ABSTRACT:
Systems and methods obtain a platelet suspension with reduced number of leukocytes by centrifugally separating whole blood into red blood cells, a suspension of platelets, and an intermediate layer comprising leukocytes. The systems and methods convey the suspension of platelets from the centrifugal separation chamber to a filter, while maintaining the intermediate layer containing leukocytes inside the centrifugal separation chamber. The systems and methods filter remaining leukocytes from the platelet suspension in the filter.
