I agree with Glenntag. They can't actually test for gluten sensitivity as of yet. The only test they think they have so far is for flattened villi, which in it's self is not conclusive of celiac disease, there are other issues that can flatten villi...so, as far as I am concerned, it's still a guessing game.
I have double DQ1 genes, which they have proven are gluten intolerant genes, just by the numbers of people with DQ1 whom can't tolerate gluten. For me though, I can't tolerate any grains, even the ones they call gluten free, which really aren't gluten free in any sense.
Check out this website:
www.glutenfreesociety.com This site was started by Dr. Peter Osborne, whom is gluten intolerant himself. I find that a doctor who also lives this disease, is much more believeable than those who have no idea what it is all about. Dr. Peter Green, one of the most well known celiac doctors has been heard to say, "If you are not a celiac, then you do not need to be gluten free, and do not make your children live gluten free unless they are celiac too." He has since changed his mind about this and does now recognize that gluten can be an issue for those who are not diagnosed celiacs.
The true test is going gluten free. It seems like a major, very difficult thing to do, but it isn't as bad as it sounds as long as you learn to read labels. Thing is, you have to be totally gluten free to be sure...I advice new people to use gluten free products topically too, you never know if you react in that way too, I do. Tressemme shampoo contains gluten, and when I used it, I broke out in hives...so I always use gluten free products. Aveeno contains oats, I break out in hives, corn products do the same thing to me.
Good luck in whatever you decide, and please, do not expect a hugh change overnite...it takes time for your body to rid itself of gluten poisons.
