Enzyme Immunoassay (EIA) - Use:
Diagnose hepatitis D infection in patient with documented acute or chronic hepatitis B and at risk for HDV infection - Clinical Significance:
HDV infection occurs only in association with HBV infection. Acute HDV infection reflects either HDV acquisition at the time of acute HBV infection (coinfection), or recent exposure to HDV in a patient with chronic HBV infection (superinfection). HDV antigen is detected transiently during the early phase of acute HDV infection, but typically disappears as HDV-specific antibodies arise.
