<<Disclaimer: Verify this information before applying it to your situation.>> Hi Gang! I am an undiagnosed celiac (GF for two years) and recently approached my doctor about it. She wanted to give me the antibody blood tests to test for celiac sprue. When I mentioned that one must be on a gluten-containing diet for the tests to come out positive, she said no, one didn't. She stated that the antibodies live in the body for years. However, she promised (and she was very genuine) to send me some articles on this subject. So I was wondering if anyone knew of a good medical website stating that a patient needs to be on a gluten-containing diet in order to test positive so that I could send her info too. I'd like to educate another doctor concerning celiac, especially since this one seems willing to learn. Sincerely, Dawn Los Angeles
