Test Overview

Test Methodology

Chemiluminescent Immunoassay (CLIA)

Test Usage

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 Range


* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
