The HAV Total Antibody test detects the presence of antibodies (both IgM and IgG) against the Hepatitis A virus (HAV) in the blood. Hepatitis A is a highly contagious liver infection caused by the Hepatitis A virus, typically spread through contaminated food, water, or close contact with an infected person.
This test is used to determine whether a person has a current or past Hepatitis A infection, or has developed immunity either through vaccination or prior infection. The total antibody test detects both IgM antibodies (indicating recent or active infection) and IgG antibodies (indicating past infection or immunity). It is used to screen individuals with symptoms of hepatitis, evaluate exposure to the virus, and confirm immunity status before or after vaccination.
