Hepatitis B Surface Antibody, Quantitative, HBIG Assessment
Also known as: Anti-HBs, Antibody to Hepatitis B Surface Antigen, HBV
Use
This test is designed for use in assessing therapy with HBIG for patients who have had a liver transplant.
Special Instructions
Not provided.
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 have false-positive results for antibody to hepatitis B surface antigen.
Methodology
Immunochemiluminometric assay (ICMA). Samples will be diluted and titered to endpoint.
