<<Disclaimer: Verify this information before applying it to your situation.>> I am curious to know if there is a way to find out if wheat or gluten is the cause of my problems. Because of the results of my duodenal biopsy (flattened mucosal), I was advised to go on a gluten free diet, to which I responded. However, when querried., my gastoenterologist stated that wheat intolerance would give the same biopsy results. While eating wheat, but not gluten, free products had been overtly tolerated, I fear continuing doing so if it is causing damage at the cellular level. Could any of the antibody tests that I've been hearind about (anti-gliadin, anti-endomysial) help to make the differential diagnosis? I would appreciate any input. Thanks, Ellen Eagan
