Abstract
A blood component collection system and method each utilizes centrifugation to first separate whole blood into red blood cells and platelet-rich plasma. Noncentrifugal separation is then utilized to further separate the platelet-rich plasma into platelet concentrate and plasma which is virtually free of platelets. The system and method are applicable for use in association with both batch and continuous flow procedures.
