Yup. And if you haven't been eating wheat your antibody test will be negative no matter what, like you found.

You need to be "fighting" the gluten protein for you body to be producing the antibodies. When my GI doc was talking about having me do an antibody or small intestine biopsy test, he wanted me to eat 6 slices of bread a day for 2 weeks to get the antibodies up to steam and detectable before the blood draw.

I said, "No, I'll die." And I was only being a little hyperbolic.

Since that earlier post of mine two years ago, the gold standard for celiac/gluten intolerance has changed. Now there are other blood markers that are turning out to be more reliable indicators, and the dietary change and symptom results are being trusted more. Quite a few researchers are doubting the idea that the small intestine biopsy is the definitive test. Insurance companies are lagging behind, but isn't that always the way it is?

Anyone who thinks they may have celiac should really do a lot of research before going for the various tests, including the genetic tests. (find out if your insurance pays for them, for one thing!)
