Interruption of agitation of platelet concentrates: a multicenter in vitro study by the BEST Collaborative on the effects of shipping platelets

Abstract

PLTs in plasma shipped for at least 20 to 24 hours maintain a pH(22 degrees C) value of 6.5 for 7 days. A longer shipping time may result in a pH(22 degrees C) value of 6.5. During shipping, glycolysis was up regulated in these PLTs resulting in increased lactic acid production. After restoration of agitation, shipped products down regulated glycolysis. These effects should be accounted for in the development of PLT storage and transportation systems.
