|Chemiluminescent Microparticle Immunoassay (CMIA)

The assay does not differentiate Hepatitis B surface antibody from vaccination or natural infection.
To assess immune status to HBV due to past infection or vaccination. Negative values: No evidence of antibodies to Hepatitis B surface antigen. Equivocal values: Indeterminate result. In patients who were vaccinated 6-8 weeks prior to this draw or previously infected with HBV, repeat testing is suggested. Those who were vaccinated for Hepatitis B virus years ago, may fall into this category due to waning immunity over time. Clinical correlation is required. Positive values: These results are consistent with immunity to the hepatitis B virus due to previous exposure to Hepatitis B virus or Hepatitis B vaccination.
Test is not intended for use in screening blood, plasma, or tissue donors. Performance characteristics have not been established for immunocompromised patients. Performance has not been established for the use of cadaveric specimens. Criteria for Rejection: Heat-inactivated, pooled, grossly hemolyzed, obvious microbial contamination.
