Thanks, TSandM. I'd like to expand upon your comment.
The Centers for Disease Control and Prevention (CDC) states: "A number of factors add to the complexity of making a CFS diagnosis: 1) there is no diagnostic laboratory test or biomarker for CFS; 2) ...."
http://www.cdc.gov/cfs/cfsdiagnosis.htm#challenges
The Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS) Association of America states: "As yet, there is no indicator or diagnostic test that can clearly identify the disorder."
http://www.cfids.org/about-cfids/diagnosis.asp
The Mayo Clinic states: "There's no diagnostic or laboratory procedure to confirm the presence of chronic fatigue syndrome."
http://www.mayoclinic.com/health/chronic-fatigue-syndrome/DS00395/DSECTION=6
What these very authoritative sources are saying is that immuno, enzymatic and other assays, such as those offered by Redlabs USA, are NOT confirmatory of chronic fatigue syndrome (CFS).
Moreover, it doesn't even appear that Redlabs USA itself asserts that their procedures "confirm" CFS. Rather, Redlabs USA says they have been able to create a number of lab tests that "can assist" the physician in making the diagnosis of CFS (
http://www.redlabsusa.com/chronicfatiguesyndrome.htm).
A second point is that if there were blood tests that confirmed CFS, or any disease subset thereof, they wouldn't be available only from ONE facility based in Northern Nevada that has corporate parentage in Belgium. The tests also would be available at major medical centers/diagnostic labs, particularly those with an interest in CFS.
Recognized and reputable authorities agree that the diagnosis of CFS can only be made by a lengthy, time-comsuming and challenging process of excluding other illnesses with similar signs and symptoms and comparing the patient's features with the currently agreed upon case definition.
