Hepatitis B is a member of Hepadnaviridar family of viruses transmitted primarily by body fluids especially serum, sexual transmission and transmission from mother to baby. The presence of HBV DNA in serum is a reliable marker of active HBV replication. HBV DNA levels are detectable by 30 days following infection, generally reach a peask at the time of acute hepatitis, and gradually decrease and disappear when the infection resolves spontaneously. In case of acute viral hepatitis with equivocal HBsAg test results, testing for HBV DNA in serum may be a useful adjunct in the diagnosis of acute HBV infection, since HBV DNA can be detected approximately 21 days before HBsAg typically appears in the serum.
