Testing. A simple blood test is available to test for celiac disease. People with celiac disease who eat gluten have higher than normal levels of certain antibodies in their blood. These antibodies are produced by the immune system because it views gluten (the proteins found in wheat, rye and barley) as a threat.

The allergist will usually order a blood test (such as an ImmunoCAP test) and/or perform a skin prick food allergy test, both of which indicate whether food-specific IgE antibodies are present in your body. Skin prick tests are conducted in a doctor's office and provide results within 15-30 minutes.
