Actually, if you read the Cooperative website, they ARE marketing their test to prostate cancer patients. Yes, this is all a big mess. Cognitive dissonance even when one considers the conflicting results possible for the same test at different labs, Lyme has had this issue for years, and now it appears also XMRV will have that problem. And I did not mean by saying I hoped I had Lyme that I wanted to have Lyme Disease. Rather I was hoping for some treatable explanation for my CFS. I think this is also what XMRV is about right now, people wanting CFS to be something they can treat. When it comes down to it, we should all hope we do not actually have XMRV. Anyway, good luck with that Lyme test, I did have some gains for a time with several of my Lyme treatments but nothing lasted unfortunately. The Lyme community is struggling with the same issue we are, they have a hard time defining the role of co-infections, and I think in reality many Lyme patients that can not progress on treatments actually have CFS with other primary co-infections, probably there is a lot of overlap. Also, there is no proven causal link between XMRV and prostate cancer at this time. In fact the WPI study showed that there is not even a link between XMRV and RNasL status. But I am sure some prostate patients would be curious about an XMRV link and might want to be tested. Incidentally, there is a race right now among several commercial labs, including some BIG ones that are working on XMRV test development right now, to provide affordable blood bank screening for XMRV. A general comment, Cooperative uses a CLIA certified lab for their commercial testing so they are in the same league as VIP Dx. I don't know how many more ways I can say this, I believe the Cooperative test has as much going for it as the WPI/VIP test, for many reasons. The many negatives people are posting here is important data that should be taken seriously and can not be easily explained away.
