As a person who underweny colonoscopy and gastroscopy a number of times, I don't think it's so painful. You know what? I even underwent sygmoidoscopy (a test in which they test just the lower parts of the colon) without any sedation or pain management - it wasn't painful (just a little bit uncomfort) and they took 3 biopsies from my stomach - a process that was also not painful and just uncomfortable. I'd undergo it again right now if they would offer me to do this in order to test the samples form XMRV/other MLV-related viruses. And I think that it is a thing that must be done in future studies, because we already know that it's hard to find XMRV in the blood of people, and even in the blood of rhesus macaques that were infected with XMRV - but much easier to find it in other things in the macaques body, like the intestines, including the colon.
** If you are in the serology re-testing program (for previous culture negatives) call VIP to check on your results **
I have called and discovered that my wife's results were available 2 months ago, and VIP did not transmit them to us even though we sent in the fax release to have the results sent directly to us. Moreover, I know of another person who had a similar experience.
The reason why the results often take so long is because they like rechecking the results. This could affect the rate of false positives. On the other hand, no one can accuse them of doing this to make money..
It really was a question for Snow Leopard who specifically asserted that false positives were being produced by VIP dx.
Don't know if they mean a general uncertainty that they fear - it's up to them to answer.
Esther, I'm still waiting for a paper that refutes or disproves or seriously casts doubt on the original Science paper before I judge that things are so uncertain. That's hasn't happened. Do appreciate that others feel differently. I don't think that Lipkin will necessarily clear things up. After all, why make this judgement before we have even seen the paper. I'd rather deal with the known facts.
I think Snow Leopard used the word 'could' which is a fair assumption considering that the more checks made then the less chance of false positives being published. It's only logical considering the XMRV climate to do this.
I noticed what I said was different from what I read here re: my XMRV test results. I had also meant to say I had the blood drawn Nov 23 of last year and just got the results about two weeks ago. Anyway, + for antibodies, neg for culture.
