Specimens submitted for detection of antibody to HBV surface antigen (Anti-HBs) are tested using a chemiluminescent microparticle immunoassay (CMIA) that detects IgG anti-HBs.  This automated assay on the Abbott Architect system provides a quantitative determination of Anti-HBs.  The test is indicated for assessing the response to HBV vaccination, determination of HBV immune status and for the diagnosis of HBV infection when used in conjuction with clinical and other laboratory data.  Results are reported as follows:

<8.00mIU/ml                             Nonreactive

>8.00 to <12.00 IU/ml               Equivocal

>12.00 IU/ml                             Reactive

For immune status determination, nonreactive and equivocal results are considered non-immune.  This assay does not distinguish between infection and vaccination.
