- aHBV DNA was detected by the NAT from 475,538 blood donors with negative HBsAg and normal ALT level (<50U/L). HBV DNA+/HBsAg- carriers were detected 1–3 times for HBV DNA and sero-markers by the follow-up. The blood samples were detected for HBV DNA+/HBsAg- in follow-up samples were defined as OBIs, for seroconversion of HBsAg were defined as window period infections (WPIs), while no available of follow-up testing were defined as unclassified that might include false positive of HBV DNA samples
