Results of blind panel testing. Results of blind panel testing. Blood was collected from four patients with CFS found to be XMRV positive in the 2009 Whittemore Peterson Institute (WPI) study published in Science, as well as XMRV/MRV-negative controls. Specimen tubes were then divided into three groups, with one set immediately processed into peripheral blood mononuclear cells (PBMC), whole blood, and plasma, while the other two sets were refrigerated and then similarly processed after 2 and 4 days. These samples were coded, blinded, and distributed to three laboratories—the CDC, the National Cancer Institute (NCI), and the WPI, as well as to GenProbe. False-positive results were reported by the Whittemore Peterson Institute (Lombardi) laboratory. DRP, HIV Dynamics and Replication Program. (Based on data from reference 45.)‏ Andrew D.
