My son was diagnosed with celiac 3 years ago. We (immediate family) were all tested and came up negative. The specialist he went to said all immediate family members should be retested every 2-3 years.
Since we made the whole house gluten-free, none of the non-celiacs in the family each much gluten. Thus, in order to get re-tested, we need to eat some.
Does anyone know what the current recommendations are for a gluten challenge? I've seen everything from 4 pieces of bread for 6 weeks to a couple of crackers a day for 12 weeks. Nobody will likely get sick doing this, so we don't need the bare minimum, but since all gluten is eaten outside the home, I don't really want to have to stuff 4 slices of bread in me every day at work if I don't have to.
Also - when we were originally tested, the doctor ran total IGA and ttg IGA. Do we need both again? Or is just ttg IGA enough? (Total IGA #s were normal for everyone last time.)
