Having published, last month, in PloS One, that a study led by Prof Myra McClure (Imperial College London) and Prof Simon Wessely (King’s College London) found no evidence that XMRV is associated with CFS in the UK, Imperial College London is now offering a £200 XMRV test.

Imperial College London XMRV Detection testing

Scope of the test

Infection with the newly discovered retrovirus xenotropic murine leukaemia virus-related virus (XMRV) has been associated with prostate cancer [1, 2] and chronic fatigue syndrome (CFS) [3]. No causal link between infection and any human disease has been proven and the association between XMRV and prostate cancer or CFS remains controversial [4-6]. Indeed, in a study in our own laboratory of 186 patients with well-defined CFS we failed to detect the virus in any sample [7].

Test details

The test uses the polymerase chain reaction (PCR) to detect XMRV provirus (the DNA form of the viral genome) in peripheral blood mononuclear cells. The limit of detection of the method is one XMRV proviral DNA copy in 105 cells. The test includes controls for non-specific inhibition of PCR to avoid false negative results. The method is a fully validated in-house method. A summary of the validation is available from the Unit Manager.

Reporting results

The results will be reported as “XMRV detected” or “XMRV not detected”, the test is not quantitative at present.

Turnaround time

We aim to issue reports within two weeks of receiving a sample. Details of samples and sample shipment are given on the user instruction page [weblink]. Please note we can only accept test requests and samples from medical practitioners (GPs or hospital doctors) we will not accept test requests directly from patients.

Charges

The current charge for testing is £200/sample.

Complaints

If you are unhappy with the service provided by MDU or if you wish to make suggestions on how our service can be improved, please contact the Unit Manager.
