86706 - Hepatitis B surface antibody (HBsAB)
Additional Information
The presence of anti-HBs indicates exposure to the Hepatitis B virus either through contact with infected blood or body fluids or by immunization.
Testing for the anti-HBs can be useful for:
1) Evaluating the recovery and prognosis of patients infected with Hepatitis B Virus (HBV)
2) Screening vaccine recipients
3) Evaluating epidemiologic factors associated with transmission of HBV.
Current literature suggests that a level of 10 mIU/mL or greater indicates protective immunity to HBV.
Note: AHBS is a test to assess the patient’s immune status toward the Hepatitis B Virus. If the question is, “has the patient ever been exposed to Hepatitis B”, then the Hepatitis B Core Total Antibodies (HBC) is the test of choice.
