Im wanting to hear the answer to my question "Is low white blood cell count normal in XMRV?" in those who have been diagnosed XMRV positive. How long have you had CFS/ME and what is your white cell count like? Im yet to be able to get tested for XMRV but over the years my white blood cell count has been falling and now it is out of normal range and low. at 3.5 (normal is 4 to 11) http://www.forums.aboutmecfs.org/sh...ally-low-white-cell-count&p=113440#post113440 has the details of how it has fallen over the years.
