In order to find out the distribution of Genotype of those people infected with HBV (hepatitis B virus) from north Guangxi and the relationship between different immune status of HBV infected people and their genotypes, the HBV infected people are classified into three types according to immune tolerance, immune clearance ( response) and immune incompetence (residues). 150 cases from each type, a total of 450 cases are chosen to be tested with real time fluorescence quantitative PCR assay for detection of HBV infection in three kinds of different immune state of the HBV genotype.
