All testing either measures the antibodies produced by the inflammation in the small bowel lining produced by gluten consumption or looks for the damage the to that lining that the inflammation causes. If you take away the gluten, the inflammation subsides and so do the antibodies and healing takes place such that there is no damage to see.
