Test Details

Use

This test is useful for quantitative (i.e., titer) evaluation of possible immunity in individuals who are at increased risk for exposure to hepatitis B (i.e., hemodialysis unit personnel, venipuncturists, etc.). This test can be used to evaluate the need for hepatitis B immune globulin after needlestick injury, to evaluate the need for hepatitis B vaccine and to follow immune status after hepatitis B vaccination.

Limitations

Presence of anti-HBs is not an absolute indicator of resolved hepatitis infection nor of protection from future infection. Since there are different serologic subtypes of hepatitis B virus, it is possible (and has been reported) for a patient to have antibody to one surface antigen type and to be acutely infected with a virus of a different subtype. Thus, a patient may have coexisting HBsAg and anti-HBs. Transfused individuals or hemophiliacs receiving plasma components may give false-positive tests for antibody to hepatitis B surface antigen.

Methodology

Immunochemiluminometric assay (ICMA)

Reference Interval

• Immunity: >10.0 mIU/mL
