Serum hepatitis is still recognized as a major public health problem in many countries. The most common etiologies are acute viral hepatitis A and B, and hepatitis B virus (HBV) was known as the pathogen of serum hepatitis. since the HBV causes chronic hepatitis. HBV infection is hyperendemic in Korea. It is known that 8% and 1% of the Korean population is chronic carriers of HBV. The total number of 487 serum specimen (old people’s home 190, causal ward-Daegu hope village 297) were collected at the laboratory of Department of Clinical Pathology of Daegu medical center. The laboratory tested the specimen to detect for hepatitis B surface antigen (HBsAg) and anti-HBs using reverse passive hemagglutination (RPHA) and passive hemagglutination (PHA) method between April, 2011 and June, 2011. In one-step test, HBsAg and anti-HBs of Humasis were used. The positive rate for HBsAg was 6.80% (33/487), and the rate in male was 6.93% (19/274) higher than that of female 6.57% (14/213). In the positive rate of HBsAg by age group, the highest positive rate group was in the group of 40-49 years in male (12.0%), and 50-59 years in female (17.65 %). The overall positive rate for anti-HBs was 42.70% (208/487), showing the higher positive rate of 43.80% in male (120/274) than that of 41.30% (88/213) in female. The highest positive rate of anti-HBs in age group was the 40-49 years group in male (52.00%) and the group of under 29 in female (66.67%).
