<<Disclaimer: Verify this information before applying it to your situation.>> Hi All-- I've recently noticed posts from people who have had DNA testing for the celiac marker, but I've not noticed any information on how to go about having the test done, what does the doctor need to request, are certain labs better than others, and how reliable is the testing? Since my tests came back as "unconfirmed Celiac," but with a positive malabsorption test result, I'm wanting more definite information. I'm too sensitive to gluten for my GI doc to agree to a challenge, so the DNA testing is our last option. Though the treatment won't change, it's possible that a positive or negative DNA test could impact issues such as insurance, etc. Can anyone share info re: this issue? I would appreciate it...I'll summarize if others indicate an interest. Thanks. Ayn/Kansas
