献血者血常规指标及生理状况对机采血小板质量的影响

目的观察机采血小板的收集与献血者采前外周血血常规的几项指标和自身生理状况的相关性。方法对采血前、后血小板（PLT）计数等进行分组分析。结果血小板机采量与采前PLT计数呈正相关系（r=0.488）,并与献血者的年龄和体重有关（r值分别为0.206和0.273）。结论采血前外周血血常规的指标和自身生理状况均对机采血小板的收集量有一定的影响。为了进一步提高机采血小板的收集量,保证血小板的质量,机采前必须严格筛查献血者。

Effect of Blood Routine Indexes and Physiological Conditions of Blood Donors on Apheresis Platelet Quality

[ Objective] To observe the correlation between the collection of apberesis platelet, indexes of donors＇ peripheral blood before blood donation and their physiological conditions. [ Methods ] Platelet counts （ PLT） were analyzed in group mode before and after blood donation. [ Results] Apheresis platelet volume positively related with PLT before blood donation （r =0.488） , and related with the donor＇s age （ r = 0.206 ） and weight （ r = 0.273 ）. [ Conclusion ] Indexes of donors＇ peripheral blood and their physiological conditions have a certain effect on apheresis platelet collection. In order to improve the collection volume and ensure the collection quality, the blood donor should be strictly screened before donation.
