Status and characteristics of blood donor deferrals: a retrospective analysis in Tianjin from 2016 to 2020 / 中国输血杂志

ABSTRACT

【Objective】 To analyze the profile, preliminary screening and laboratory test results of voluntary blood donors in the past five years, so as to provide basis for formulating the recruitment strategy, ensuring clinical blood use and improving blood safety and quality. 【Methods】 789 570 voluntary blood donors from 2016 to 2020 were classified according to the category, and the positive rate of blood testing results was statistically analyzed. 【Results】 The proportion of transfusion-transmitted infections (TTI), including HBsAg, anti-HCV, anti-T, and anti-HIV, was led by HBsAg, except for anti-TP leading in 2018. The positive rate of ELISA items and ALT tests showed statistical significance by age groups(P0.05). The positive rate of preliminary screening and laboratory testing showed differences among occupation and educational background(P0.05). The number of HIV positive males (n=228) was higher than that of females(n=3), and the proportion of workers (23.08%~40.74%) and staff (16.67%~46.67%) were large. In 2020, however, the proportion of HIV infected students increased sharply to 21.62%. Sole HBV DNA positive cases was the most (n=460), while the number of sole HIV RNA(n=3) and HCV RNA positive cases (n=6) were rather low. 【Conclusion】 Targeted recruitment strategies should be formulated according to the profile and test results of voluntary blood donors to further improve blood test ability and ensure blood safety.
