<<Disclaimer: Verify this information before applying it to your situation.>> I apologize if this has already been posted here. I found this tonight on clinicaltrials.gov: Information provided by: University of British Columbia ClinicalTrials.gov Identifier: NCT00175760 Purpose This study is to see if a high response to the TTG screening test for celiac disease is as accurate as the current method of diagnosing celiac disease which entails a general anesthetic and upper endoscopy to obtain biopsies of the small intestine. If the screening blood test is highly accurate, then some patients that are being evaluated for celiac disease may not require an upper GI endoscopy and can be treated more quickly. If they respond to the therapy then they will be deemed to have celiac disease. Full details and easy instructions are on the site which is owned by the n.i.h. *Support summarization of posts, reply to the SENDER not the CELIAC List*
