A misleading headline for a diagnostic test with moderate sensitivity and unstated specificity. I desperately want to believe that chronic fatigue syndrome is as simple as a microbiological imbalance and I hope that we can see some stronger proof but this is an illness that has foxed us for a long time. From UpToDate, my current preferred summary resource (https://www.uptodate.com/contents/clinical-features-and-diagnosis-of-systemic-exertion-intolerance-disease-chronic-fatigue-syndrome https://www.uptodate.com/contents/clinical-features-and-diag... but extortionate subscription required, sorry): "The proposed diagnosis was chronic brucellosis from the 1930s to the 1950s and hypoglycemia from the 1950s to the 1970s. Other hypotheses have included chronic Epstein-Barr virus (EBV) infection [11-13], purported chronic Lyme disease, total allergy syndrome, multiple chemical sensitivity syndrome [14], chronic candidiasis [15], and xenotropic murine leukemia virus-related virus (XMRV) and related retroviruses, such as murine leukemia virus (MLV) [16,17]. None of these etiologic agents have been scientifically linked to the SEID/CFS." Extraordinary claims require extraordinary evidence.
