The Tissue Transglutaminase IgA test measures IgA antibodies directed against tissue transglutaminase, an enzyme involved in normal intestinal function. Elevated tTG IgA antibodies are highly associated with celiac disease and are commonly used as a primary screening test.
This test is typically ordered when symptoms such as chronic diarrhea, abdominal pain, bloating, unexplained weight loss, or nutrient deficiencies are present. It is often performed alongside total IgA testing to ensure accurate interpretation and may be included as part of a comprehensive celiac disease evaluation.
