The development of sensitive assays to detect small amounts of hepatitis B virus（HBV） DNA has favored the identification of occult hepatitis B infection（OBI）, a virological condition characterized by a low level of HBV replication with detectable levels of HBV DNA in liver tissue but an absence of detectable surface antigen of HBV（HBs Ag） in serum. The gold standard to diagnose OBI is the detection of HBV DNA in the hepatocytes by highly sensitive and specific techniques, a diagnostic procedure ...
