Hepatitis A Antibody, Total (IgM - IgG)

Hepatitis A Total (IgM - IgG) Blood Test is used to help diagnose a liver infection due to the hepatitis A virus. There are several causes of hepatitis and the accompanying symptoms, so this test may be used to determine if the symptoms are due to hepatitis A.

The total Hepatitis A antibody test detects both IgM and IgG antibodies and thus may be used to identify both current and past infections. This test will also be positive after receiving the vaccine, so sometimes it may be used to determine whether a person has developed immunity after vaccination.

  • A positive result Hepatitis A Antibody, Total that is not accompanied with Hepatitis A IgM test indicates  exposure to hepatitis A vairus but does not rule out acute infection. 
  • A Negative result Hepatitis A Antibody, Total that is not accompanied with Hepatitis A IgM test indicates no current or previous HAV infection; vaccine may be recommended if at risk.

Results of this hepatitis testing may indicate the following.

A total antibody test detects both IgM and IgG antibodies but does not distinguish between them.

If the total antibody test or hepatitis A IgG result is positive and someone has never been vaccinated against HAV, then the person has had past exposure to the virus. About 30% of adults over age 40 have antibodies to hepatitis A.
