A colleague of mine who has some experience in the area says, You cannot use cell surface markers to diagnose CFS, or to make any clinical judgement. You can look at subsets for research studies, and then it's really up to the researcher to decide on the panels, based on the data (of which Landay's paper is certainly a good, though not the only, source). However, some companies offer panels, as far as I can tell, just to make money. They also offer NK function tests, which tell you nothing about the disease. >From what I've seen, this testing is a can of worms. I hope you are not charging the patients for this fishing trip.
