Abstract

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.
