Abstract: Objective To evaluate the consistency of results among three hepatitis B virus (HBV) nucleic acid-amplification testing (NAT) for blood donor screening and identify the influencing factors. Methods A total of 241 527 voluntary blood donation specimens negative for HBV by enzyme-linked immunosorbent assay (ELISA) were subjected to NAT. One hundred and twenty-five NAT-reactive specimens were selected for retesting using the three NAT systems, and hepatitis B core antibody (anti-HBc) detection was performed. The reactive detection rate of each system, cross-reactive detection rate across multiple systems, Cohen's Kappa coefficient analysis, and anti-HBc results were analyzed to evaluate differences in HBV detection. Results The reactive detection rates of systems A, B, and C were 96.78%, 48.24%, and 44.44% respectively. The Kappa coefficients ranged from 0.58 to 0.65, indicating moderate to substantial consistency. Among specimens reactive to system A, the reactive detection rate in system B was higher than that in system C. The positive rate of anti-HBc detection was 73.6% (92/125). Among transient NAT-reactive specimens, the positive rate of anti-HBc was 58%. Conclusion NAT can effectively reduce the risk of HBV transmission via blood transfusion, but no single NAT can completely eliminate this infection risk. Particularly in the screening of transient NAT-reactive specimens, combining multi-system NAT with anti-HBc testing can further reduce the risk of transfusion-transmitted HBV infection.
