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


Reference Range
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 or either current or past Hepatitis B infection. HBV vaccination leads to development of HBsAb but not to HBeAb.
