,
CMV and Herpes antibodies) is no longer recommended unless clinically indicated.
PREFACE - IMMUNOLOGY
Microbial Serology
• Immune status for Hepatitis B (HBsAb) - pre- or post-vaccination (Note: tests for HBsAg
and HBcAb may be indicated in some pre-vaccination screens)
• Chronic infection/carriage of Hepatitis B (HBsAg and HBeAg, but may include HBsAb,
HBcIgM, HBcAb if appropriate)
• Hepatitis C (HCV) - all clinical conditions
• Hepatitis D (HDV) - in individuals chronically infected with HBV
• Hepatitis of uncertain etiology - (HBsAg, HBcAb, HAVIgM, HCV).
There are clinical situations where other combinations of the above tests are more
appropriate - if the clinician is uncertain then please consult the Immunology Department
(07) 3121 4458 or Branch Laboratory.
Hepatitis C RNA PCR Testing
There is a Medicare rebate available under some circumstances for HCV RNA. To qualify
for this rebate, the patient must fulfil at least one of the following criteria:
• They are HCV antibody positive
• They are HCV antibody positive and immunosuppressed/immunocompromised
• They have indeterminate HCV serology
• They are being investigated for acute HCV infection prior to seroconversion.
Only 1 estimation is allowed in a 12 month period.
If the patient does not qualify by these criteria, a non-refundable fee will be charged.
If the patient does qualify, the relevant information should be supplied on the request
In addition, there is now provision for extra Hepatitis C testing in patients undergoing
specific antiviral therapy.
Quantitative HCV RNA and HCV genotype may be performed on HCV antibody positive
patients, when requested by or on behalf of a specialist physician or consultant managing
the therapy. Only a single genotype determination is allowed in a 12 month period,

Molecular Testing
The radioallergosorbent test (RAST) measures allergen-specific IgE in serum. The result
is unaffected by antihistamine or corticosteroid therapy. Whilst the term ‘RAST’ is
still reasonably used to describe these tests, the current laboratory method utilised is
immunoCAP.
QML Pathology can provide Molecular testing using the Polymerase Chain Reaction
(PCR) to assist in the diagnosis of certain infectious diseases. At present we can test for
the presence of Chlamydia trachomatis, Adenovirus, Neisseria gonorrhoeae, Neisseria
meningitidis, CMV, Hepatitis C RNA, Bordetella pertussis, Trichomonas vaginalis, Herpes
Simplex virus, Pneumocystis, Legionella, and Varicella Zoster virus, as well as testing for
HCV and HIV viral load. More tests will be added at a future date.
RAST is the method of choice for allergy testing in patients who:
Molecular testing offers highly sensitive and specific techniques for the investigation of
infectious diseases. Its value lies in its ability to detect an infectious agent that may be
present in very low numbers or cannot be cultivated. It can also assist in confirming the
presence of infection should the results of antibody detection be unclear.
• Are unable to attend for skin testing.
Prior to ordering the use of this test method, clinicians should consult the A-Z listing (6.0),
the Immunology Department (07) 3121 4458 or Branch Laboratory for details about the
collection method. It should also be noted that at present there are restrictions on the
Medicare rebate for Hepatitis C and the laboratory may charge a non-refundable fee for
some of these services.
An extensive range of single allergens, multiple allergens (e.g. grass pollen mix) and
an inhalant allergen screen are available. A full listing is provided in the Immunology
Appendix (12.37).
Tests Referred to Other Laboratories
• Medicare refunds a MAXIMUM of 4 RAST estimations in a 12 month period.
This restriction is intended to minimise indiscriminate use of RAST for screening
purposes. QML Pathology will test up to 4 allergens (single or multiple) per patient
episode. This allows up to 16 RAST estimations for the 4 allowable patient episodes
in 1 year.
In certain circumstances, e.g. when QML Pathology does not perform a test or when our
result requires confirmation by another laboratory, the patient’s serum will be forwarded
to an appropriate laboratory for testing. This results in a delay in issuing a final report.
The delay depends on the frequency of testing and the complexity of the test and in
most cases is of the order of 2-4 weeks. An interim report will be issued notifying when
a specimen is referred.
Allergy Testing
A detailed patient history is very important in the diagnosis of an allergy. Sometimes, the
history alone can pinpoint the allergen responsible for symptoms but in many cases, the
history is less revealing. However, laboratory tests should not be used as a substitute for
a good clinical history. Test results should always be interpreted in relation to the
clinical picture. Tests routinely available for the diagnosis of allergy include:
5.49
Allergen-Specific IgE in Serum (RAST)
• Have extensive skin disorders
• Have dermatographism
• Are taking antihistamines or steroids which cannot be temporarily discontinued
PREFACE - IMMUNOLOGY
and 2 quantitative RNA determinations per 12 months. However, patients undergoing
therapy may be entitled to an extra 4 qualitative RNA tests in that 12 month period
to assist in monitoring the therapy. Please contact the Immunology Department on
(07) 3121 4458 for further information.
RAST testing is the first line test for insect venom allergy and penicillin allergy, however the
sensitivity of RAST in these disorders is poor, and frequently skin allergy testing is required
for venom and drug allergy.
Please note:
• Each allergen (single or multiple) required must be specified on the request form.
A separate request form is required for each group of 4 allergens.
• Serum is stored in the Immunology Department for up to 12 months.
Skin Prick Testing
Total IgE in Serum
Skin prick testing demonstrates tissue bound specific IgE and identifies the atopic state.
It is the in vivo counterpart of RAST although the results do not always parallel each
other. Antihistamines interfere with the test and should be discontinued seven days prior
to testing. Steroid therapy may also interfere with the test. If steroid medication can be
safely ceased, this should be ceased one week before the skin test. If steroids cannot be
ceased an alternative such as RAST testing should be considered.
Healthy, non-atopic individuals have a very low amount of IgE present in the serum,
whereas in many patients with allergic disorders, IgE is significantly increased.
An extensive range of local allergens is available. A full listing is provided in the Immunology
Appendix (12.37). Allergy testing for food additives and food chemicals is not available.
High serum IgE levels are not specific for atopic diseases and can be seen in parasitic
infestations and in some immunodeficiency states. Conversely, a normal or modestly
raised serum IgE does not exclude allergy as, in some patients, a high proportion of the
total IgE present is directed against a specific allergen.
Skin testing is available by appointment at QML Pathology special test collection centres.
Please contact (07) 3121 4414 (Brisbane patients only) or your nearest QML Pathology
Branch Laboratory to arrange an appointment.

Request Form
Clinical specimens unsuitable for anaerobic culture:
The following relevant information should always accompany any request for
bacteriological examination:
• Coughed sputum
• Rectal swab
• Urine
• Swabs of superficial skin lesion
• Faeces
• Throat swab
• Ileostomy/colostomy drainage
• Urethral swab
• Nasopharyngeal swab
• Vaginal or cervical swab.
• Patient’s name and date of birth
• Date and time of specimen collection
• Site of sample and if the site is a surgical wound
• Clinical history
• Antibiotic therapy - past and present
• Please indicate if the patient is immunosuppressed/immunocompromised
• Please indicate if culture for Mycobacterium spp., fungi or unusual organisms such as
Bartonella spp. Actinomyces, Nocardia, etc. is required.
Tissue, Body Fluids and Wound Swabs –
General Principles
Please note that aspirated pus and/or tissue samples are far superior to a swab for
isolation and identification of organisms.
Tissue samples may be submitted in a dry sterile container if no delay in transportation
is anticipated. It is important to prevent dehydration of the tissue. If transportation is
delayed, add a few drops of sterile saline to the dry tissue container.
Aspirated material may be left in the syringe (carefully remove and discard the needle,
expel all air, seal with a cap and tape securely) or it may be placed in a dry sterile container,
if the specimen can be submitted to laboratory without delay.
The diagnosis of ANAEROBIC INFECTIONS is highly dependent on the correct method
of collection and handling of the sample. It is imperative that the sample is collected from
the centre of the abscess or other infected site, avoiding contamination from surrounding
tissue, as skin and mucous membranes have large numbers of anaerobes as normal
flora. Following specimen collection, samples must be transported in an environment that
is devoid of oxygen and has a low oxidation-reduction potential.
PREFACE - MICROBIOLOGY
PREFACE - MICROBIOLOGY
PREFACE - MICROBIOLOGY
Specimens aspirated by needle and syringe are ideal, provided all air is expelled.
The needle should be carefully removed and discarded. The syringe should be recapped
(held by tape), labelled and transported promptly to laboratory at ambient temperature.
Broth media can also be provided for inoculation immediately after aspiration of the
sample. If broth inoculation is carried out, a swab should also be collected.
Carefully remove needle and
discard. Recap syringe and
tape securely to syringe. Label
syringe with patient details.
If a delay is anticipated, a swab in Stuart’s transport medium should be collected in addition.
Anaerobic Culture
Clinical specimens suitable for anaerobic culture:
• Tissue biopsy
• Blood
• Bone marrow
• Fluid from a sterile site (e.g. joint)
• Material aspirated from abscesses
• Peritoneal fluid
• Suprapubic bladder aspirate
• Bronchial washings obtained with double lumen plugged catheter
• Decubitus ulcer, if obtained from the base of the ulcer after debridement of surface debris
5.51
• Transtracheal aspirate.
Swabs with bacteriology
transport medium (blue top
swab) are also suitable for
anaerobic culture but at least
two swabs must be collected.
Anaerobic infections are often
mixed infections and one swab
is used for examination of
Gram stain and aerobic culture
while the other is reserved for
anaerobic culture.
2 x Blue Top Swabs
5.52
• CSF
A series of three paired culture bottles (one aerobic, one anaerobic) is required for adults.
A series of three single culture bottles (Paediatric) is required for children.
Mycobacterial culture media are available for immunosuppressed patients.
For VERY ILL patients three sets may be taken over a period of 30 minutes (10 minutes
apart). Timing of cultures with fever peaks may be useful; however, clinical conditions may
make this impractical.
For CHRONIC ILLNESS the three cultures may be taken at intervals coinciding with fever
peaks, the periodicity of which may be quite variable (hours to days).
Venous and arterial blood are equally suitable. The bottles need to be marked so that only
the correct amount is collected (8-10 mL for adults and 1-3 mL for children). If left to fill
automatically they will continue to fill above the desired volume. The bottles also contain
a resin which eliminates antibiotics and other toxins from the cultures.
If difficulty is experienced in obtaining adequate blood volume from some patients, the
following is advised:
• One single adult aerobic bottle or one single paediatric bottle for smaller volumes.
Note: The formulation of the culture broth in the paediatric bottle optimizes bacterial
growth for small volumes (1-3 mL) of blood regardless of the source.
If several hours delay is anticipated before examination for ova, cysts and parasites, a
small amount of semi-formed stool (the size of a pea) should also be placed into OCP
(ova, cysts and parasites) transport medium.
Note: It is not necessary for a formed stool specimen to be put into OCP transport
medium, provided it arrives at the laboratory the same day as specimen collection.
Both transport media are stored at room temperature. The remaining faeces specimen
should be refrigerated until submitted to the laboratory.
Special Cases
Liquid stools - should be examined promptly. Please contact the laboratory to arrange
immediate pick up.
Amoebae - faeces for suspected amoebiasis must be examined within 30 minutes of
collection. Contact the laboratory to arrange for immediate pick up and transport of
specimen. Do not refrigerate.
Rotavirus - faeces collected for Rotavirus do not require special transport media or
precautions. The virus is only found in faeces during the acute stage of the illness. The
specimen should be refrigerated while awaiting transportation and transported cooled
to the laboratory as soon as possible.
Blood cultures should be kept at room temperature and forwarded to the laboratory for
incubation as soon as possible.
Clostridium difficile - faeces should be collected in a standard faeces container. The
specimen should be refrigerated while awaiting transportation and transported to the
laboratory within 24 hours. The specimen should be submitted for Clostridium difficile
Enterotoxin assay/PCR
Body Fluids
Nasopharyngeal Secretions
Body fluids should be collected in a labelled sterile container and capped immediately.
The specimen should be submitted to the laboratory as soon as possible. If delay is
anticipated the specimen should be stored in a refrigerator.
Nasopharyngeal secretions may be collected for viral PCR and Bordetella pertussis PCR.
Storage
Faeces
QML Pathology provides containers for the collection and transport of faeces. For infants
a piece of glad wrap may be put into a nappy to collect the sample. Specimens in toilet
paper or nappy liners are unsuitable.

a pea-sized sample of the original specimen into faeces transport medium (bacterial)
and send both containers to the laboratory.
PREFACE - MICROBIOLOGY
Blood Culture
a) For Viral PCR (Respiratory Viruses)
The method of choice for the collection of nasopharyngeal secretions, particularly from
children under five years of age is the suction technique. A fine bore catheter is passed
through the nostril, along the nasal floor to the posterior pharyngeal wall.
Ideally patients should not have received preparations containing antimicrobials, bismuth,
barium, kaolin, mineral oil, antidiarrhoeal or laxative agents during the 10 days prior
to collection.
Secretions are then aspirated by suction, e.g. by Oxyviva equipment into a trap or into
a syringe of 20 mL or 50 mL capacity attached to the end of the catheter. Secretions
should be obtained from both nostrils whenever possible and the secretions flushed from
the catheter into the trap/syringe by aspirating 2-5 mL of sterile saline. When a syringe is
used, expel the contents of the syringe into a sterile container e.g. a urine container.
In general three faeces specimens each spaced a week apart (for Medicare rebate) will
detect most parasitic infections.
Specimens should be sent to the laboratory as soon as possible and kept refrigerated
(not frozen) until tested.
Formed and Semi-formed Stools
The laboratory should receive the specimen kept at room temperature within two hours of
collection. After hours or if any further delay is anticipated when culture is required, place

Sputum should be collected in a labelled dry sterile screw cap (urine) container and
capped immediately. This should be submitted to the laboratory as soon as possible. If
delay is anticipated the specimen should be stored in a refrigerator.
Urine
After cleaning the external genitalia, a midstream voided urine should be collected by
the clean catch method into a sterile container or for babies in a paediatric bag. An
early morning collection is preferred. Other sources include catheters, cystoscopes,
suprapubic aspirates and urines from ileal conduits.
After collection aspirate the urine into the Monovette. Transport to the laboratory
immediately. If transport to the laboratory is likely to be delayed refrigerate until transport
is available. Suprapubic aspirates should be collected into a sterile container and
refrigerated if transport to the laboratory is delayed.
Urine for Mtb Culture
• Sabouraud’s dextrose fungal plate
• Enrichment broth.
These components are available on request from Microbiology (07) 3121 4438 or your
local Branch Laboratory. A variety of storage requirements and expiry dates indicate that
the components of the kit are better obtained freshly on request from the laboratory when
they are needed rather than them being stored at the surgery.
Cutaneous Fungal Culture
If superficial or deep mycoses are clinically suspected please indicate suspicion and
specify fungal culture on the request form since superficial and deep fungi are not routinely
screened for in material submitted for bacterial culture.
Deep Mycoses
If a deep mycosis is suspected a tissue biopsy offers an excellent source of material
for culture and isolation of deep fungi. Fresh tissue should be placed in a sterile dry
container, without additives, and submitted to the laboratory as soon as possible. If
transport delay is anticipated add a few drops of sterile saline to the dry tissue container
to prevent dehydration.
Superficial Mycoses
For Mycobacterial cultures collect a full 70 mL container of an early morning specimen.
Monovettes are NOT acceptable for Mtb culture.
Superficial mycoses may infect skin, hair and nails. The two most important factors
leading to a false negative mycological result are antifungal medication received by the
patient at the time of specimen collection, and a suboptimal amount of specimen.
Catheter Tips for Culture
• Antifungal medication (topical and systemic) should be ceased for at least two days,
optimally for a week, prior to collection of the specimen.
Tips from indwelling venous and arterial catheters or cannulas may be submitted for
culture purposes. Skin around the catheterized site should be disinfected prior to catheter
removal. One to two centimetres of catheter tip should be cut with sterile scissors and
dropped into a sterile container. Store at room temperature and transport to the laboratory
as soon as possible.
Ophthalmology Microbiology Kit
Material from an ocular lesion for the purposes of microbiological culture is often very
limited in quantity. In some circumstances it may be warranted to use some or all of the
components of the Ophthalmology Microbiology Kit to ensure isolation of the pathogen
or pathogens.

The kit includes the following material:
PREFACE - MICROBIOLOGY
Equipment
• Please indicate on the request form the nature of the antifungal agent and the time of
discontinuation.
• Cosmetic preparations should be ceased one to two days prior to collection of
the specimen.
Skin (tinea or ringworm)
Sterile normal saline is suitable for cleansing skin lesions from heavily contaminated sites
such as feet and sweat areas. The active edge of the skin lesion should be scraped with a
sterile scalpel blade and as many flakes and fragments as possible collected in a sterile dry
screw top container or a fungal scrapings envelope. In cases of vesicular tinea pedis, the
tops of any fresh vesicles should be removed as the fungus is often plentiful in the roof of

PREFACE - MICROBIOLOGY
Scalp
Broken diseased hair including the basal portion should be gently removed with sterile
epilation forceps. If scales are present on scalp lesions these may be collected in addition
to, but not instead of hair specimens. Specimens may be placed in a dry sterile screw top
(urine) container (a clean, sealable paper envelope will suffice).
Nail (onychomycosis)
Seventy percent (70%) alcohol is a suitable agent for cleansing nail lesions. Use a sterile
scalpel blade, scraping with the tip if necessary, to obtain the invaded nail tissue. The nail
should be pared and scraped until the crumbling white degenerating portion is reached.
Any white keratin debris beneath the free edge of the nail should also be collected.
Collected material should be placed in a dry sterile screw cap container or a fungal
scrapings envelope.
Please note:
• All collected material should be placed in clearly labelled sterile screw top containers or
fungal scrapings envelopes.
• Material from different sites should be placed in different containers (identified to site).
• For site cleansing, a gauze square is preferable to a cotton wool ball.
• If the scalpel blade used to scrape the skin is forwarded to the laboratory it must be
placed in a sterile screw top (urine) container (NOT a paper envelope).
Cutaneous Ectoparasites
Scabies
The operator should wear gloves and materials required will be a sterile scalpel blade,
paraffin oil, glass slide with frosted end labelled with patient identification (pencil) and
cover slip.
Examine the area for unexcoriated papules or for linear or wavy erythematous lines or
burrows. Having found a likely area, place a drop of paraffin oil on the scalpel blade. Apply
the scalpel blade to the papule so that the mineral oil goes onto the papule surface.
Next, scrape vigorously about six to seven times with the blade to remove the entire top
of the papule. Tiny flecks of blood should be mixed with the oil. Then, with the blade,
remove all of the oil to a glass slide. Repeat this procedure with four or five different
papules to the same glass slide. Apply the coverslip.
5.57
The slide should be clearly labelled with the patient identification. It should be placed in a
slide carrier and forwarded to the laboratory as soon as possible.
Pediculosis
The diagnosis of head and crab lice is made by finding lice or nits on the hairs. Pull out
diseased hairs with forceps and place in a sterile screw top container.
The diagnosis of body lice can be confirmed by finding lice and nits in the seams of
clothing, particularly underclothing. Samples of lice and nits may be placed in a sterile
screw top container. These containers should be clearly labelled with patient identification
and forwarded to the laboratory as soon as possible.
Demodex
Demodex folliculorum is a microscopic, cigar-shaped creature with eight stumpy legs
and an annulate abdomen. They are found in the hair follicles and sebaceous glands,
particularly on the nose and face, and probably infest over half of middle-aged adults. The
infestation is usually asymptomatic and is often noted incidentally on skin biopsies and
excisions of facial skin. Infestation may be associated with blackheads.
PREFACE - MICROBIOLOGY
the vesicle. If the lesion is exuding material and may be painful to scrape, a swab may be
collected as an alternative. Use a dry swab previously moistened with saline to swab the
lesion. Place the swab in a container without transport medium. The scalpel blade should
be included with the specimen. Place the blade in a sterile dry screw top (urine) container
NOT in a paper envelope. Please avoid sites with obvious secondary bacterial infection.
Infestation of eyelashes or hairs may be symptomatic. In order to sample it is necessary
to pull out an eyelash. This may be placed in a sterile screw top container. Alternatively, it
may be placed on a glass slide with oil, and coverslipped.
Containers should be clearly labelled with patient identification. Slides should be clearly

forwarded to the laboratory as soon as possible.
Chlamydia/Gonorrhoea PCR
Chlamydia PCR
QML Pathology has introduced an APTIMA assay for the simultaneous detection of both
Chlamydia trachomatis and Neisseria gonorrhoeae in the same sample. Both swabs and
urines are suitable samples for detection of Chlamydia with this assay. QML Pathology
supplies an APTIMA collection kit with detailed instructions on collection techniques. The
swab pack contains a white shaft swab which is a cleaning swab and a blue shaft swab
which is a collection swab. The blue shaft swab should be placed in the APTIMA tube
containing transport medium. There are no special storage conditions for these collection
kits. Chlamydia are obligatory intracellular parasites, which survive and multiply only
within living cells. For diagnostic purposes it is essential to collect infected epithelial
cells rather than mucopurulent exudate. Any purulent exudate or secretions should first
be removed with a sterile swab. Swabs for conventional bacterial cultures should be
taken prior to that for Chlamydia PCR.
In WOMEN endocervical or urethral swabs should be collected. First catch urine is also a
suitable alternative. In MEN a urethral swab OR a first catch urine sample may be collected.
Swabs from the vagina or from the penile meatus are unsuitable. If clinically indicated
throat or rectal swabs should be collected. The swab should be gently rotated and remain
inserted sufficiently long to allow adequate sampling and absorption (5 seconds within
the urethra, 20 seconds within the endocervical canal). Try to avoid touching the swab on
the vaginal wall on entry or exit.

PREFACE - MICROBIOLOGY
PREFACE - MICROBIOLOGY
First catch urine samples are the recommended urine specimen. The first 20 mL of any
voided urine collected in a sterile urine container is an acceptable alternative to a swab.
(Note: the blue Monovette containing preservative is not suitable for PCR testing.) The
patient should not have urinated for two hours prior to the test.
In the case of conjunctival, throat or rectal infection, the sampling swab should be firmly
rotated over the epithelial surface for between 10 and 20 seconds. In the case of the eye,
the lower palpebral fissure is the most suitable site to sample. In infants nasopharyngeal
swab or aspirate is appropriate. These swabs may cause some discomfort to the patient.
After collecting the sample with the swab it is placed into the white capped transport
medium tube, snapped off and the cap screwed down tightly. There are no special storage
or transport conditions for sending the specimen to the laboratory. If delay is anticipated,
urine specimens should be refrigerated and referred to the laboratory within 72 hours.
Gonorrhoea PCR
Using an APTIMA collection kit, collect swabs as per the instructions. Alternatively, a first
catch urine may be used. If culture is required, a bacterial swab should be collected and
sent in Stuart’s transport medium.
Viral Culture
Mantoux Test
The objective of the Mantoux test is to examine an immune response 48 to 72 hours after
an intradermal injection of purified protein derivative (PPD) of Mycobacterium tuberculosis
and Mycobacterium avium. The technique involves injecting 0.1 mL of a solution
containing 100 IU/mL of PPD (i.e. 10 IU per dose of 0.1 mL) using a 25 gauge needle into
the dermis. This should raise a lump in the skin 5-6 mm in diameter. The injection should
be repeated if it is too deep or if leakage occurs. The results are read 48 to 72 hours later.
The clinician should palpate the site for the presence of oedema (induration). Erythema
should be ignored. The diameter of the area of oedema measured at right angles to
the long axis of the arm is recorded.
Note: A handy card giving guidance on the performance and interpretation of the Mantoux
test is available on request from QML Pathology Liaison Department (07) 3121 4943 or
your local Branch Laboratory.
PREFACE - MICROBIOLOGY
PREFACE - MICROBIOLOGY
PREFACE - MICROBIOLOGY
Interpretation
A positive result is indicated by an area of induration 10mm or more in diameter. This
indicates previous exposure to Mycobacterium tuberculosis, atypical mycobacteria or
previous BCG vaccination. A negative result does not exclude active tuberculosis as the
reaction may be suppressed by concurrent viral infection, cancer, drug therapy or severe
bacterial infections (including tuberculosis).
QML Pathology supplies viral culture swabs and transport medium for detection of viruses
including Herpes simplex I and II, and Varicella zoster in the sample by PCR (polymerase
chain reaction - Nucleic acid detection) method. Detailed instructions on specimen
collection are supplied with each kit. The swabs should be placed on an ice brick in
an insulated container and sent to the laboratory as soon as possible. They should be
refrigerated if stored overnight. Results of the PCR are available within 24 hours.
Special Collections for Cytomegalovirus Culture
Positive CMV IgM serology under certain circumstances may require confirmation by
detection of virus by PCR (e.g. suspected antenatal or neonatal infection).
In these circumstances the specimens required include:
• Further serum sample (SS tube) PLUS
• 10 mL EDTA blood
• Saliva swab in viral culture transport medium (Virocult)
• Midstream urine in a sterile screw top (urine) container
• High vaginal swab in viral culture transport medium (Virocult) (antenatal cases only).

minutes). Transfer to the central laboratory immediately, keeping specimens at
approximately 37 degrees centigrade, using a vacuum flask or similar. Do not

1. Samples must be taken into tubes pre-warmed to 37 degrees centigrade.
2. Allow samples to stand in 37 degrees centigrade water bath for 0.5-1.0 hr to
allow separation of red cells to occur without centrifugation. If a water-bath is not
available, a container of warm water (topped-up frequently) may be used.
3. When separation has occurred, transfer serum and plasma to Falcon tubes and

Many species of microfilariae exhibit nocturnal periodicity in the blood of the host
to coincide with the biting habits of the insect vector. This periodicity appears
linked to the circadian rhythm (sleeping habit) of the host and will take about a
week to adjust to a new pattern as would occur in migration to a different time
zone. Optimum time for blood collection in an acclimatised host is 10pm to 4am.

SCREEN
Using a sterile technique, dissect the Lymph node free of adherent fat and tissue.
Slice the node into 2mm slices and place a sample in Antibiotic Transport Medium.
With the other slices, make 6 touch imprints onto glass slides, 2 of which are air
dried and 2 are fixed in 95% alcohol or Diff Quik fixative. The remaining two slides
can be forwarded to Haematology with tissue submitted for marker studies. A slice
should be fixed for 6 hours and processed overnight, while the remainder is allowed
to fix in buffered formalin for 24 hours and then placed on a 12 hour processing
cycle. Store cooled and transport cooled to laboratory as soon as possible. Please see
Histology Preface (5.35) for full details. Please contact Histology (07) 3121 4495 or
Branch Laboratory to inform of impending biopsy and for assistance.

Tumour markers, those materials whose presence qualitatively or quantitatively signal
the presence of malignancy, offer some hope in the fight against cancer. Some well
defined clinical applications include:
• The detection of malignancy
• The establishment of prognosis as an aid in differentiation
• The monitoring of treatment and the detection of a recurrence.

Diabetes mellitus
Gestational Diabetes
Carbohydrate intolerance is recognised to pose a risk during pregnancy and should be
detected if present and treated appropriately. The term gestational diabetes mellitus
applies to all degrees of carbohydrate intolerance (to include both the categories of
impaired glucose tolerance and diabetic response).
The recommendations of the Ad Hoc Working Party to the NHMRC (1991) are as follows:
Recommendations for the screening and diagnosis of glucose intolerance
in pregnancy - gestational diabetes
• All pregnant women should be screened for abnormal glucose tolerance between
26 and 28 weeks gestation. The plasma glucose level should be measured one
hour after either a 50g or a 75g glucose load given in a non-fasting state. A value
of ≥ 7.8mmol/L after a 50g load or ≥ 8.0mmol/L after 75g is regarded as positive.
Women with positive results should receive a full glucose tolerance test.
12.9
• These recommendations must not preclude confirmation of diabetes with a 75g OGTT
at any stage of pregnancy if there are clinical features to suggest the diagnosis.

The revised criteria for the diagnosis of impaired glucose tolerance and diabetes mellitus
as recommended by a Working Party of the Australian Diabetes Society, The Australasian
Association of Clinical Biochemists and the Royal College of Pathologists of Australasia
(1999) are as follows:
• The diagnosis of gestational diabetes should be made before 30 weeks gestation
by the administration in the fasting state of a 75g oral glucose tolerance test
(OGTT). A fasting plasma glucose level of ≥ 5.5mmol/L and/or a two hour plasma
glucose level of ≥ 8.0mmol/L are diagnostic of gestational diabetes.
APPENDICIES

Dietary Restrictions and Special Diets
General Fasting
On the night before the test:
• No food is to be eaten for 8 hours prior to or during the test, however the fasting
period should not be in excess of 16 hours
• Water may be consumed (recommended intake - slightly more than usual)
• No other fluid (including alcohol) may be consumed
• A record of current medication is required.
These instructions should be adhered to unless advised otherwise.
Glucose Tolerance Test
An appointment is required for this test. The patient should phone their nearest
QML Pathology collection centre to make arrangements. A list of collection centres and
phone numbers can be found on the reverse side of the request form.

For three days prior to the test the patient should have an adequate intake of
carbohydrates equivalent to the following (as a minimum) each day:
These food items are known to contain significant quantities of serotonin (a precursor of
5HIAA) and should be excluded from the diet for the three days prior to and including the day
of collection:
• 4 slices of bread, 1 plate of cereal and 2 medium potatoes. If the patient is on a
reduced, special or low-calorie diet, please inform the collection centre staff.
• Avocado
• Plum
On the night before the test
• Banana
• Tomato
• It is important for the patient to eat a normal dinner, however, not to eat, chew gum or
drink any fluids (except water) for at least 8 hours before the test. It is preferable they
do not fast for more than 12 hours.
• Coffee
• Walnuts and pecans
• Eggplant
• (Briefly - avoid fruit and nuts).
• Water may be consumed (recommended intake - slightly more than usual).
• The patient should record their height and weight.
• Record any recent and current medication.
On the morning of the test
• The patient should bring their list of medications, and height and weight details with them.
• The patient should not physically exert themself prior to or during the test
(including brisk walking to the clinic).
Smoking may also produce a false positive result. The patient should reduce their tea and
coffee intake for three days prior to and including the day of collection.
Low Purine Diet
If your patient requires a 24 hour urine collection for uric acid, you may choose for them
to follow the diet below for three days prior to their collection:
Avoid the following:
• The patient should avoid smoking for an hour prior to and during the test. If this is not
possible then please inform staff.
• Organ meats (brain, kidney, liver)
• Green peas, dried legumes
• Wild game
• Cauliflower
• The patient is required to bring a specimen of urine, however, they should not bring the
first specimen of the morning.
• Poultry (chicken, duck, turkey)
• Asparagus
The test will take approximately 2.5 hours (half an hour rest prior to test and two hours
test time). On some occasions the length of the test may be extended.
• Meat (beef, lamb, pork, veal)
• Spinach
• Meat extracts (Bonox, Vegemite)
• Mushrooms
• Fish
• Aspirin
Urine Collection Diet For 5HIAA & Catecholamine
• Shellfish
• Cocoa.
A variety of drugs and foods are known or are reported to interfere with this particular test.
Therefore, the intake of the following items should be restricted for three days prior to and
during the urine collection:
• Wholegrain products
• Alcohol • Fruits
• Paracetamol.
The following drugs are also known to interfere with the test:
• Chlorpromazine
• Imipramine (Tofranil)
• Promazine
• Other anti-depressants
• Promethazine and other phenothiazine derivatives
• Isoproterenol • Methocarbamol (Robaxin)
• L-DOPA
• Monoamine Oxidase Inhibitors (Trandate).
The patient should not restrict or cease these drugs unless advised by their referring
doctor. Please note the above list of drugs is not fully comprehensive. If the patient is
currently taking any of the above drugs, they should list these together with a full account
of any other medications.

The value of arterial blood gases in assessing pulmonary gas exchange is well established.
However, blood gas analysis (arterial or venous) may also play a key role in assessing the
acid-base balance of the body. An easy approach to interpretation of this function is
presented below.

iii) Lactate accumulation in shock, liver disease, or exertion.
iv) Accumulation of an acidic toxin, drug, or drug metabolite
e.g. in salicylate overdose.
v) Accumulation of an unusual organic acid form inherited blockage of metabolic
pathway e.g. methylmalonic acid.
2.Normal Anion Gap
i) Enteric bicarbonate loss - biliary or pancreatic drainage.
ii)Chloride excess - rapid I.V. infusion of normal saline or urine chloride
reabsorption (ureterosigmoidostomy, ileal conduit).
iii) Renal bicarbonate loss from effective hypoaldosteronism (Adrenocortical failure,
Spironolactone therapy, aldosterone receptor defect).
iv) Renal bicarbonate loss from a tubular resorptive defect (Renal tubular acidosis,
Fanconi syndrome, carbonic anhydrase inhibitor therapy).

In categories i) and ii), the urine pH will be less than 5.0, in iii), the pH will be 6.5
or greater, and in iv) the pH will vary depending on the site of the resorptive defect
(proximal or distal tubular) and the state of compensation.
Primary Respiratory Acidosis
Examine the Base Excess
1.Respiratory Acidaemia with Normal Base Excess
Acute respiratory failure, airway obstruction or asphyxia.
2.Respiratory Acidaemia with Raised (+) Base Excess
Long standing or chronic respiratory acidosis (e.g. chronic obstructive lung disease)
with metabolic compensation.
3. Combined Respiratory and Metabolic Acidosis (Low (-) Base Excess)
Seen almost exclusively as a preterminal event.

Other patients are required to meet the lipid levels shown in the following table
after at least six weeks of dietary therapy:

Patients with diabetes mellitus
not otherwise included
Total cholesterol > 5.5mmol/L
Aboriginal or
Torres Strait Islander patients
Total cholesterol > 6.5mmol/L
or
Total cholesterol > 5.5mmol/L and
HDL cholesterol < 1mmol/L
1.Respiratory Alkalaemia with Normal Base Excess
This acute uncompensated respiratory alkalaemia pattern is common, being seen in
anxiety-associated hyperventilation (which may accompany mild asthma, mild chest
or throat constriction or pain).
Patients with hypertension
Patients with HDL cholesterol
<1 mmol/L
Total cholesterol > 6.5mmol/L
2. Primary Respiratory Alkalaemia with Low (-) Base Excess
The metabolic compensation in this case indicates a more prolonged state of
hyperventilation usually associated with respiratory centre stimulation (e.g. by mild
hypoxia in pneumonia, by protracted mild airway obstruction, or by pain or anxiety)
or with overriding of normal respiratory control e.g. with mechanical ventilation.
Respiratory centre stimulation seen with high therapeutic doses of aspirin is an
interesting and not uncommon cause.
Patients with familial
hypercholesterolaemia identified by:
• DNA mutation; or
• Tendon xanthomata in the patient or a
first or second degree relative
Patients with:
• Family history of coronary heart disease
which has become symptomatic before
the age of 60 years in one or more first

• Family history of coronary heart disease
which has become symptomatic before
the age of 50 years in one or more
second degree relatives.
If aged 18 years or less at treatment

Initiating Warfarin Therapy
When initiating warfarin therapy the loading of doses should be avoided as it causes
early procoagulant effects, and oscillating INRs that take longer to stabilise than a steady
increase in dose.
QML Pathology uses a formula that factors in each patient’s age and weight to derive
an individual dose. The formula gives us the Estimated Maintenance Dose (EMD) as
demonstrated below.

Duration of treatment depends on the site of the thrombosis and the risk status of the
patient. Those risks include re-thrombosis and bleeding from the warfarin therapy. To
enable the former to be evaluated adequately, the patient should be tested for the presence
of any inherited or acquired prothrombotic conditions, the most familiar being Factor V
Leiden, but there are others more clinically likely to affect the risks to re-thrombosis.
Warfarin is metabolised by the Cytochrome P450 system. As such there are many
drugs that can cause some change in the INR. However, there are some that have a
marked effect and which patients should be warned about. In general, every time a new
medication is commenced or one is ceased, the patient should tell the warfarin control
centre or their treating doctor, and their INR should be checked. Some medications are
notorious for interfering with warfarin. We have compiled a list of the most common and
important drugs below.

Skin Tests for Allergy
In patients with allergy due to IgE (e.g. house dust mite allergy, pollen allergy, animal
dander allergy, nut allergy) epicutaneous exposure (skin prick) to relevant allergens
induces a visible wheal and flare reaction due to local mast cell degranulation.
A set of allergens which include pollens, moulds, animal danders, house dust mite and
foods is used for testing. A histamine (positive) control and glycerol saline (negative)
control are also tested to validate the results.
Variables in Skin Allergy Testing
Several factors may influence skin testing. Clinically relevant factors include:
• Drugs e.g.:
• antihistamines
• tricyclic antidepressants
• benzodiazepines
• beta blockers.
• Age • Previous immunotherapy
• After viral exanthem.
12.37
Contraindications
Testing is contraindicated in patients with:
• Current severe allergic symptoms
• Recent anaphylaxis
• Unstable asthma
• Acute illness
• Generalised skin rash
• Pregnancy.
Allergy skin testing is performed by appointment at several locations across Brisbane
and our Branch Laboratories.
For further information, please contact our Immunology Department on (07) 3121 4458
or your local QML Pathology Branch Laboratory.

Patient Preparation
• No antihistamines to be taken for seven days prior to test. Many over-the-counter
medications (e.g. decongestants, cough mixtures and sinus mixtures) have
antihistamines; these should be ceased
• No creams or moisturisers (including sunscreen) on arms for 48 hours prior to test
• Tricyclic antidepressant drugs often have profound 'antihistamine effects' and may
preclude allergy skin testing
• Moderate to high dose oral corticosteroids, e.g. Prednisolone 25mg daily or above
will impair skin test reactivity
• Asthma sprays such as Ventolin should not be stopped.

The Doctor or Dentist and Staff
Although all of us suffer from infectious illnesses from time to time, everyone would
agree that the place where help is obtained, the Doctor’s/Dentist’s surgery, should not
facilitate transmission of infection. There is a requirement for duty of care by health care
professionals to minimise transmission of infection from person to person by careful
planning, appropriate training, and use of infection control procedures.
The surgery staff and the Doctor or Dentist should be free from infectious illness.
This document is a guide to infection control in Doctors surgeries. It does not cover all
circumstances and readers should rely on their own risk assessments and choice of
remedies required.
For more detailed guidelines see:
• Sterilisation/Disinfection guidelines for General Practice (RACGP 2007).
• Infection Control in Surgery (Royal Australasian College of Surgeons, 1998, revised 2001).
• Human Immunodeficiency Virus and Hepatitis B and the Workplace: National Consensus
Statements, Worksafe Australia Code, 1993.
• AS/NZS 4187:2003: Cleaning, disinfecting and sterilizing reusable medical and surgical
instruments and equipment, and maintenance of associated environments in health
care facilities.
• AS/NZS 4815:2006: Office-based health care facilities - Reprocessing of reusable medical
and surgical instruments and equipment, and maintenance of the associated environment.
• Updated US Guidelines for the Management of Occupational Exposures to HBV, HCV
and HIV and Recommendations for Postexposure Prophylaxis (MMWR: June 2001 Vol
50/No. RR-II).
All procedures should be documented and records of patient encounters, including small
operations lists, equipment performance, etc. should be kept.
This document is a guide for surgeries where minor procedures are performed. Facilities
for major procedures must be similar to those provided by accredited hospitals and
hence are expensive.
Factors to be considered in the control of infection are:
1. The doctor or dentist
2. The surgery staff
3. The patients
4. The physical environment
12.41
5. Disinfection and sterilization of instruments and other appliances.
All health care workers who are exposed to blood should be vaccinated with Hepatitis B
Virus vaccine. Check the serum Anti-Hepatitis B Surface antibodies (Anti HBs Ab) level 2
months after the third dose.
Skin lesions and cuts should be covered with waterproof occlusive dressings.
The surgery staff should be adequately trained in surgical procedures including aseptic
techniques, use of sterilizers etc.
These procedures should be documented. Induction of new staff and refresher training
should be recorded also.
Patients
APPENDICIES
The above concepts have now been reinforced by Government legislation. In Queensland
the relevant act is the Workplace Health and Safety Act 1995. In NSW the relevant act is
the Occupational Health and Safety Act 2000. These acts apply to all work places where
a person is paid to perform work. Breach of the Queensland Act may result in heavy fines
and/or jail of the relevant person.
They should be vaccinated against common organisms, e.g. rubella.
MICROBIOLOGY
Infection Control in Medical Consulting Rooms
Patients with suspected infectious illnesses (e.g. rubella) are best seen at their homes or
should be seen on arrival at the surgery to minimise spread of organisms to others. The
staff should arrange block bookings for pregnant patients and separate patients who
are susceptible to infection (e.g. leukaemic patients) from potential shedders of microorganisms (e.g. children with chicken pox).
Individuals, however, may have circulating transmissible agents such as Hepatitis B virus
(HBV) and Human Immunodeficiency Virus (HIV) without signs or symptoms. The blood
(and some body fluids) of such persons is infectious and thus represents a hazard when
undergoing some medical procedures.
The Centers for Disease Control, USA (MMWR 1989; 38: S–6) has developed the strategy
of ‘universal blood and body fluid precautions’ to address concerns regarding transmission
of HIV in the health care setting. The concept, previously referred to as ‘universal
precautions’, is now called ‘standard precautions with additional precautions’ and
stresses that all patients should be assumed to be infectious for HIV and other
blood-borne pathogens. In the health care setting, ‘standard precautions’ should be
followed when workers are exposed to blood and other body fluids.
Standard Precautions are recommended for the treatment and care of all patients,
and apply to all body fluids, secretions and excretions (excluding sweat), regardless of
whether they contain visible blood (including dried body substances such as dried blood
or saliva), non-intact skin and mucous membranes.
Standard Precautions include good hygiene practices, particularly washing and drying
hands before and after patient contact, the use of protective barriers which may include
gloves, gowns, plastic aprons, masks, eye shields or goggles, and appropriate handling
and disposal of sharps and other contaminated or infectious waste, and the use of
aseptic techniques.
Additional Precautions are used for patients known or suspected to be infected or
colonised with epidemiologically important or highly transmissible pathogens that
can be transmitted by air borne or droplet transmission or by contact with dry skin or
contaminated surfaces.

APPENDICIES
MICROBIOLOGY
APPENDICES - MICROBIOLOGY
To minimise the risks of acquiring HIV and HBV during performance of job duties, workers
should be protected from exposure to blood and other body fluids as circumstances
dictate. Protection can be achieved through adherence to work practices designed to
minimise risk. Personal protective equipment (i.e. gloves, masks and protective clothing)
should be used to decrease exposure to hazards.
Blood Collection
(always use gloves and protective glasses)
• Preferably use the evacuated blood tube (vacutainer®) system.
• Discard needle and syringe into sharps bin.
b. Change gloves between patient contacts.
c. Wash hands before and after using gloves.
d. Do not reuse surgical or examination gloves.
e. Use rubber household gloves for housekeeping chores involving potential blood
contact and for instrument cleaning and decontamination. These may be
decontaminated and reused but should be discarded if damaged.
f. Powder free gloves are recommended.
Hand washing Protocol
• Meticulous hand washing is essential in order to maintain infection control in the
General Practice.
• All staff should routinely wash their hands before and after all contact with
patients, as well as when cleaning up blood and body fluid spills in the surgery, and
removing gloves.
• If any blood remains on sample tube stopper clean with an alcohol swab.
• Staff should also ensure that they wash their hands before and after eating, smoking
and going to the toilet.
• Transport the blood sample safely.
• It is also essential that staff dry their hands thoroughly after washing.
Waste Management
• Any cuts, abrasions or lesions should be covered at all times with water-resistant
dressings, which should be changed regularly.
Set up proper disposal procedures. Used gloves, swabs, disposable drapes etc. should be
bagged in a biohazard plastic bag (yellow with a black biohazard symbol), sealed and disposed
of appropriately. (See Qld Refuse Management Regulation (No. 1) (amended 1993).
Environmental Protection (Waste Management) Regulation 2000 - Queensland
Under the Environmental Protection Act 1994, a clinical and related waste management
plan is required for healthcare facilities.
Handling Sharps
Take care to prevent injury when handling suture needles, scalpels, sharp instruments.
Do not resheath used needles.
Place all disposable sharp items in an approved container (AS 4031:1992) which should
be located as close as possible to the use area.
12.43
a. Use sterile gloves for procedures involving contact with normally sterile areas of
the body, e.g. wound suturing etc. Use examination gloves (clean but not sterile)
for procedures involving contact with mucous membranes and for other patient
care or diagnostic procedures not requiring sterile gloves e.g. oral, vaginal or
rectal examination.
In the event of a sharps/needlestick injury, documented protocols should outline the
action to be taken by the injured person and the treating doctor.
MICROBIOLOGY
Additional Precautions are used for patients with MRSA, VRE, CJD or active pulmonary
tuberculosis, or where there is an established risk of transmission of infection regardless
of the nature of the procedure being undertaken, or where the procedure itself carries
an established risk of aerosolation, blood accident or staff/patient injury. Additional
Precautions are not required for patients with blood borne viruses such as HIV, Hepatitis
B or Hepatitis C, unless there are complicating factors present, such as pulmonary
tuberculosis, or unless the procedure itself performed on these patients has a known
high risk, such as generation of aerosols.
Guidelines for Gloves
APPENDICIES
Additional Precautions are designed to interrupt transmission of infection by these routes
and should be used in addition to Standard Precautions when transmission of infection
might not be contained by using Standard Precautions alone. Additional Precautions may
be specific to the situation for which they are required, or may be combined where microorganisms have multiple routes of transmission.
Routine Hand Washing Procedure (10-15 seconds)
Remove all rings, watches
and jewellery.
Wet hands with warm water, apply
recommended pH neutral liquid
soap, and lather vigorously.
Wash hands thoroughly beginning
with the palms, then backs of hands,
wrists, fingers, thumbs and between
fingers for 10 to 15 seconds.

1. OVERVIEW: Validation of your steriliser
requires that you run three consecutive
steriliser cycles. Each cycle must include
two biological indicator vials inside the
steriliser (one inside a pack, the other
outside the pack(s)). The remaining vial
is NOT sterilised, but acts as a control of
storage and transport conditions.
3. Validation of the sterilisation process
should be performed as soon as practical
after the technician’s annual service.
4. Preclean, wash and dry the items
for sterilisation.
5. Ensure seven vials received and all have
the same lot/batch number. Label six vials
to indicate their location and cycle number
(see table) and label remaining vial as 'Z' to
be used as a control.
6. Select the most difficult to sterilise pack
and load* and record contents. Place one
indicator (i.e. '1E' for the first cycle) inside
the middle of challenge pack.
Steriliser chamber
7. Put this pack in the steriliser and place
a second indicator vial (i.e. '1C' for the
first cycle) in the coolest position in the
steriliser as identified from heat distribution
studies**. NB: Ensure vial does not come
into contact with metal as it will melt.
Place vial on gauze or paper so that it
does not make contact with the metal of
the autoclave.
Control vial outside
steriliser labelled Z
Vial inside package
labelled E
8. Run the steriliser for one cycle. The
length of the sterilisation period should be
three minutes plus the penetration time ** if
running at 134˚C.
9. Run two more cycles, repeating steps
4 to 6 each time. Use identical packages
with new indicator vials in the same
positions as before:
2nd cycle – use vials labelled 2C and 2E.
3rd cycle – use vials labelled 3C and 3E.
The one control vial 'Z' is NOT exposed to
the sterilisation cycle.
10. Keep a record of the date and time the
validation was performed, the time and
temperature for the cycles, the package
contents and the position of the pack(s) in
the steriliser.
11. Complete validation request form and
send along with the seven vials to the
laboratory for processing.
12. Validation does not need to be repeated
for another 12 months unless pack and/or
packaging density change, or the steriliser
undergoes a major service.
* The hardest to sterilise pack possible for your surgery in terms of packaging and pack density. Must also provide the
largest load possible for the steriliser.
** Heat distribution studies and penetration times should be provided by the technician as part of the annual service.

What to do after validation
After successful validation, biological indicator vials are not required for
routine monitoring of your steriliser. For routine monitoring you must either:
1. R
ecord cycle parameters (time and temperature) either manually every 30 seconds or
using a printout from the steriliser.
OR
2. Use a Class 4, 5, or 6 chemical indicator.
NB. All packages should include an external Class 1 indicator (autoclave tape)
to identify those packages that have been sterilised. Quality Control (QC) is performed on all batches of vials before they are distributed
to surgeries.
