RESUMEN
【Objective】 To investigate the age, gender and unqualified blood test of voluntary blood donors, so as to provide a data support for blood donation publicity, recruitment and retainment of blood donors, and to avoid unnecessary waste of blood resources. 【Methods】 The age, gender and unqualified blood test of voluntary blood donors in Lianyungang area from 2017 to 2020 were retrospectively classified and statistically analyzed. 【Results】 The proportion of voluntary blood donors increased with age, and the proportion of blood donation in the 51-60 age group decreased. The unqualified rate of voluntary blood donors showed a downward trend with the increase of age. The unqualified rate of blood test in 51-60 age group was rather low. Except for 18-20 age group, the blood donation ratio and the unqualified rate of blood test of male blood donors in all age groups were higher than those of female blood donors, which were 1.47∶1 and 1.30∶1, respectively. The total unqualified rate of blood test was 1.09%(1 274/117 079), and it decreased year by year. The unqualified item of blood test was ALT>HBV>TP>HCV>HIV, and the unqualified rate of ALT test between male and female blood donors was significantly different(P<0. 05), and the unqualified rate of HBV and TP test in different time periods was significantly different(P<0.05). 【Conclusion】 The publicity of voluntary blood donation for people aged 18-25 and 50-60 should be strengthened, and regular blood donor team should be continuously retained and expanded. Effective consultation and preliminary blood screening before blood donation are of great significance in reducing the unqualified rate of blood test. The unqualified rate of HBV and TP tests can be reduced by scientific preliminary screening process and standardized operation, which is of great significance to reduce the waste of blood resources and ensure blood safety.
