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.

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 IgA antibodies against human tissue transglutaminase and/or gliadin peptide; suggests possibility of certain gluten sensitive enteropathies such as celiac disease and dermatitis herpetiformis.

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.
