ABSTRACT:
Systems and methods separate whole blood containing leukocytes in a first separation chamber into a first layer comprising red blood cells, a second layer comprising a suspension of platelets, and an interface between the first and second layers. The systems and methods convey the suspension of platelets into a second separation chamber while simultaneously filtering the suspension of platelets to reduce the number of leukocytes. The systems and methods separate the filtered suspension of platelets in the second separation chamber into a platelet-rich concentrate and platelet-poor component.
