Characteristics of NAT+ blood donors screened for transfusion-transmitted infectious markers in Hainan
Journal Title: Chinese Journal of Blood Transfusion - Year 2024, Vol 37, Issue 7
Abstract
Objective To explore the epidemiological characteristics of voluntary blood donors with enzyme-linked immuno-sorbent assay (ELISA) negative and nucleic acid testing (NAT) positive in Hainan from 2012 to 2022, so as to provide reference for developing rational blood screening strategies. Methods The screening results for transfusion-transmitted disease markers in 1 161 042 blood samples in Hainan from 2012 to 2022 were retrospectively analyzed. All samples have been measured twice by ELISA and once by NAT. Statistical methods were used to analyze the proportion of ELISA negative and NAT positive (ELISA-/NAT+ ) among voluntary blood donors and its relation with factors including gender, age, ethnicity and region. Results Among the voluntary blood donors in Hainan from 2012 to 2022, the overall proportion of ELISA-/NAT+ was 0.19% (2 151/1 161 042), and the difference was statistically significant (P<0.05). The ELISA-/NAT+ rate in hepatitis B virus (HBV) DNA, hepatitis C virus (HCV) RNA, human immunodeficiency virus (HIV) RNA and non-discriminating reactive (NDR) was 0.10%, 0.000 3%, 0.000 4% and 0.09% respectively. The ELISA-/NAT+ rate of voluntary blood donors varied among different age groups and gradually increased with age (P<0.05). The ELISA-/NAT+ rate of male donors (0.22%, 1 729/795 032) was significantly higher than that of female donors (0.12%, 422/366 010, P<0.05). The ELISA-/NAT+ rate of Han blood donors was significantly lower than that of Li and Miao blood donors (P<0.05). The ELISA-/NAT+ rate was the highest of 0.32% (301/94 046) in the eastern region, followed by 0.30% (341/113 783) in western region, and 0.16% in both southern and northern region, which also presented a significant difference (P<0.05). Conclusion The ELISA-/NAT+ rate of voluntary blood donors in Hainan fluctuated from 2012 to 2022, which was related to factors such as age, gender, ethnicity and region.
