Abstract
OBJECTIVES: This study aimed to investigate the changes of platelet (PLT) function and coagulation time before and after plateletpheresis donation. MATERIAL AND METHODS: The healthy donors were divided into four groups according to the annual number of plateletpheresis donation: 20 times group, 15 times group, 10 times group and 5 times group. The healthy non-blood donors were selected as controls. The donation interval was 14 days. The blood samples were collected before plateletpheresis donation and after 30min, 7 d, and 14 d of donation for determination of coagulation time, PLT function, plasma protein, serum iron and blood routine change. RESULTS: After 30min of plateletpheresis donation, the PLT function decreased and the coagulation time was prolonged. However, PLT function recovered to the pre-collection after 7 d of plateletpheresis donation and coagulation time recovered to the pre-collection after 14 d of plateletpheresis donation. Additionally, there was no difference regarding blood coagulation time and PLT function among blood donors and controls. The plasma protein and serum iron levels in 20 times and 15 times groups were within the normal reference range. CONCLUSION: The frequency of plateletpheresis donation will not affect PLT function, coagulation time, plasma protein and serum iron in donors.
