Test Overview
Chemiluminescent Immunoassay
Presence of hepatitis antibody indicates previous hepatitis B infection or vaccination. 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.
Non-Reactive: <10 mIU/mL (no immunization); Reactive: >=10 mIU/mL (immunization or previous hepatitis B infection).
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Specimen Requirements
Collect specimen in an SST or red top tube. Centrifuge, aliquot serum into a plastic vial and refrigerate up to 3 days or freeze for longer storage. Specimens in primary collection tubes are stable 8 hours at room temperature and 1 day refrigerated prior to analysis. Post-vaccination samples should be collected 4-6 weeks from the date of vaccination.
