Analysis of blood donor pre-donation deferral in Zhengzhou

Abstract

Objective To identify low-risk donor population and optimize blood screening, recruitment and consultation strategies via retrospectively analyzing the unqualified results of Hb, ALT, HBsAg, TP before whole blood donation from 2015 to 2018. Methods Pre-donation examinations of Hb, ALT, HBsAg and TP were conducted by copper sulfate method, dry chemical method, and TPPA etc. Results A total of 70 146 out of 685 469 blood donors in Zhengzhou city from 2015 to 2018 were deferred due to unqualified pre-donation. The unqualified rates of Hb, ALT, HBsAg and TP were 1.75%(11 996/685 469), 7.78%(53 329/685 469), 0.60%(4 113/685 469) and 0.10%(685/685 469), respectively. For Hb deferral, 2.5%(17 137/685 469) were male and 97.5%(668 332/685 469)female; for ALT deferral, 85.9%(588 818/685 469) male and 14.1%(96 651/685 469) female. Conclusion The causes of pre-donation deferral in whole blood donors were mainly ALT, then Hb. Hb deferral showed an increasing trend and dominated by female donors, while ALT deferral was dominated by male donors. The overall unqualified rate of ALT, HBsAg and TP, however, are decreasing year by year through taking targeted measures, strengthening the publicity and education of blood donation, standardizing the blood collection and supply process.
