AB In  most  automated  instruments  that  count  cells  in  the  blood,  the  red  blood  cells,  the  white  blood  cells,  and  the  platelets  are  counted  by  an  electrical  impedance  method.  In  addition,  hemoglobin  is  measured  directly  from  the  whole  blood  specimen  after  lysis  of  the  red  blood  cells.  There  are  many  other  parameters  in  an  automated  blood  cell  count,  which  are  calculated,  based  upon  the  data  obtained  from  the  direct  cell  counts  and  the  hemoglobin  value.  Calculated  parameters  include  the  hematocrit,  red  blood  cell  count,  the  mean  corpuscular  volume  (MCV),  the  mean  corpuscular  hemoglobin  (MCH),  the  mean  corpuscular  hemoglobin  concentration  (MCHC)  of  red  blood  cells,  and  the  mean  platelet  volume  (MPV).  The  white  blood  cell  differential  count  is  obtained  after  lysis  of  erythrocytes,  using  flow  cytometric  technology  to  identify  size,  shape,  and  granularity  of  the  cells  which  permits  identification  of  the  individual  white  blood  cell  populations.
