Comments
This test is intended for use in the qualitative determination of IgM antibody to hepatitis A virus in human serum or plasma. This assay is indicated for use as an aid in clinical laboratory diagnosis of acute or recent hepatitis A virus infection, usually within 6 months; however it has not been established as an aid in determining susceptibility to HAV infections prior to or following vaccination in infants, children, or adolescents.
