Chemiluminescent Immunoassay (CLIA)
This assay detects the presence of Hepatitis A specific antibodies (IgG + IgM). A non-reactive result indicates a lack of immunity to Hepatitis A infection. A reactive result indicates either vaccination, past infection, or current infection. To screen for current infection, the Hepatitis A Antibody, IgM assay should be ordered (order code HAMAB).
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
The performance of this assay has not been established with cord blood, neonatal specimens, cadaver specimens, heat-inactivated samples or body fluids other than serum.
