The Tissue Transglutaminase Antibody IgA test is an important blood test used to diagnose celiac disease, an autoimmune disorder. In individuals with celiac disease, the immune system mistakenly targets gluten—a protein found in wheat, rye, barley, and oats—by producing anti-tissue transglutaminase antibodies. These antibodies attack the enzyme tissue transglutaminase (tTG), which is essential for repairing intestinal damage. Elevated levels of these antibodies indicate an immune response to gluten, leading to damage in the small intestine and symptoms like abdominal pain, anaemia, fatigue, and malnutrition. The Tissue Transglutaminase Antibody IgA test assists doctors in diagnosing celiac disease and is also useful for monitoring the effectiveness of a gluten-free diet in diagnosed individuals.

If you’re in Noida and experiencing gluten sensitivity, consider scheduling a Tissue Transglutaminase Antibody IgA test to determine if celiac disease is the cause of your symptoms.

Prerequisites: Fasting is not necessary, a blood sample is required for the Tissue Transglutaminase antibody IgA test. Best Time to Get Tested: The test can be taken at any time of the day unless otherwise advised by a doctor. When Recommended: To be conducted as per the doctor’s prescription. Cautions: No specific precautions are required before the test.

Screens for celiac disease by detecting antibodies against tissue transglutaminase, a key marker for gluten intolerance.
