AB Random  donor  platelets  are  prepared  by  centrifugation  techniques  that  yield  from  7  to  10  ×  1010  platelets  per  unit  of  blood.Platelets  so  obtained  are  suspended  in  citrated  autologous  plasma  and  are  significantly  contaminated  with  leukocytes.  Several  units  of  platelets  are  pooled  to  provide  sufficient  platelets  for  transfusion  (4–6  U  for  an  adult).Single-donor  platelets  are  prepared  from  a  single  individual  by  plateletpheresis.  Each  plateletpheresis  contains  approximately  3  to  4  ×  1011  platelets,  significantly  contaminated  with  leukocytes,  although  more  modern  apheresis  machines  markedly  reduce  the  level  of  white  cell  contamination  in  platelet  concentrate.Fresh  whole  blood  is  used  for  platelet  transfusion  in  children  younger  than  2  years  of  age  who  have  undergone  open  heart  surgery.
