Thanx to those who responsded.  I only received 3 responses on this subject,
so here they are:

My doctor referred me to the Great Smokies Lab in North Carolina, and gave
me a testing kit.  I drank some liquid after being on a particular diet for
a while, I don't remember how long, and then prepared urine samples
according to their directions, and sent them by Fed-Ex overnight to the lab.
Anyway, it's called a test for intestinal permeability.  There is a website
that explains the test.  If you haven't already received that info, I can
pull it from my files and forward it to you.

I've not had this done, but you might find this article interesting.

By the way, if you have celiac disease or any food allergy, you certainly
have leaky gut too. They form a vicious cycle together.

I was diagnosed with the Great Smokies Intestinal Permeability Test that my
doctor ordered.
