1. A method for preserving platelets for later direct transfusion into a patient, the method comprising:forming a preservation medium by mixing plasma comprising platelets with gelatin where a concentration of gelatin relative to the plasma in the resulting preservation medium is between 1.0% to 3.0%, this gelatin concentration causing the preservation medium to (a) be sufficiently fluent at about 37.degree. C. to allow platelets to move within the preservation medium, (b) transition from the fluent state to a gelatinous state below 15.degree. C., and (c) be sufficiently gelatinous below 5.degree. C. to substantially prevent platelets from moving freely within the preservation medium; cooling the preservation medium to a temperature below 0.degree. C.; and storing the preservation medium below 0.degree. C. for at least 1 day at a pressure of at least 70 ATM.
