The reason I ask is because its kinda tough for me to know when I am glutened since I dont react to anything at all. The tests say I have it but I would never know it if I ate a regular piece of pizza or bread. I wouldn't do that but just giving an example.
Yes, that would be tough. I would think regular follow-ups with your GI for blood tests would be sufficient to make sure your numbers stay in the normal range and you are not accidentally getting glutened on a regular basis.
