IgA tTG

S-tTG IgA is an acronym for a serological test for antibodies (type IgA) against tissue transglutaminase (tTG) in the blood. This test is often used to detect celiac disease. Antibodies against tTG increase in the body when a person with celiac disease is exposed to gluten. Therefore, the presence of these antibodies in the blood is a strong indicator of active disease.
