The hepatitis A test looks for antibodies to the HAV virus in the blood. These antibodies are proteins made by the body in response to the presence of the hepatitis A virus. Hepatitis A is a liver infection which is typically spread through exposure to contaminated fecal matter.
This test can be used to look for both recent and past exposure to Hepatitis A. It can also be used to verify immunity to Hep A.
A negative result indicates the absence of HAV-specific IgG antibody, implying no past exposure or immunity to HAV infection.
A positive result indicates the presence of HAV-specific IgG antibody from either vaccination or past exposure to hepatitis A virus.
