just pass on the docs and the tests for right now - it seems as if you have enough information to move forward - just live gluten free for at least 6 months and see where you're at that point -
gluten issues come in all shapes and sizes = certainly one diagnosis does not fit all - just because you test negative for celiac, doesn't mean you don't have a problem with gluten - and maybe some other things -
i had to quit all grains before i found relief - GF was not enough - hopefully you'll be ok with just avoiding gluten - although grain free is not a problem for me -
good luck on your journey !
edit: just read cyclinglady's post = agree with what she said - excepting tor the testing part !
