Amy has blogged about the upcoming XMRV Working Group Report to the FDA.
In this phase, six labs — two from FDA plus labs at the NCI, the CDC, the Blood Systems Research Institute and the Whittemore-Peterson Institute — used a panel of blood samples spiked with different amounts of XMRV to establish if the labs’ tests are sensitive and reliable enough to detect the virus in blood. They are. All the labs were able to detect at least some amount of XMRV. (Some of the labs have been involved in the dueling research on a link between the virus and CFS.)
As researchers continue to study XMRV, there is a growing sense that virus taken from patients may be different than the virus the labs studied. That’s why, researchers say, it’s important to start looking at what’s going on in actual people.
