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

If the IgA-endomysial antibodies result is positive or indeterminate, then the antibody titer will be performed at an additional charge.

 

The following algorithms are available in Special Instructions:

-Celiac Disease Comprehensive Cascade

-Celiac Disease Diagnostic Testing Algorithm

-Celiac Disease Gluten-Free Cascade

-Celiac Disease Routine Treatment Monitoring Algorithm

-Celiac Disease Serology Cascade

Specimen Type Describes the specimen type validated for testing

Ordering Guidance

Cascade testing is recommended for celiac disease. Cascade testing ensures that testing proceeds in an algorithmic fashion. The following cascades are available; select the appropriate one for your specific patient situation.

-For complete testing including human leukocyte antigen (HLA) DQ, order CDCOM / Celiac Disease Comprehensive Cascade, Serum and Whole Blood

-For complete testing excluding HLA DQ, order CDSP / Celiac Disease Serology Cascade, Serum

-For patients already adhering to a gluten-free diet, order CDGF / Celiac Disease Gluten-Free Cascade, Serum and Whole Blood

 

To order individual tests, see Celiac Disease Diagnostic Testing Algorithm in Special Instructions.
