question: Hi, I am 38 yrs old male, since last year in every blood count report my WBC count is found lower than the normal limit.  It is in the range of 2500 to 3500.  Last year in Jan 2010 I had severe viral fever for which I was hospitalized for 3 days and since than my WBC counts are found low.  Although I am healthy at present not suffereing from any disease and not on any medication.  In recent health check up my blood report is as under.WBC - 2610, Platlet counts - 135, Hemoglobin - 15.5 g/dl, RBC - 4.93.  What could be the reason for persistent low WBC count and low platlet and what should I do further.  Is this a matter of concern? Pl. advise.
