Sample Celiac Disease Comprehensive Panel Report Test Ordered Test Name Celiac Disease Comprehensive Panel* Interpretation Serological evidence for celiac disease is present. Consider IgA deficiency. Tissue Transglutaminase An IgA and/or IgG test is used to detect antibodies directed at this enzyme commonly found in the intestines. Test Results Reference Range Level of Antibody Detected <4 U/mL: TISSUE TRANSGLUTAMINASE AB, IGA No Antibody Detected <1 (tTg IgA) >4 U/mL: Antibody Detected IGA, SERUM (Total IgA) ENDOMYSIAL ANTIBODY SCR (IGA) W/REFL TO TITER 22 L 24 H No Antibody Detected >6 U/mL: NEGATIVE (EMA) ENDOMYSIAL ANTIBODY TITER 1:160 H No Antibody Detected Consider IgA deficiency as number is not in the normal range of 24-121 mg/dL. Antibody Detected POSITIVE ABSENT <4 U/mL: LOW 24-121 mg/dL <6 U/mL: TTG ANTIBODY, IGG (tTg IgG) Confirmation These tests usually correlate with tTg. However, it is ordered as a confirmation when patients have had positive results from other celiac disease antibody tests. Flag PRESENT >6 U/mL: Antibody Detected POSITIVE EMA IgA confirms the positive tTG IgG <1:5 TITER Results out of range Interpreting Celiac Disease Comprehensive Panel Test Results No Indication of Celiac Disease Inconclusive Suggestive of Celiac Disease Highly Suggestive of Celiac Disease tTg IgA=Negative Total IgA=Normal tTg IgA=Positive Total IgA=Normal EMA=Negative tTg IgA=Negative Total IgA=Low tTG lgG=Positive tTg IgA=Positive Total IgA=Normal EMA=Positive tTg IgA=Negative Total IgA=Low tTG IgG=Negative tTg IgA=Negative Total IgA=Low tTG IgG=Positive EMA=Negative tTg IgA=Positive Total IgA=Low tTG IgG=Positive EMA=Positive tTg IgA=Positive Total IgA=Low tTG IgG=Positive EMA=Negative tTg IgA=Negative Total IgA=Low tTG IgG=Positive EMA=Positive If test results do not suggest the presence of celiac disease, confirm your patient was eating a normal, gluten-containing diet for at least 2 weeks prior to getting tested. If not, the test results may have been compromised. If the patient was eating normally, there is a chance he or she has non-celiac gluten sensitivity. *For children up to age 4, use the Celiac Disease Comprehensive Panel, Infant. © Copyright 2014 Quest Diagnostics Incorporated.
