Im wondering if I should be worrying about my latest blood test results or not. My white blood count seems to be taking a dive and now abnormal. My white blood cell count has slowly fallen over the years I've had CFS/ME. (norma range for WBC is 4 to 11) my results have been: 1998- 5.5 (after 1-2 yeas of CFS) 2005 - 5.4 2006 -4.3 2007 - 4.1 2008 - 4 (right on border of normal range) 2010 - 3.5 (below normal) Im right now a bit concerned.. none of my doctors seem to be worried of my falling white blood cell count over the years and now that its abnormally low. I realise the white blood cells are our defence against viruses, bacteria etc (and also have read that this white blood cell count falls in conditions such as leukemia and is an early warning of it). im sure thou my issue is being caused by my body fighting a chronic virus. .......... Is anyone who is XMRV positive.. have out of range low white cell counts?? Is this normal for that??
