I had the blood work and it was negative, but I know a lot of people still have negative bloodwork with a gluten intolerance.
have you been tested for celiac disease? i have 3 children with celiac, and one of them was nauseated for months, just shortly after a virus went through the house. We ran all kinds of test to figure out what was going on, and it wasn't until her twin sister developed rahses typical of dermatitis herpetiformis, which is a skin manifestation of celiac, that I suspected celiac.
We tested the one with rashes, the test that was run by the allergist showed damage, but it didn't tell what was causing it. a scope showed reflux and only one area that could possible indicate celiac. we were going to put her onb prevacid for 3 months and run a Ttg blood test, but it was the end of the year, we had met our stop loss, so I had 4 of my children tested to start with---3 of them were positive for celiac---our family haws cooked mostly gluten free for about 7 years now.
We got in on a celiac study, and discovered that my hubby and I and 8 of my 9 children all carry one of the main celiac genes.
