Regular docs won't test for this stuff because they say it
doesn't indicate a problem although all of the docs I talked to indicated they really had no training in this area.
I went back through the posts and found some of my stuff and Lisa's stuff on the Leaky gut thing and I'll paste it below here.
If these don't post do a search for Great Smokies Diagnostic Laboratories and search around their site
-- there is tons of information on a variety of topics. But I did find some fascinating stuff on Leaky Gut.
