Tissue Transglutaminase IgA

This add-on measures the level of tissue transglutaminase IgA (TAA) antibodies in your blood, a key marker used to screen for coeliac disease. These antibodies are produced by the immune system in response to gluten in individuals with gluten sensitivity or autoimmune reactions. Elevated TAA levels may indicate coeliac disease or gluten-related inflammation—even if signs are subtle or not yet noticeable. Please note that this add-on requires a longer processing time—results will be available within 6 business days.Read our complete guide to Tissue Transglutaminase IgA →
