Diagnosis begins with serologic testing and is confirmed by biopsy. Celiac disease antibody tests help diagnose and monitor the disease and a few other gluten sensitive conditions. In terms of serology celiac disease is associated with a variety of autoantibodies including endomysial tissue transglutaminase ttg and deamidated gliadin antibodies. It is present in high concentrations in the mucus membranes of the stomach.

These tests detect autoantibodies in the blood that the body produces as part of the immune response. All celiac disease blood tests require that you be on a gluten containing diet to be accurate.
