The posting by the patient about the response to a gfd and then getting
tested points out the difficulty in making the diagnosis after a gfd has
been started. I believe( based on seeing many people with suspected
celiac disease) that it is really important to get tested for CD BEFORE
going on a gfd. It is hard to interpret the biopsy the blood tests are
unreliable and the patients are often faced with the very unpleasant
task of a prolonged gluten challenge to verify diagnosis.
