Viral Hepatitis Screening and Diagnosis Algorithm

Laboratory testing for viral hepatitis is appropriate for screening (eg, prenatal screening for hepatitis B virus [HBV] and hepatitis C virus [HCV]) or testing at new onset of symptoms such as jaundice, anorexia, or dark urine, or after a known or suspected exposure to hepatitis virus. In most cases, initial testing should include serology for hepatitis A, B, and C antibodies. Interpretation of results and determination of further testing should be based on clinical situation and patient history.
