Frequently Asked Questions
Can a skin biopsy for dermatitis herpetiformis (DH) confirm celiac disease or is an endoscopy still needed?
A skin biopsy should be done on a non-affected portion of the skin near the rash when there is an outbreak. It’s not necessary to perform an intestinal biopsy to establish the diagnosis of celiac disease in a patient with DH; the skin biopsy is definitive. July, 2012
