Clinical Information: Hepatitis A Hepatitis A virus (HAV) is endemic throughout the world,
occurring most commonly, however, in areas of poor hygiene and low socioeconomic conditions. The
virus, which is transmitted primarily by the fecal-oral route, is spread by close person-to-person contact
and by food- and water-borne epidemics. Outbreaks frequently occur in overcrowded situations and in
high-density institutions and centers, such as prisons and health-care or day-care centers. Viral spread by
parenteral contact (with blood or oropharyngeal secretions) is possible but rare, because infected
individuals are viremic for a short period of time (usually 50%) to chronic
disease. In the United States, HCV infection is quite common, with an estimated 3.5 to 4 million chronic
HCV carriers. Cirrhosis and hepatocellular carcinoma are sequelae of chronic HCV.
Useful For: Screening to determine a patient's previous exposure to hepatitis Determining immunity to
hepatitis A and B Determining if a patient has been infected following exposure to an unknown type of
hepatitis
Interpretation: Hepatitis A virus (HAV) infection Anti-HAV is usually detectable by the onset of
symptoms (15-45 days after exposure). Serological diagnosis of acute HAV infection depends on the
detection of IgM antibody and its presence indicates recent exposure and potential infectivity. Hepatitis B
virus (HBV) infection Hepatitis B surface antigen (HBsAg) is the first serological marker present
following HBV infection. A positive result is diagnostic of acute or chronic HBV infection and is
