Analysis of characteristics and peripheral blood before blood donation of elderly monoclonal platelet donors
Objective:To analyze the characteristics and the peripheral blood screening before blood donation aged 56-60 in Taizhou area in recent years and provide reference for the health and blood quality safety of elderly blood donors.Methods:The information of blood donors who donated monopectic platelets in Taizhou Blood Cen-ter from July 2019 to June 2023 was collected,and the differences of blood donation frequency,initial screening qualification rate,delayed blood donation rate,two treatment dose donation rate,retest qualification rate and pe-ripheral blood preliminary screening were compared between 56-60 and 18-55 years old.Results:From July 2019 to June 2023,a total of 1 083 platelet donors aged 56-60 in Taizhou donated blood,accounting for 5.2％,and the number of registrations was increasing,while the ratio of men to women was decreasing year by year.The fre-quency of registered blood donation,the ratio of registered male to female,the rate of qualified initial screening and the ratio of blood donation in 56-60 years old were significantly higher than those in the 18-55 years old group(P＜0.05),the rate of delayed blood donation and donation of 2 treatment doses ratio were significantly lower than those in the 18-55 years old group(P＜0.05),and there was no significant difference in the rate of health exami-nation pass and blood retest between the two groups(P＞0.05).The hemoglobin concentration(Hb),hematocrit(HCT),platelets count(PLT)and white blood cells(WBC)of male blood donors aged 56-60 and the PLT and WBC of female blood donors all decreased compared with the group aged 18-55,and the HCT of female blood do-nors was higher.The overall unqualified rate of blood screening in 56-60 years old blood donors was lower(P＜0.05),which was mainly reflected in Hb,HCT,PLT and WBC indexes.Conclusion:The registered number of 56-60 years old platelet donors in Taizhou was increasing,which had the characteristics of high blood donation fre-quency,low blood donation delay rate,a certain degree of decline in peripheral blood image,but the overall fluctu-ation level met the standard and high blood safety.
