<p>Platelet rich plasma and/or platelet concentrate is prepared by placing whole blood in a first chamber (6) of a sterile processing disposable having two chambers (6, 8). The processing disposable is subjected to a first centrifugation to separate red blood cells (36), and the resulting platelet rich plasma supernatant (38) is decanted to the second chamber (8). The processing disposable is subjected to a second centrifugation to concentrate platelets. A volume of the platelet poor plasma supernatant in the second chamber (8) is removed, and the platelets are re-suspended in the remaining plasma. The second chamber (8) may contain anticoagulant (34) to preclude aggregation of the platelets.</p> |
