Test ID: CDGF    
Celiac Disease Gluten-Free Cascade

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

Evaluating patients suspected of having celiac disease who are currently (or were recently) on a gluten-free diet

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
CELI2HLA-DQ TypingYes, (Order CELI)Yes
CDGF1Celiac Disease InterpretationNoYes

Reflex Tests Lists test(s) that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial test(s)

Test IDReporting NameAvailable SeparatelyAlways Performed
TTGATissue Transglutaminase Ab, IgA, SYesNo
DAGLGliadin(Deamidated) Ab, IgA, SYesNo
DGGLGliadin(Deamidated) Ab, IgG, SYesNo
TTGGTissue Transglutaminase Ab, IgG, SYesNo
IGAImmunoglobulin A (IgA), SYesNo

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

If HLA-DQ typing is positive or equivocal for DQ2 or DQ8, then IgA, tissue transglutaminase (tTG) IgA and IgG, and deamidated gliadin IgA and IgG will be performed at an additional charge.
