Results are mailed upon completion.

REPORTING & INTERPRETATION

Results are reported as REACTIVE, BORDERLINE, or NON-REACTIVE.

REACTIVE indicates the presence of antibody as a result of a previous Hepatitis B infection or vaccination series and the patient is considered immune.

BORDERLINE indicates borderline status and interpretation should be based on other clinical information or subsequent testing.

NONREACTIVE indicates non-detectable or absent levels of antibody.  If the patient is known to have vaccinated against Hepatitis B, their antibody levels may be present, but non-detectable.
