<<Disclaimer: Verify this information before applying it to your situation.>> Thanks for the overwhelming number of e-mails regarding HLA testing. I heard from many people who are wondering if HLA testing would provide a definitive diagnosis. Bill Elkus suggests reading the list archive on HLA testing. I hope my interepretation of this summary is correct: DR3, B8 and DQ2 markers are associated with CD. To a lesser extent DR4 and DQ8 molecules are associated with CD. "Some very few Celiacs are neither DQ2 nor DQ8 implying that HLA typing is not a perfect predictor of risk for Celiac Disease". I'll be the first to say that I need "HLA for Dummies". Perhaps (after reading the archive) people could e-mail any questions to me. I will consolidate and post them. Further questions: if there were many people interested in HLA testing, is there a lab that would test us as a group? Would anyone be interested in conducting a study of "unconfirmed celiacs" with correlative HLA testing? Thanks for all your replies! Sally
