Wisconsin Titer Testing

Register Now

Some Wisconsin employers require antibody testing, also known as titer testing, as part of their pre-employment screening process. Existing employees may also be tested periodically as part of the process to ensure safety in the workplace, especially for industries such as healthcare or education. Titer testing is the first step to determining if someone is immune to certain diseases, such as varicella (Chickenpox), hepatitis A, hepatitis B, hepatitis C, measles, mumps, rubella, or COVID-19. If the antibody test indicates that an individual is not immune, Health Street can also provide services for vaccines and immunizations.

Overview of Wisconsin Regulations

Wisconsin Antibody Testing Regulations

When a Wisconsin antibody test comes back positive, it means that enough antibodies were produced by a previous infection or vaccination and have been detected in a blood sample to declare a person "immune" against a specific infectious pathogen, such as measles, mumps, and hepatitis B. There are no Wisconsin titer test regulations. Under current state law, Wisconsin antibody tests are not mandated for general residents.

However, certain industry employees should remain mindful of the immunization requirements they may face. Typically, those who face immunization requirements are those who work around a high-risk population, including those part of the healthcare industry. In some cases, Wisconsin antibody tests can be used to demonstrate immunity against diseases that would require vaccination, so be sure to consult with employers and workplace policies.

As the country continues to navigate the COVID-19 pandemic, it's important to also keep up with related local regulations and laws that may impact your current employment situation. As with general immunization requirements, be sure to understand current workplace policy to understand if Wisconsin titer testing can be used to demonstrate immunity.

Wisconsin Antibody Industry Regulations

While there are no state laws or Wisconsin antibody test regulations for residents, certain employees in the state still face immunization requirements in the workplace. Under Wisconsin Adm. Code § 124.07, hospitals are required to implement and maintain an employee health program that ensures immunization against rubella for certain employees.

Under this state code, hospital employees who have direct contact with rubella, pediatric, or childbearing female patients are required to maintain documentation of immunization against rubella. A Wisconsin hospital that faces this rubella immunization mandate includes but is not limited to institutions such as children's hospitals, psychiatric hospitals, and maternity facilities.

In addition to previous rubella vaccination records, proof of a positive Wisconsin titer test can be used to demonstrate immunity against rubella. While not immediately related to employment, it's important to also note that many university students, including medical students, are commonly required to comply with Wisconsin antibody test regulations or vaccination requirements for enrollment.

Wisconsin DOH Bloodborne Pathogens and Exposure Control: A summary supplied by the Wisconsin Department of Health Services which outlines bloodborne pathogen and exposure control protocol, including the OSHA issue regulation mandating that employees at risk of bloodborne pathogen exposure must provide a hepatitis B vaccination series and post-vaccination Wisconsin antibody testing in the event of exposure.

Frequently Asked Questions

What do titer tests test for?

Wisconsin titer tests are used to measure the number of antibodies against a variety of infectious pathogens, including hepatitis B, measles, and varicella-zoster (chickenpox), produced by the body from prior vaccination or infection.

Why are antibody tests (titer tests) important?

Wisconsin's antibody tests are a vital tool that provides insight into individual levels of immunity against various infectious diseases such as measles. Titer test results can also be used to determine if certain vaccinations are necessary.

What is an antibody titer score?

To produce an antibody titer score, a person's serum is diluted and then retested for antibodies. If antibodies can still be detected, then the serum is diluted and then tested again. This process is repeated until the person's serum has been diluted as much as possible, but the presence of antibodies can still be detected.

What does a positive titer test mean?

If titer test results show that a person is positive, this may indicate that the individual has previously been infected with the disease or vaccinated against it. The individual may be presumed to have immunity against that specific disease, and vaccination may not be required at this time.
