tTG antibodies

**tTG antibodies**

tTG antibodies, or tissue transglutaminase antibodies, are autoantibodies commonly tested for in the diagnosis of celiac disease. These antibodies target the enzyme tissue transglutaminase, which plays a key role in gluten metabolism and immune response in the small intestine. Elevated levels of tTG antibodies typically indicate an immune reaction to gluten and can help confirm celiac disease or related gluten sensitivity disorders. Testing for tTG antibodies is a crucial step in identifying gluten-induced autoimmune conditions and guiding appropriate dietary management.
