Hepatitis A Immunity Test - Hepatitis A Virus Total Antibody Test (HAV Total)

This test detects the presence of total antibodies against hepatitis A virus (HAV). It identifies both IgM antibodies (indicating an acute infection) and IgG antibodies (indicating a previous infection or vaccination and lifelong immunity). A positive result means the person has either had an acute infection (if IgM is present) or is immune due to a previous infection or vaccination (if IgG is predominant after IgM disappears).
