ABSTRACT:
A platelet composition suitable for direct transfusion into a patient is provided. The platelet composition includes a preservation medium comprising plasma and a gel-forming material in a concentration relative to the plasma such that the medium is in a sufficiently fluent state at about 37° C. to allow platelets to move within the medium and is in a sufficiently gelatinous state at about 5° C. to substantially prevent platelets from moving freely within the medium; and platelets.
