Hi RedFox, have you watched this video on gluten sensitivity? http://www.glutenfreesociety.org/video-tutorial/gluten-sensitivity-what-is-it/RedFox said:In the end he referred me to the 'gut' (can't spell the proper medical word for this type of doctor!) expert....which I would hear from in 3-4weeks....they will probably be testing for celiac disease (I told him I hadn't eaten wheat for 2 years!), probably by getting me to eat wheat and then taking a biopsy (this isn't confirmed yet).
Dr. Osborne talks about biopsies and tests for gluten sensitivity. It seems biopsies aren't necessarily that accurate (he mentions one woman who had several, and only the last one turned out to be positive). He recommends genetic testing. It's kind of expensive (over $300), but apparently it's really accurate.
