Use

This test is crucial for evaluating patients suspected of having celiac disease. It is used to test patients who present with compatible clinical symptoms, atypical symptoms, and those at increased risk due to factors like family history or previous diagnosis with associated conditions. It screens for dermatitis herpetiformis and monitors response to a gluten-free diet in patients with dermatitis herpetiformis and celiac disease. The presence of tissue transglutaminase antibodies is consistent with a diagnosis of celiac disease and possibly dermatitis herpetiformis. For individuals with moderately to strongly positive results, a celiac disease diagnosis is possible, and a small intestinal biopsy may be indicated for confirmation.
