Will A Biopsy Show Celiac Disease?
Yes, a biopsy can show celiac disease. A biopsy involves taking a small tissue sample from the small intestine, and examining it under a microscope for signs of damage to the villi. The damage to the villi is caused by the immune system’s reaction to gluten, a protein found in wheat, barley, and rye. If the biopsy shows flattened or damaged villi, it is a clear indication of celiac disease.
