ABSTRACT
Objective To evaluate the quality of pooled platelets leukocytes reduced after filtering out leukocytes using two man-ufacturers of leucocyte filters for pooled platelets and improving the preparation method.Methods Pooled platelets was prepared from 400 mL fresh whole blood by buffy coats(BC)method,after 1 6 h,(22±2)℃ holding period,pooled six bags of ABO-matched buffy coats.and then filtered with two manufacturers of leucocyte filter,divided into the control group and the experimental group. Before and after filtering,the numbers of platelet and leukocyte,pH,hypotonic shock response(HSR),platelet aggregation and CD62p expression were detected.Results Before filtering leukocytes,the platelet quality of two groups achieved the requirements of Chinese standards.The numbers of platelet and leukocyte,pH,CD62p expression(%)and platelet aggregation showed no signifi-cant difference between two groups(P >0.05).However,After filtering,the pH,platelet aggregation and the platelet recovery,the experimental group and the control group,were (6.53±0.60)vs(7.00±0.06)、(5.5±3.8)% vs (77.4±14.7)%,(86.8±4.3)%vs (90.6±2.7)%,showed significant differences (P 0.05).Conclusion The quality of pooled platelets leukocytes is reduced,after filte-ring out leukocytes with two manufacturers of leucocyte filters and improving the preparation method,achieves the requirements of Chinese standards.However,the leukocyte filters of experimental group might have influence on platelet aggregation and pH.
