Additional information Anti-HDV is a marker for acute or persisting infection with the "delta" agent, a defective RNA virus which can only infect HBV-infected patients. Combined HBV-HDV infection may be more severe than HBV infection alone. Antibody to HDV ordinarily persists for about 6 months following acute infection; detection beyond that point is evidence that the patient has become a carrier. Clinical use is to diagnose hepatitis delta virus (HDV) infection in patients with fulminant hepatic failure, or known previous HBV infection. A positive HDV antibody test, along with the presence of HbsAg, indicates HBV/HDV coinfection
