Order to confirm acute HDV infection is acute rather than chronic. May want to order hepatitis B core antibody, IgM to determine whether HDV co-infection or super-infection. HDV infection occurs only in association with HBV infection. Acute HDV infection reflects either HDV acquisition at the time of acute HBV infection (co-infection), or recent exposure to HDV in a patient with chronic HBV infections (super-infection). HDV antigen is detected transiently during the early phase of acute HDV infection, but typically disappears as HDV-specific antibodies arise.
