Text: Quantitates Hepatitis B Virus DNA down to 0.01 pg/mL for establishment ofa baseline and to monitor viral load. The most important test for determining the efficacy of antiviral treatment is quantitative HBV DNA monitoring. HBV DNA testing is useful in detecting potential disease transmission from prospective donors and for post-transplantation monitoring. Although HBeAg is considered an indirect monitor of viral replication, high viral replication may occur without circulating HBeAg, due to mutations of the virus preventing the production of HBeAg.
