I posted about this before, but I had celiac labwork done about a year and half ago, and then went on a gluten-free diet on the advice of my doctor. There was an immediate improvement, and it seems pretty clear that I'm intolerant to gluten. Then, the labwork came back "negative" but confusing. Some of the numbers were odd and no one seemed to know what they meant, but agreed I must not have celiac. At the time, I thought due to things I had observed, that it was possible the lab had mishandled the samples. My doctor didn't think I should go back on gluten just to get retested since I was doing so well on the gluten-free diet. Then, last week I had the genetic testing done and it came back DQ2.5/DQ8. Long story short, it looks like I do have celiac after all.
