Q. When should you consider getting tested?
A. You should get tested if someone in your family has celiac disease, especially a first- or second-generation relative, such as a sister, cousin or uncle. Be sure to get tested if you have an associated autoimmune disease or GI problems of unknown origin. Blood tests are used as a screening tool. If they are positive, then a small intestinal biopsy is performed. If you have a skin rash, you might also have a skin biopsy to confirm whether you have DH.
