Disease Information


This assay measures total antibody (IgM + IgG) responses to Hepatitis A virus (HAV) infection. HAV total antibody is an indicator of recent or past infection with Hepatitis A virus or seroconversion following immunization. If recent HAV infection is suspected, also order Hepatitis A IgM antibody. Testing of serum for total anti-HAV is used to determine the immune status of an individual, to assess a person's risk for traveling to an endemic region or working in a high-risk area, and to assist in making decisions to administer HAV vaccine or immune globulin prophylaxis following exposure to HAV.


The presence of HAV total antibody is indicative of either a past or present infection with hepatitis A virus or vaccination against HAV. A positive
