Gliadin Antibodies (AGA); Endomysial Antibodies; Tissue transglutaminase antibody (tTG)
(Celiac Disease Tests)

Alternate Names

  • Gluten-Sensitive Enteropathy Tests

People who have celiac disease are unable to digest the proteins that are present in wheat. These proteins are toxic to the lining of the small intestine, causing inflammation and ulcers on the lining of the intestine which results in a decreased ability to absorb all nutrients. Levels of antibodies to gluten, gliadin, endomysial, and tissue transglutaminase antibody (tTG) increase in the bloodstream. High levels of these antibodies are measured and help your doctor diagnose celiac disease, and to also monitor your response to treatment and how well you are following a gluten-free diet.
