TISSUE TRANSGLUTAMINASE – IGA (TTG)

The tissue transglutaminase (tTG) IgA test detects IgA antibodies against tissue transglutaminase, an enzyme involved in the immune response to gluten. This test is used to diagnose celiac disease, an autoimmune disorder triggered by gluten ingestion. Elevated tTG IgA levels indicate an immune response to gluten, supporting the diagnosis of celiac disease. The test is valuable for diagnosing celiac disease, guiding treatment decisions, and monitoring adherence to a gluten-free diet. It provides important information for managing celiac disease and preventing complications associated with gluten intolerance.
