I had the Great Smokies and the Great Plains test. The Smokies test was a stool test and the Plains test was a urine test. The stool test only came up with elevated estrogen but the urine test came up with the Arabinose and an anerobic bacteria. Yes I've done cleanses and colonics. I'm doing now what I was afraid to do before taking herbs that kill infection. I had read too many things saying that if you kill off things they just grow more resistant. But my DR/Naturopath explained to me that the arabinose and bacteria were found in my small intestines. It is much more difficult for medications and other treatments to reach the small intestines. He has me on a regiment that is specifically designed to work together to reach the small intestines. It is important that I get the bacteria under control because it is causing the elevated estrogen levels which is precancerous. It is a good thing I got tested or I would have never guessed about the estrogen or known of it's danger.
