Anyway, if either are low, a biopsy is probably not called for, in my
opinion.  I've seen cases where tTg and anti gliadin antibodies are high,
but the others are low. It could be some other kind of gluten reaction and
not classical CD with villous atrophy,  microscopic colitis for
instance.  Check Dr. Fine's website: www.finerhealth.com for more info.
