Endomysium Ab.IgA

This test detects IgA antibodies to endomysium, the tissue surrounding muscle fibers. The endomysium IgA test is highly specific for celiac disease, an autoimmune condition triggered by gluten consumption. A positive result strongly suggests celiac disease, especially when combined with tissue transglutaminase (tTG-IgA) testing. This test is used for screening and diagnosis of celiac disease in patients with suspected gluten sensitivity. A positive result typically warrants follow-up with intestinal biopsy for confirmation.
