Test ID: CDSP
Celiac Disease Serology Cascade
Secondary ID 
A test code used for billing and in test definitions created prior to November 2011
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, positivity for DQ2 and/or DQ8)
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 ID | Secondary ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|---|
| IGA | 8157 | Immunoglobulin A (IgA), S | Yes | Yes |
| CDSP1 | 29458 | Celiac Disease Interpretation | No | Yes |
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 ID | Secondary ID | Reporting Name | Available Separately | Always Performed |
|---|---|---|---|---|
| EMA | 9360 | Endomysial Abs, S (IgA) | Yes | No |
| DAGL | 89029 | Gliadin(Deamidated) Ab, IgA, S | Yes | No |
| TTGG | 83660 | Tissue Transglutaminase Ab, IgG, S | Yes | No |
| DGGL | 89030 | Gliadin(Deamidated) Ab, IgG, S | Yes | No |
| TTGA | 82587 | Tissue Transglutaminase Ab, IgA, S | Yes | No |
Testing Algorithm Delineates situation(s) 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 deaminated gliadin antibody IgA will be performed at an additional charge.
If IgA is > or =1.0 mg/dL but lower than age-specified normal, then tTG IgA, tTG IgG, deaminated gliadin IgA, and deaminated gliadin IgG will be performed at an additional charge.
If IgA is below detection (<1.0 mg/dL), then tTG IgG and deaminated gliadin IgG will be performed at an additional charge.
