Currently, there is no test to determine true "gluten sensitivity." We have tests for Celiac and tests for wheat allergy, but no current test for gluten sensitivity/intolerance. The only way to determine gluten sensitivity is to exclude it from the diet for a few months to see if symptoms improve.

Mark Hyman, MD, Family Medicine, answeredThere are gluten allergy/celiac disease tests that are available through Labcorp or Quest Diagnostics. All these tests help identify various forms of allergy or sensitivity to gluten or wheat. They will look for:
- IgA anti-gliadin antibodies
- IgG anti-gliadin antibodies
- IgA anti-endomysial antibodies
- Tissue transglutaminase antibody (IgA and IgG in questionable cases)
- Total IgA antibodies
- HLA DQ2 and DQ8 genotyping for celiac disease (used occasionally to detect genetic susceptibility).
- Intestinal biopsy (rarely needed if gluten antibodies are positive -- based on my interpretation of the recent study)
We can no longer say that. Positive is positive and, as with all illness, there is a continuum of disease, from mild gluten sensitivity to full-blown celiac disease. If your antibodies are elevated, you should go off gluten and test to see if it is leading to your health problems.
