Celiac Antibodies tTG IgA, EMA IgA, Total IgA With Reflex to tTG IgG

This panel measures specific antibodies in your blood that the immune system creates in response to gluten, a protein found in wheat, barley, and rye. It also checks your total level of immunoglobulin A (IgA) to ensure the antibody results are accurate. This test helps show whether your immune system is attacking the lining of your small intestine, which is often the cause of chronic digestive problems or unexplained weight loss. While it helps identify potential Celiac disease, a positive result typically requires a tissue biopsy to confirm the diagnosis.
