Controversies exist regarding the classification of the different clinical phases of chronic hepatitis B (CHB) because hepatitis B virus (HBV) DNA and alanine aminotransferase levels fluctuate over time.1,2 To improve the distinction of clinical phases and the associated spectrum of clinical outcome,3,4 hepatitis B surface antigen (HBsAg) levels may be of help.5–7 We hypothesize that HBV genotype specific HBsAg levels are needed for the identification of different clinical HBV disease phases.7
