<<Disclaimer: Verify this information before applying it to your situation.>> Sometime in the past few months I read on the list about an alternate way to test people who had been on a gluten free diet. Instead of having to challenge the system with a gluten diet over several weeks, a gluten containing suppository was used, and the person was tested several hours later. I do not recall in which country this was used. Unfortunately, I did not save the article, but would be most interested in obtaining it again if anyone can help.
