# Celiac Antibodies Profile tTG IgA, tTG IgG, DGP IgA, DGP IgG, and Total IgA

> This test measures specific antibodies in your blood that the immune system produces in response to gluten and tissue transglutaminase. It helps show if eating wheat, barley, or rye is triggering an immune reaction that damages the lining of your small intestine. Doctors use these results to help identify or rule out Celiac disease as the cause of digestive symptoms. However, this test cannot confirm a diagnosis by itself and may not provide accurate results if you have already removed gluten from your diet.
