Reporting

Reference Range:

Negative

< 9.9 mIU/mL

 

Interpretation:

  • Index < 10.0 mIU/mL are considered NEGATIVE for Anti-HBs.  Individual is considered to be not immue to infection with HBV
  • Index ≥ 11.0 mIU/mLare considered POSITIVE for Anti-HBs.  Individual is considered to be immune to infection with HBV
  • Index ≥ 9.0 - < 11.0 mIU/mL are considered EQUIVOCAL and must be repeated in duplicate.  Samples which are Equivocal on 2 of the 3 replicates < 10 mIU/mL should be reported as NEGATIVE and 2 of the 3 replicates ≥ 10 mIU/mL should be reported as POSITIVE.

 

Critical Decision:

None

Clinical Significance

Detection of anti-HBs is critical in establishing whether complete resolution of the infection has occurred as well as in establishing the acquisition of immunity, whether acquired as a result of natural HBV infection or vaccination.

 

Different serologic markers or combinations of markers are used to identify different phases of HBV infection. They determine whether a patient has acute or chronic HBV infection, is immune to HBV as a result of prior infection or vaccination, or is susceptible to infection. Markers include:  HBsAg, Anti-HBs, Anti-HBc Total (IgM & IgM) and Anti-HBc IgM.  It is recommened that Hepatitis B Screening be performed in a triple panel; HBsAg, Anti-HBs, and Anti-HBc Total.
