Glucose Meter Base Unit
• Return the Inform II meter to any
base unit when finished with
patient testing to charge the
battery.
• A drained battery will take 1 hour
to reach full charge.
• Docking the meter also
synchronizes the information in
the meter with the system (patient
lists, operator lists, strips and
controls).
Glucose Reagents
• Only Accu-Chek Inform II Test Strips and Glucose Control Solutions
can be used with the hospital Inform II glucose meter.
Glucose Test Strip
• Test strips are stored in the tightly capped
original container. There is a dessicant in
the cap that keeps the strips from being
exposed to humidity.
• The container must remain closed.
Improperly stored Test Strips will produce
inaccurate results and must be discarded.
• Test strips can be used until the expiration
date printed on the vial.
• You may discard the code key that comes
with every vial of strips.
Glucose Liquid Quality Controls (QC)
• Opened control solutions expire
3 months from opening or the “Use
by” date on the bottle, whichever
comes first.
• Control solutions must be dated
with both the open and discard
dates.
Glucose QC
• Both low and high level control must be tested every 24 hours.
• Each time QC is tested, the 24-hour clock resets.
• The Inform II meter is locked for patient testing until both low and
high level QC PASS.
• QC should also be tested following these conditions:
– Patient test results are questionable.
– New test strip vial is opened.
– New control solutions are opened.
– The Inform II has been dropped or mishandled.
Performing Glucose QC
• Perform hand hygiene and don gloves before
•

the strips you are using.
• Aim the scanner at the vial of
strips and press the barcode
icon to scan.
Performing Glucose QC continued
• The meter is now ready
for you to insert a strip.
• The gold end of the strip
goes into the meter with
the writing side up.
Performing Glucose QC continued
• The meter is now
ready for you to
apply the control
solution to the strip.
• Hold the meter
horizontally when
performing QC and
dispense a small
drop into the sample
window at the end of
the strip.
Performing Glucose QC continued
• An hourglass will be
displayed briefly.
• If the hourglass does not
appear and the blood drop
icon is still flashing, you can
add more sample within five
seconds.
• The glucose meter should
remain horizontal during
testing.
Performing Glucose QC continued
• After 5 seconds, the Pass/Fail QC
results will be displayed.
• Press the checkmark (√) to accept
the result and return to the menu.
• If that level of QC has Passed,
repeat the QC process with the
other level.
• Both High and Low QC levels
must pass to unlock the meter for
patient testing.
Performing Glucose QC continued
• If QC should fail, an “Out of
Range” message will display
onscreen and the comment bubble
icon will flash.
• Touch the comment bubble (
) to
select the appropriate comment(s).
• Repeat QC. If QC fails again, try
another vial of strips or another
bottle of liquid QC.
• Both levels of QC must pass to
unlock the meter for patient testing.
Glucose Patient Testing
• Once both levels of QC have passed, the meter will be unlocked for
patient testing.
• Arterial, venous, capillary, or neonatal whole blood specimens are
acceptable. Cord blood samples cannot be used.
• Hematocrit should be between 10–65 %.
• Lipemic samples (triglycerides) in excess of 1800 mg/dL may produce
elevated results.
• Blood concentrations of galactose >15 mg/dL will cause
overestimation of blood glucose results.
• The performance of this system has not been evaluated in the critically ill.
When should a venous or arterial sample be
tested instead of a finger stick?
• Finger stick or capillary samples should not be tested on patients
exhibiting decreased peripheral blood flow.
• Examples:
– Severe dehydration caused by diabetic ketoacidosis
– Hyperglycemic hyperosmolar non-ketotic state
– Hypotension
– Shock
– Peripheral vascular disease
• In these cases, venous or arterial blood samples should be obtained.
Performing a Glucose Patient Test
• Once both levels of QC have
•
•
passed, the meter will be
unlocked for patient testing.
Turn the meter on using the
power button on the front of
the meter.
After the meter performs its
self-checks, scan your
Operator ID.

INPATIENT PATIENT ID
•If the patient has been admitted to your inpatient unit, the
patient’s MRN and name will be displayed on screen.
•Verify that the patient information is correct and touch YES or
NO accordingly.
•For Outpatient Testing, see the next page.
Performing a Patient Test continued
PATIENT NOT FOUND MESSAGES (Includes Outpatients)
•If the patient name does not appear for inpatient units:
- Redock the meter to update patient information
- Redock the meter if the patient is a recent admission or transfer.
- Check that the Patient’s ID bracelet is not smudged and barcode is clear.
•If the patient’s name still does not appear, or if the patient is an
outpatient, you must double check the number on the wristband against the
number you entered into the meter.
•Once you have re-verified the patient’s identification,
– Touch YES if displayed MRN matches that on the patient’s wristband.
– Touch NO if displayed MRN does not match the wristband.
Glucose Patient Testing continued
• Hold Accu-chek meter horizontally.
• Always wipe away the first drop of blood
from a finger stick before touching test
strip to finger.
• Avoid getting blood in the test strip port.
• Only a small quantity of blood needs to
be applied to the strip.
• If the hourglass does not appear and the
test has not started, you may add more
blood to the strip within 5 seconds.
Glucose Patient Test Results
• Touch the Checkmark ( √ )
icon to accept the result.
• Optional: touch the Comment
Bubble (
) icon and enter a
custom comment or select one
from the list.
• Enter the glucose result into the
Clinical Information System
immediately.
Glucose Results: Normal & Critical Ranges
• Normal fasting range for a glucose patient result on the Inform II is 60 – 100
mg/dL.
• Test results <10 mg/dL will be displayed as “LO” and > 600 mg/dL) will be
displayed as “HI”.
• The Inform II requires entry of a comment to a critical test result. Multiple
pre-defined comments are available, or users can enter a free text comment.
• Critical glucose patient results are:
Adults:
<40 mg/dL or >500 mg/dL
Neonates:
<50 mg/dL or >500 mg/dL
Critical Results
Any critical result MUST be communicated to the physician and
addressed:
• Document action in the meter using an appropriate comment. You cannot
proceed with further testing until a comment is attached to the critical
results.
•Critical glucose results >500 mg/dL should be confirmed by a sample sent
sample to the clinical lab.
• The RN must notify the physician of the critical result and document
notification and verbal read back in the patient’s chart.
Critical Results
Reference the following Nursing policies and procedures regarding
critical results:
•IV-B-13 Administration of Continuous Intravenous Insulin Infusion (CIII)

•When docking is complete, the meter display will read
“Idle”. Do not remove the meter from the base until
“Idle” is displayed.
•Remove the meter from the base. Turn it on to check
that the reset worked. If needed, perform Hi/Lo QC.
•If these techniques do not work, contact Point of Care:
Center City x51664, Methodist x242-9989
Infection Control
• The device should be cleaned and disinfected between patients, per
manufacturer’s instructions, to prevent carry-over of blood and
infectious agents.
• Squeeze out excess fluid from any wipes before wiping the meter. Do
not allow any moisture in the test strip port when cleaning.
• Accu-Chek recommends any of the following:
-Alcohol Prep-Pads (70% isopropyl alcohol solution)
-Clorox wipes (10% bleach solution)
-Sani-Master 4 (Sani-Cloth) wipes (quaternary ammonium compounds):
Center City Locations
-3M #5 Quat wipes (quaternary ammonium compounds): Methodist Locations
Infection Control
• Follow hospital infection control guidelines at all times.
• Perform hand hygiene and don gloves before performing glucose
testing.
• Sharps must be discarded in puncture proof containers.
• All other biohazardous waste must be discarded in designated
containers.
Testing Personnel
• Only trained personnel are permitted to perform point of care glucose
testing.
• New users receive certification upon completion of initial training.
• To maintain glucose testing privileges, each user must be assessed for
competence annually by passing a short quiz and through successful
testing of Hi/Lo QC within 60 days of their competency expiration.
• Operators who have not been recertified will be automatically locked
out of the meter.
