Methods We enrolled all patients tested for HBV serological markers, such as HBV surface antigen （HBsAg）, HBV surface antibody （HBsAb）, hepatitis B e antigen （HBeAg）, hepatitis B e antibody （HBeAb）, HBV core antibody （HBcAb）, and HBV-DNA from July 2008 to July 2009 in Peking Union Medical College Hospital. The positive rate of each HBV serological marker was calculated according to gender, age, and department, respectively. The positive rates of HBV-DNA among patients with positive HBsAg were also analyzed. Results Among 27 409 samples included, 2681 （9.8%） were HBsAg positive. When patients were divided into 9 age groups, the age-specific positive rate of HBsAg was 1.2%, 9.6%, 12.3%, 10.9%, 10.3%, 9.7%, 8.0%, 5.8%, and 4.3%, respectively. The positive rate of HBsAg in non-surgical department, surgical department, and health examination center was 16.2%, 5.8%, and 4.7%, respectively. The positive rate of HBsAg of males （13.3%） was higher than that of females （7.3%, P=0.000）. Among the 2681 HBsAg （＋） patients, 1230 （45.9%） had HBV-DNA test, of whom 564 （45.9%） were positive. Patients with HBsAg （＋）, HBeAg （＋）, and HBcAg （＋） result usually had high positive rate of HBV-DNA results （71.8%, P=0.000）. Conclusions Among this group of patients in our hospital, the positive rate of HBsAg was relatively high. Age group of 20-29, males, and patients in non-surgical departments were factors associated with high positive rate of HBsAg.展开更多
