Clinical significance

HDV (or hepatitis delta virus) is a defective RNA virus which depends on certain functions of the hepatitis B virus for its replication. Therefore, HDV infection is only possible in subjects simultaneously or previously infected with HBV. The HDV antigen is usually detectable over a period of one week to one month during the acute phase. HDV-specific IgM antibodies can be detected 2 to 5 weeks after the beginning of the infection and sometimes this is the only evidence. In chronic infection, these IgM antibodies sometimes persist. A positive total anti-HDV antibody test result is evidence of previous exposure to the virus. Now, a PCR-based assay for HDV RNA is available to measure viral activity.
