Automated EIA assay (Roche Elecsys). HBeAg indicates ongoing HBV replication and liver disease while anti-HBe is usually associated with lower levels of viremia and remission of liver disease. Both markers play an important role in routine monitoring of progression of liver disease (HBeAg to anti-HBe seroconversion/reversion) and outcome of treatment.
