Abstract: ObjectiveTo explore the preliminary screening status of mutual voluntary unpaid and relatives mutual platelet apheresis donors, establishing a reasonable apheresis recruitment mode. Methods1,523 cases of platelet apheresis donors&apos; preliminary screening results were collected, among which 714 cases were mutual voluntary unpaid platelet apheresis donors, 809 cases were relative mutual platelet apheresis donors. Preliminary screening results between the two modes were compared from the following 7 aspects: ALT, PLT, RBC count, WBC count, HCT, chyle blood and HBsAg, as well as gender. Then the results were analyzed. ResultsThe overall failure rate of voluntary unpaid blood platelet apheresis donors in the preliminary screening was significantly lower than the relative mutual platelet apheresis donors, the difference was statistically significant (P<0.01) ; ALT, PLT and chyle blood were the highest three. ALT, PLT, chyle blood failure of voluntary unpaid blood platelet apheresis donors were significantly lower than the relative mutual platelet apheresis donors, the difference was statistically significant (P<0.05); male and female failure rate of voluntary unpaid blood platelet apheresis donors were all significantly lower than the relative mutual platelet apheresis donors, the difference was statistically significant (P<0.01) . ConclusionIn all indicators, preliminary screening failure rate of relative mutual platelet apheresis donors is higher than voluntary unpaid blood platelet apheresis donors. ALT, PLT count failure and chyle blood are the main reasons. It is of great significance to expand the team of voluntary unpaid blood platelet apheresis donors and reduce relative mutual platelet apheresis donors for blood donation and supply institutions.
