Synonyms

  • LAB472

Reference Interval

< 10 mIU/mL (Nonreactive)

Interpretive Data

Samples with a calculated value of 10 mIU/mL or greater are considered reactive (protective) in accordance with the recommendation of the CDC Immunization Practices Advisory Committee.   

Results should always be interpreted in conjunction with the patient’s medical history, clinical presentation, and other findings. Individuals who have received blood component therapies, for example, whole blood, plasma, immunoglobulin administered during the previous 3–6 months may have a false reactive anti-HBs result due to passive transfer of anti-HBs.  Assay performance characteristics have not been established in pregnant women, or in populations of immunocompromised or immunosuppressed patients.
