Webation in the expression of the HBV surface antigen (HBsAg) and low copy number of HBV underlie the frequent false negative results obtained by qPCR. Worst of all, the lack of precision in qPCR assays has pre-vented the detection of very small differences in copy number between samples,7) especially when the initial copy numbers are already low. WebHepatitis B virus surface antigen (HBsAg) levels reflect disease status and can predict the clinical response to antiviral treatment; however, the emergence of HBsAg mutant …
