摘要
目的探讨机采血小板检测前过程的质量控制。方法留取机采单份血小板、机采双份血小板样本各100份,以1∶1、1∶3及1∶7稀释度进行稀释,采用全自动血液细胞计数仪检测血小板计数。另采集机采血小板样本100份,室温下静置0、30、60、90、120min,以1∶3稀释后,检测其血小板计数。结果机采单份或双份血小板样本以1∶1与1∶3稀释后检测血小板计数的差异及1∶3与1∶7稀释后检测的差异均有统计学意义(P<0.05)。静置0、30min检测的血小板计数与静置60、90、120min的检测值的差异有统计学意义(P<0.05)。结论机采血小板检测前过程的质量控制对采集后的血小板计数十分重要。
Objective To study the quality control of previous process of apheresis platelets detection .Methods Single and double apheresis platelets each of 100 samples were collected and were diluted 1∶1 ,1∶3 and 1∶7 .Aautomatic Blood Cell Count-er was employed to detect the platelet count .Another 100 samples of apheresis platelets were collected and stand at room tempera-ture for 0 ,30 ,60 ,90 ,120 min ,After 1∶3 dilution ,the platelet counts were detected .Results Differences of platelet counts be-tween 1∶1 and 1∶3 dilution ,1∶3 and 1∶7 dilution of single or double apheresis platelets showed statistically significant differ-ences（P〈0 .05） .Differences of platelet counts between standing for 0 ,30 min and standing for 60 ,90 ,120 min were found statis-tically significant（P〈0 .05） .Conclusion Quality control of previous process of apheresis platelets detection is very important for platelet count after collection .
