In Vitro Infidelium
Lombardi claimed they were clinically validated,although I have no idea what "internally" is supposed to mean:
“The “XMRV test” offered by VIP Dx is clinically validated and performed under rigorous protocols to ensure the accuracy and reliability of the test results. XMRV testing was offered based upon the existing scientific knowledge at the time. The original assays for XMRV testing were based on the 2009 Science publication. Those assays, as well as all subsequent modifications, were internally validated prior to being used to process patients’ samples.“
(Statement of Vincent Lombardi, Phd, Clinical Lab Director, VIP Dx, 14 October 2011) (11)
The difficulty with that statement is that it was made after sale of the tests were suspended (and indeed possibly after Redlabs ceased trading), so (apart from the ESME page quoted already) there is no public record of what was being claimed for the tests by VIPdx at the time tests were being promoted to patients.
