Test ID: CDCOM    
Celiac Disease Comprehensive Cascade, Serum and Whole Blood

Useful For Suggests clinical disorders or settings where the test may be helpful

Evaluating patients suspected of having celiac disease, including patients with compatible symptoms, patients with atypical symptoms, and individuals at increased risk (family history, previous diagnosis with associated disease)


Comprehensive algorithmic evaluation including HLA typing

Profile Information A profile is a group of laboratory tests that are ordered and performed together under a single Mayo Test ID. Profile information lists the test performed, inclusive of the test fee, when a profile is ordered and includes reporting names and individual availability.

Test IDReporting NameAvailable SeparatelyAlways Performed
IGAImmunoglobulin A (IgA), SYesYes
CELI2HLA-DQ TypingYes, (Order CELI)Yes
CDCM1Celiac Disease InterpretationNoYes

Reflex Tests Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Test IDReporting NameAvailable SeparatelyAlways Performed
EMAEndomysial Abs, S (IgA)YesNo
DAGLGliadin(Deamidated) Ab, IgA, SYesNo
TTGGTissue Transglutaminase Ab, IgG, SYesNo
DGGLGliadin(Deamidated) Ab, IgG, SYesNo
TTGATissue Transglutaminase Ab, IgA, SYesNo

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If IgA is age-specified normal, then tissue transglutaminase (tTG) IgA will be performed at an additional charge.


If tTG IgA is equivocal, then endomysial antibodies IgA and deamidated gliadin antibody IgA will be performed at an additional charge.


If IgA is greater than or equal to 1.0 mg/dL but lower than age-specified normal, then tTG IgA, tTG IgG, deamidated gliadin IgA, and deamidated gliadin IgG will be performed at an additional charge.


If IgA is below detection (<1.0 mg/dL), then tTG IgG and deamidated gliadin IgG will be performed at an additional charge.
