- Four subtypes of hepatitis B surface antigen are useful in the epidemiologic studies of the route of virus transmission and clinical significance of simultaneous occurance of hepatitis B surface antigen and antibody to hepatitis B surface antigen in the same serum as well as useful marker for population migration. The sera were obtained from 214 HBs Ag positive patients who are diagnosed as chronic liver disease and following up in the Yeungnam university hospital. The subtypes were determined by solid-phase sandwich EM using monoclonal antibodies. Among 214 specimens, the subtype adr was 93.9%, adw was 2.8%, ayr was 0.9%, ar was 0.9%, adwr was 1.4% and ayw was not detected. There were no correlation between subtype pattern and disease. In summary, the subtype adr was prominent in our study and the difference of subtype pattern by severity of disease was not significant. However, to determine the prognostic value of HBs Ag subtype and relationship between subtype and disease progression, long-term follow up will be needed.
