While this research is interesting, I'm not sure it quite lives up to the hype of the press releases. There have been quite a few other studies showing potential biomarkers, for example: the cortisol awakening response with respect to ground, and repeat cardiopulmonary tests. In fact, I suspect these other tests might be more useful, as they may identify all patients rather than just ones that have been ill for less than 3 years (although more research is needed).
