Hi! Allergy testing won't tell you if you have Celiac but it can help in determining if other foods bother you. That is what I am doing on the 11th. KristaleeJane is right about Celiac testing. Make sure you are consuming enough gluten or you could end up a false negative (that's what happened to me).
I spoke with my doctor today, and he is going to send me to an allergist. He also said he wants to test me (blood tests) for celiac and other food allergies.
Did you get re-tested after your false negative?
