Lieve Allemaal,
Ik las net op
http://aboutmecfs.org/Rsrch/XMRVBuzz.aspx, het nieuws dat een aantal onderzoekers naar aanleiding van de eerste testresultaten het idee hebben dat de serologie meer positieven oppikt dan PCR (alleen). Interessant voor diegenen die negatief testen op de PCR en wellicht overwegen alsnog de serologie te doen, of diegenen die in verband met kosten proberen een keuze te maken welke (eerst) te doen.

Dr. Cheney Reports - in his latest newsletter - or at least that part of which is available for free - Dr. Cheney reports news on the serology tests emanating from VIP Dx. Earlier Dr. Mikovits noted that antibody tests picked up more positives than PCR tests.
Dr. Cheney noted that 2 out of the three people who tested negative by PCR later tested positive by antibody tests. Overall 83% of his 47 patients have tested positive. He expects the percentage to rise to 90% when all the serology results are in - putting the number right about where Annette Whittemore suggested when XMRV broke. It appears from his numbers that the antibody test may add maybe another 10-15% to the percentage of positives.
Rather startlingly Dr. Cheney reports that 60% of family members without CFS also tested positive but the numbers tested were very low (10 ) and therefore could change dramatically. Nevertheless, if they are ultimately validated, they would indicate that XMRV is quite infectious - not a surprising finding given the mostly anecdotal evidence to date; XMRV appears to be a more robust virus than HIV and may be able to survive in the saliva and semen and cervical fluid.
