Levels of hepatitis B virus (HBV) replication during the nonreplicative phase: HBV quantification by real-time PCR in Korea.

The levels of HBV replication in the nonreplicative phase are not clear. We conducted this study to evaluate the levels of viral replication during the nonreplicative phase in chronic HBV-infected Korean patients using real-time PCR. A total of 125 patients were classified into three groups: inactive HBsAg carriers, inactive liver cirrhosis patients, and resolved chronic HBV-infected patients with loss of HBsAg.
