There is no test for CFS, they have to go off your symptoms. You can be tested for the EBV for Lyme disease and for Mono, those are all pre-CFS. Your Dr. are bouncing you back and forth because that's what having this disease is like, they can't say we are crazy or hypochondriacs anymore but since there's no treatment, they treat us like Lepers. Sorry to sound so pessimistic, the symptoms can be treated, or so I've heard, I'm still trying to find a Dr. who doesn't act like I'm contagious.
