thanks for the reply,

I have stopped eating gluten, but haven't felt much better. I'm not sure if I should start eating gluten again for the test? My doc didn't tell me too. I would have thought that if I have effected intestines by gluten then they won't heal in a month or so time, so should still get a positive result.

My main reason why I don't think I have intestine probs due to gluten is that the other antibody tests came back negative.

Will see once the test gets done anyway.
