And yes--
--low total IgA can skew the results of the anti-transglutaminase IgA test for celiac, most often in a false negative direction.
You may have to go for the gold standard--endoscopic intestinal biopsy to search for atrophied villi. Just make sure it is done at a place familiar with the protocol at which they will take many samples from many different parts of the intestine, not just one of two--especially in the early stages damage from celiac can be patchy.
