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
Specimen Type Describes the specimen type validated for testing
Ordering Guidance
-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.
