Chronic Fatigue Syndrome stops people from donating blood, a rule that exists in Canada and Australia and New Zealand is ready too, to follow the footsteps of its counterparts.

The reason that these nations have taken up this decision is that there is a relation between CFS and definite retrovirus.

The link however between CFS & XMRV is not chiefly precise. A study in Nevada found that 60% of CFS sufferers, N=101, which also had traces of XMRV in their blood, as contrasted with <4% of healthy controls, N=218.

It would be important to note that samples that had been tested came from individuals with CFS, who may have lived where XMRV is quite commonly found.

It can be understood that the Blood Service has been wanting to err on the side of watchfulness, given issues with impure blood in the past the Hep C/haemophilia problem, for instance.

As a result, it may be said that it probably is better to be safe than regretful. A prohibition can always be upturned if the evident XMRV-CFS link turns out to be non-existent in the end.

A commercial test for XMRV is at present available. After seeing this one draws an expectation to see if something positive coming out, indeed.
