Result analysis of serology test and NAT quantitative detection of HBV DNA reactive blood donors
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 11
Abstract
Objective To investigate the related viral markers of HBV DNA reactive samples among voluntary blood donors in Shiyan area, so as to provide some reference for donor re-entry. Methods From August 2019 to June 2021, 78 samples with HBV DNA reactivity from voluntary blood donors in our blood station were collected, and they were further detected for HBV viral markers(using chemiluminescence assays), nucleic acid testing(NAT) of virus quantification and sequencing analysis. Results Forty-seven (60.3%)out of 78 HBV DNA reactive samples were from repeated blood donors, and 56.4%(44/78)of them were over 45 years old. Among the five viral markers of hepatitis B, 37.2%(29/78) were positive for anti-HBs alone, 19.2%(15/78) were positive for anti-HBe+ anti-HBc and anti-HBs+ anti-HBe+ anti-HBc, and 11.5% (9/78) were all items negative.A total of 62.8%(49/78) of samples were detected by NAT quantification and seven samples had been successfully sequenced for HBV. Conclusion NAT can effectively minimize the missed detection of HBsAg methodology and reduce the risk of HBV transmission through blood. The re-entry of HBV DNA reactive blood donors should be treated with care.
