Old blood: Are - XMRV research participants really +?

Hi everyone, here's the thought of the day............

By scientists using 'old CFS blood' (not fresh samples) these archived blood CFS patients who are XMRV negative in studies they enter, they can not tell the media they are indeed XMRV positive by Culture/Antibody if getting tested at VIPDX behind the researchers back.

Scientists in the study, could argue the now XMRV+ CFS patient who goes to the media, actually got infected since the 15yrs old blood was taken, hiding the inabilty of their test to work...........Covering Groom, Kuppeveld, Wessely/McClure's & Switzer's back.......and meaning the participant in the study hasn't a leg to stand on if accusing them of foul play.

Ever thought about that? No way of proving now and the 'failed' XMRV studies stand.

NB: Alter/Lo FDA study, to my knowledge used archived blood of CFS patients and then compared this to fresh samples of the same CFS patients so Alter/Lo isn't included here obviously.

Unless for honest reasons that Alter/Lo used, the use of old blood risks the sample degrading, including the virus.

When they used fresh blood from 8 patients they did not find XMRV at all but did find the other MLVs in seven of the samples--just like the "old blood".
