: HBV is one of the leading causes of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. More than 2 billion people are infected worldwide and it is responsible for 1 million deaths annually. In developed countries, HBV is a blood-borne viral infection transmitted via sexual activity, injection-drug use or occupational exposure. Almost all vertical transmission (mother to infant) of HBV has been eliminated in the United States due to the institution of an aggressive HBV vaccination program and the immunoprophylactic treatment of infants born to HBsAg positive mothers. Chronic HBV patients may go on to develop more severe conditions such as cirrhosis, hepatocellular carcinoma, liver failure and other complications. There have been recent advances in antiviral therapy with the development of new nucleoside analogues. This has supported the need for HBV viral quantification for the monitoring of treatment.
: Serum or plasma should be separated from red cells and refrigerated within 6 hours of collection.
