Factors influencing yield of plateletpheresis by discontinuous centrifugation.


Plateletphereses performed by the Haemonetics Model 30 Blood Processor under a fixed condition were retrospectively analyzed. The mean platelet yield was 5.97 X l0 (ll) (+/- l.46 X l0 (ll). Prepheresis platelet count was significantly correlated to platelet yield (p less than 0.001), but hematocrit was not (p greater than 0.1). Blood-drawing time showed a… (More)
