Abstract
A method for processing a biological fluid comprises the steps of collecting platelet-rich plasma (PRP) in a container containing a complement filter, centrifuging the PRP in the container to provide a supernatant layer comprising a volume of platelet-poor plasma (PPP) and a sediment layer including concentrated platelets, passing most of the volume of the PPP from the container, suspending the platelets in the remaining volume of PPP to provide a platelet suspension and storing the platelet suspension in the container for a storage period of at least about 24 hours while contacting the complement filter with at least a portion of the platelet suspension and removing complement from the platelet suspension.
