Immunization Status

Immunization status or previous exposure to diseases is often assessed using serology. This testing can evaluate protection from diseases such as Bordetella pertussis, hepatitis A virus (HAV), hepatitis B virus (HBV), measles, mumps, rubella, varicella zoster virus, and polio. Serologic investigation is especially useful for individuals with missing or incomplete vaccination records. Immunization status may be needed for various reasons, including employment, school admission, or acceptance into an assisted living residence. Although laboratory test results can provide evidence of vaccination or exposure, there is no laboratory test available to definitively establish immunity.
