Comparison of currently available assays for detection of hepatitis B virus DNA in the routine diagnostic laboratory.
Infection with the hepatitis B virus (HBV) continues to present diagnostic and therapeutic challenges worldwide. Today, many routine diagnostic laboratories have implemented assays based on molecular techniques for the detection of HBV DNA. However, the standard algorithm for specific diagnosis of HBV infection still relies on serologic testing. Molecular assays are employed for pretreatment evaluation, clinical staging and monitoring of antiviral therapy. Furthermore, molecular methods are essential for identification of mutations in the HBV genome. Although a continuous improvement of assay performance has been observed during recent years, lack of comparability of different molecular assays remains a problem to be resolved in the future. The limited range of linearity when employing conventional PCR will be overcome by using real-time assays.
