Methodology

Immunoassay (IA)

Limitations

Results obtained from immunosuppressed patients should be interpreted with caution. Patients receiving mouse antibody therapy may produce false-negative results. False-positives may be detected shortly after immunication to influenza and with patients with hypergammalobulinemia, positive rheumatoid factor, and connective tissue disorders.

Reference Range(s)

Non-Reactive

Clinical Significance

This assay does not distinguish between Total B Core Antibody IgG and IgM detected before or at the onset of symptoms; however, such reactivity can persist for years after illness, and may even outlast anti-HBS. Occasionally Hepatitis B Core Antibody may be the only marker of either current or past Hepatitis B infection. HBV vaccination leads to development of HBsAb but not to HBeAb

Reference ranges are provided as general guidance only. To interpret test results use the reference range in the laboratory report.
