Does a colonoscopy detect celiac disease?

A colonoscopy isn't necessary for diagnosing celiac disease, but some specialists may suggest it to get the bottom (sorry) of your symptoms. A colonoscopy allows doctors to see the large intestine whereas celiac disease involves the small intestine, Dr. Bilchik explains.

How does a doctor test for celiac disease?

Two blood tests can help diagnose it: Serology testing looks for antibodies in your blood. Elevated levels of certain antibody proteins indicate an immune reaction to gluten. Genetic testing for human leukocyte antigens (HLA-DQ2 and HLA-DQ8) can be used to rule out celiac disease.
