The purpose of this research was to study the variance in recommended storage temperature for platelets and to provide proper protection during transit. Tests were conducted in an environmental chamber designed to provide constant temperature with plus or minus .01 F fluctuation. An eleven-channel scanning telethermometer was used to measure temperature of the 25 ml aliquots of platelet-rich plasma. Platelet aggregation occurs at low temperatures even with agitation however, aggregation is not considered to be a reliable means of measuring viability. Nevertheless, the degree of effectiveness of transfused platelets to improve hemostasis is dependent on their ability to circulate in the recipient. Consequently, investigators recommended different temperatures for processing and preparing platelets for storage based on a particular phase of the processing procedure. The real need for establishing a standard criterion for determining platelet viability is evidenced by the variance in temperatures recommended. Data are submitted describing packaging techniques which will provide maximum protection for platelets during transit based on the particular processing procedure used.
