Biological Markers in ME/CFS

I have come across some interesting articles on ME. The first page deals with physical biological tests that can be done to diagnose ME and to differentiate it from other fatiguing illnesses. I'll post a paragraph and the URL.

“Unlike somatization disorder, ME is not ‘medically unexplained.’ ME is a disease which, like lupus, has no single marker. ME is a multi-system disease with many organ and bodily systems affected, producing a myriad of symptoms, and many aspects of the pathophysiology of the disease have, indeed, been medically explained in volumes of research. These are well-documented, scientifically sound explanations for why patients are often bedridden and unable to maintain an upright posture.”
