Celiac Disease Dual Antigen Screen with Reflex
2002026
 
Ordering Recommendation
Acceptable reflexive screening test for celiac disease. Positive screen results reflex to IgA and IgG antibody testing for tissue transglutaminase antibody (tTG) and deaminated gliadin peptide antibody (DGP). Preferred screening test is Celiac Disease Reflexive Cascade (2008114) or Tissue Transglutaminase ( tTG) Antibody, IgA (0097709) testing.

Reference Interval
Test Number Components Reference Interval
0051689Celiac Disease Dual Antigen Screen 19 Units or less: Negative -​ No significant level of detectable IgA or IgG antibodies against human tissue transglutaminase or gliadin peptide.

20 Units or greater: Positive -​ Presence of IgA and/or IgG antibodies against human tissue transglutaminase and/or gliadin peptide; suggests possibility of certain gluten sensitive enteropathies such as celiac disease and dermatitis herpetiformis.

Interpretive Data
Refer to individual components.
Note
The Celiac Disease Dual Antigen Screen is a combined antibody assay for tissue transglutaminase and deamidated gliadin-derived peptide antibodies, IgA and IgG.

If Celiac Disease Dual Antigen Screen is 20 Units or greater, then tTG IgA and Gliadin Peptide IgA will be added. If tTG IgA and Gliadin Peptide IgA are negative, tTG IgG and Gliadin Peptide IgG will be added. Additional charges apply.
CPT Code(s)
83516 Dual antigen screen. If Dual antigen screen is 20 Units or greater, add 83516 tTG IgA and 83516 Gliadin IgA. If tTG IgA and Gliadin IgA are negative, add 83516 tTG IgG and 83516 Gliadin IgG.
