My son tested negative for celiac at 9 months. He's now 12 months old and we've been wheat/gluten free for nearly 8 months or longer. However, he also reacts badly to dairy, soy, corn, egg, citrus, tomato, tree nuts, peanuts, strawberry, chocolate... He's exclusively breastfed, so it's through my diet that I measure the changes in his behavior, spitup, excema and stool/rashes. I feel pretty certain the test is worthless at this age as are allergy tests judging from our homework here.
