Abstract

The aim of this study was to investigate the diagnostic value of the serum markers HBsAg and HBeAg and PreS1 protein (PreS1-Ag) in quantifying the levels of hepatitis B virus (HBV) DNA in patients with chronic hepatitis B (CHB). One thousand CHB patients were recruited from Beijing You’an Hospital between June and December 2012. Serum HBsAg and HBeAg levels were detected by electrochemiluminescence immunoassay. Enzyme-linked immunosorbent assay and fluorescence quantitative PCR were used to determine the level of PreS1-Ag and HBV DNA, respectively. We observed a low correlation between HBsAg and HBV DNA (r = 0.172, P 10 > 7 (r = 0.597, P
