  • Title: Toward routine diagnosis of hepatitis B virus desoxyribonucleic acid.
    Author: Hess G, Reuschling M.
    Journal: Clin Biochem; 1993 Aug; 26(4):289-93. PubMed ID: 8242890.
    Abstract:
    Although a multitude of hepatitis B markers are available to discriminate different states of hepatitis B virus (HBV) infection, there remains a need to detect the HBV DNA itself. The HBV DNA test is the only test that can quantify the number of complete virions. As shown in this review, the diagnostic value of testing for HBV DNA depends on quantification, and there are situations in which in vitro amplification is necessary and others in which testing for HBV DNA without preamplification is best. Indications for analysis of HBV DNA include the early recognition of chronic hepatitis B, discrimination of different HBsAg carrier states, recognition of the evolution of variants, indication and follow-up of anti-viral therapy with interferon, and assessment of blood products for infectivity. In each of these cases quantification of HBV DNA improves the diagnosis of HBV infection and will become an important tool in the routine diagnosis of hepatitis B virus infection in the future.
