ABSTRACT

BACKGROUND:

Effects of storage period on platelet activation of random-donor platelets (RDP) prepared from whole blood units and single-donor platelets (SDP) prepared from single-donor apheresis collections have been investigated in this study. We also analyzed the correlation between amount of blood cells and platelet activation in random-donor platelets.

METHODS:

RDP and SDP were collected at 1 day, 3 day, or 5 day during storage. In case of SDP, whole blood was also collected just before apheresis. The platelet activation in RDP and SDP was measured by flowcytometry using monoclonal antibodies against CD41a, CD61 and CD62p.

RESULTS:

In SDP, MCFI against CD62p has been significantly increased during storage and any significant differences are not found according to the kinds of pheresis machines. In RDP, no significant differences in MCFI against CD62p were found with storage period and showed a increased MCFI dependent only on the number of platelets.

CONCLUSION:

Single-donor platelets should be used as soon as possible for transfusion due to progressive platelet activation with storage period. On the other hand, a proper number of platelets should be maintained under strict quality control system to minimize platelet activation in RDP.
