Hepatitis A Immunity (IgG IgM)
The purpose of hepatitis A testing is to determine if a person has been infected by the hepatitis A virus (HAV).
Diagnose current infection: diagnose the cause of hepatitis in patients with signs and symptoms of this disease.
Assess immunity: After a person recovers from a hepatitis A infection, they become immune to future infections due to the development of protective antibodies. Hepatitis A testing may show that a person has developed protective antibodies to hepatitis A after recovering from a past infection or because they previously received a hepatitis A vaccination.
Biomarkers:
Hepatitis A immunoglobulin M (IgM anti-HAV) antibody: When a person is first infected with hepatitis A, the body produces IgM anti-HAV antibodies. These antibodies are usually detectable from two weeks after symptoms begin to around six months later.
Hepatitis A immunoglobulin G (IgG anti-HAV) antibody: The IgG anti-HAV antibody test detects IgG antibodies that develop later in the course of the disease. IgG antibodies are detectable in the body for life, providing protection against a future hepatitis A virus infection. The IgG anti-HAV test is used to detect past HAV infections and may occasionally be used to determine if an individual has developed immunity from a previous infection or vaccination.
