<<Disclaimer: Verify this information before applying it to your situation.>> Many, many thanks to those who sent useful information. And a please, no more, to some other folks. Just a point about going gf before the testing: (this was someone's concern that I had put my son on the diet rather than stuffing him with bread). The first thing that the naturopath did, before the serious evaluation, was to put me on a really annoying diet. For over a month, I ate steamed vegetables & some brown rice, and a nutrient drink/"cleanser" that just so happened to be gf. _Then_ I was given the Adrenal Stress Index I had a copy of the lab report sent to my home address. Instructions on dealing with what was obviously celiac disease were printed up with the report. If I still tested positive after a month of that diet, I really don't think a couple of weeks of no wheat is going to affect testing signifigantly. Ellen Gold
