Hello, I want to start a 4R protocol in order to fix my gut issues first. I understand that for testing purposes, the recommended ones are the CSA, the Metametrix GI, and for leaky gut, the one from Genova Diagnostics. I'd like to know whether these tests are available for people from abroad. I am located in South America. In the meanwhile I got in touch with people from greatplainslaboratory.com which have contacts with doctors in my country, mainly professionals treating autism. Any references from this laboratory? Do you think they are able to practice equivalent tests to the other ones? Thanks!
