Anti-Tissue Transglutaminase IgA Test
The gold standard test for diagnosing celiac disease by measuring IgA antibodies to gluten. Early detection helps prevent intestinal damage and guides you toward a healthier, gluten-free lifestyle.

Anti tissue transglutaminase IgA analysis (Anti Tissue Transglutaminase IgA, Serum) is a laboratory test used to diagnose celiac disease, a condition that affects the digestive system as a result of an immune reaction to gluten. The test measures the level of antibodies in the blood, helping to determine whether there is an abnormal reaction to gluten. This analysis is considered an important tool for diagnosing food sensitivities and guiding appropriate treatment.
Levels are considered normal if they are below 20 U/mL, although normal ranges may vary slightly between laboratories.
