Hepatitis B virus (HBV) is a well-kown agent of acute and chronic 
hepatitis, with approximately 300 million chronic carriers around the 
world. In the early 1970s, serotyping of HBV was introduced as a means 
of classification of varying HBV strains. Serotyping refers to the 
seroreactivity to three antigenic determinants residing in the HBV S 
antigen. The genomic basis for the seroreactivity has been elucidated 
by sequence analysis of the S gene, and it has been shown that the 
serotypes do not truly reflect phylogenetic relatedness within HBV. 
Genotyping methods based on sequence analysis of the HBV genome have 
recently been developed. This test can determine the following HBV 
genotypes: A1-A3, B1-B3, C1, C2, D1-D6, E, F1 and F2.
