About this test
The antibodies only appear while gluten is being eaten, so cutting it out before testing is the commonest reason for a false negative. Total IgA is measured alongside, because IgA deficiency is over-represented in coeliac disease and would otherwise hide a positive.
What it measures
- Tissue transglutaminase IgA
- Endomysial antibody IgA
- IgG-based testing where IgA is deficient
A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
