I am looking into this. I have had the blood test, but it does not show a problem with gluten/celiac. However, I do know the stool test (which can also do a genetic test for it) is more likely to show gluten problems even when blood test shows it is not an issue. But I, alas, I'm going to have to postpone a little while. I can't afford the test right now (it's not horribly expensive, but my husband is out of work right now, so I need to watch the budget closely). Cutting wheat/gluten out of my diet doesn't seem to make any difference for me, but I haven't been faithful about keeping it out long enough to know for sure.
