Retrospective Analysis of Blood Test Results of Volunteer Blood Donors
Objective:To analyze the results of unqualified blood screening among blood donors in Shaoxing region.Methods:257 145 blood samples from volunteer blood donors from 2017 to 2021 were tested for HBsAg,HCV,HIV,TP,ALT,HTLV,and NAT.All blood test results were analyzed retrospectively.Results:Over the 5-year period,the average failure rate of the tests for volunteer blood donors was 1.22％.In the descending order from high to low,the positive rates of ALT,HBsAg,NAT,TP,HCV,HIV,HTLV were 0.32％,0.25％,0.20％,0.19％,0.17％,0.07％,and 0.01％respecitively.Of these,HBsAg(x2=65.23),ALT(x2=47.32),and HCV(x2=12.73)were significantly different between different years(P＜0.05),but TP(x2=4.19),HIV(x2=7.58),NAT(x2=7.62),and HTLV(x2=6.75)were no significant differences(P＞0.05).And the positivity rates of HBsAg and HCV was a trend of decreasing.By comparing nucleic acid and enzyme immunoassay positive tests,the two methods were found to complement each other.The age and gender distribution difference of the positive population could help to better ensure safe blood recruitment.Conclusion:It is necessary to strengthen blood testing efforts and continuously pay attention to the changing patterns of positive blood-borne diseases in order to improve blood quality and safety.
