摘　　要：目的探讨单采血小板无偿献血者血液标本放置时间对血常规检测中血小板计数的影响情况,选择合适的检测时间。方法选取单采血小板无偿献血者血常规标本50例,分别于0 h、0.5 h、1 h、3 h、6 h通过sysmex xs-500i血常规仪检测血小板计数。结果在室温条件下,血液标本放置0 h血小板计数偏低为(224.8±16.3)x109/L,与其它各组相比差异具有统计学意义(P<0.05)。0.5-6 h血小板计数较稳定,差异无统计学意义(P>0.05)。结论单采血小板无偿献血者血常规检测血小板计数在标本采集后即刻检测较放置0.5-6 h检测结果偏低,为保证单采血小板质量建议在标本采集后0.5-6 h进行血小板计数。Objective To analyse the effect of specimen storage time on platelet count in apheresis Donors, in order to choose the appropriate testing time. Methods We choose fifty healthy Unpaid Blood Donors of Platelets to test platelet count in 0, 0. 5, 1, 3, 6h respectively by the blood counting instrument. Results At room temperature, the count of platelets from blood samples is relatively lower at 0 hour and the difference is significant （ P 〈 0. 05 ）. After 0.5 - 6 hours, the count of platelets become stabilized and not has significantly different（P〉0. 05）. Conclusion The count of platelets of blood samples is lower at 0 hour than 0. 5-6 hours, this work suggest that the count of platelets of blood samples should be done at O. 5-6 h in order to protect platelets quality.
