Thanks for all the good info! Now I just have to get brave enough to give them to my son.

RathyKay, you bring up a good point about waiting until after any testing. I am considering doing the Enterolab soy test and maybe the gene test. We've been gf so long (and dairy-free, egg-free even longer), that I don't think there's any point in testing for those. But I now have my son off of soy and corn too and have had for over two months. I wonder if it (soy) can still be detected (I know Enterolab says gluten can be detected for over a year)...
