<<Disclaimer: Verify this information before applying it to your situation.>> When is it too late for a celiac blood test? Three months ago in a self-help health attempt we put my mom on a rotation diet to uncover food addictions from among her frequently eaten foods. After eliminating irritants she is now better but thinner on a non-gluten, non-milk, non-a lot of other stuff diet. We have learned more about food families and hidden ingredients and in a shorter time than we ever wanted to. But we are getting into the swing of it. (It is only the addictive form of the allergy that is new to us. Our family has had much experience with the reactive type of allergy from hayfever to food to contact dermititis to sunlight photosensitivity.) Now we understand from this group that the situation is more serious than simply allergies. Is gluten testing worthwhile at this stage? How can it show anything since she has stopped eating gluten, aside from some setbacks? We want to make an informed request to her doctor, not just ask to start a round of tests.
