BACKGROUND Platelets are routinely stored in plasma for 5 days at an average temperature of 22°C. In the present study, the shelf life of random donor platelets was extended by storing for 7 days with and without additive solution at temperatures of 22°C, 18°C, and 16°C. METHODS Random donor platelets were stored in 100% plasma and 20%/80% platelet additive solution. The data were compared us...
