I have been asked by a GP with a patient who has CFS about the value of, the accuracy of, the following tests, and if they reflect what they are claimed to do. I can find no peer reviewed strong evidence for the usefulness of any of them, and wondered if there is a colleague out there with more knowlegde they are able to provide about these "fringe" tests. I have informed the GP of my reservations/concerns, so any useful information would be welcomed by us both.
