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

This profile measures specific antibodies that the immune system creates in response to eating gluten, a protein found in wheat, barley, and rye. It helps show whether the body is attacking the lining of the small intestine, which is useful for investigating symptoms like chronic diarrhea, bloating, or weight loss. These results assist doctors in distinguishing Celiac disease from other digestive disorders. However, this blood test cannot replace an intestinal biopsy for a final confirmation or detect gluten sensitivity that is not autoimmune in nature.
