摘要：
A method provides for procuring platelet rich plasma (PRP) from a sample of whole blood in a vial. The method includes the steps of: separating the whole blood into layers through centrifugation with an upper layer containing platelet poor plasma (PPP) and a PRP layer below the upper layer containing PRP； adjusting an end point of a first range of motion of an extractor relative to a position of the PRP layer； moving the extractor through the first range of motion through the vial, PPP passing out from the upper layer through the extractor； and after the extractor reaches the end point of the first range of motion, extracting the PRP through the extractor and collecting the PRP.
