I think that the most significant finding here is the small intestine and large intestine inflammation. The gut bacteria mentioned are opportunists, not pathogens but they do overgrow when the person has an underlying intestinal problem. You probably do not have an autoimmune gluten (glaidin)problem but it does not rule out a non-autoimmune gluten intolerance or a less common food allergy. Even tho 3 stool samples were tested it does not rule our all parasites as only a few were looked for and some would not be in the stool.
Other than returning to your Dr for more tests you could look at the programs on the Liver Flush Support Forum
. This will give you an overview of the types of programs that will improve your digestive health.
Thanks for posting your results. I have not seen a DiagnosTech report before tho many people have found it helpful.
