ABSTRACT:
A method for preparing platelets comprises the steps of obtaining whole blood from human, preparing platelet rich plasma from the whole blood and then passing the platelet rich plasma through a filter comprising a porous medium having a CWST of at least about 70 dynes/cm, under conditions sufficient to remove in excess of about 99.99% of the leucocytes from the platelet rich plasma, with preparing platelet rich plasma and passing the platelet rich plasma through the filter occurring in an integrally-attached blood bag system within a few hours of obtaining whole blood from human.
