Frequently Asked Questions

Does Kentucky require you to titer test?

While there is no legislation that specifically mandates Kentucky titer testing, certain industries may still require employees to meet specific immunization requirements. If permitted, titer testing can be used as proof of immunity to avoid unnecessary vaccinations.

What does a positive test mean in Kentucky?

If a Kentucky titer test reads positive, this indicates that a certain amount of antibodies surpassing a set value have been detected within a blood sample and signals immunity against a certain infectious pathogen such as measles.

How often do you have to get tested?

While the state of Kentucky holds no routine titer testing requirement, employees who are at risk of infections, such as health care workers, may want to consider an annual titer test to understand their levels of ongoing immunity against various infections.

Why are antibody tests important?

Antibody testing can determine if a person has immunity against certain diseases. This process may be necessary for those who are unsure of their vaccination status, or for employers that require proof of immunity to diseases. Testing for antibodies in the blood is also commonly performed to avoid unnecessary vaccinations for someone who has already developed immunity.

How much do antibody tests (titer tests) cost?

This depends on which type of antibody test is ordered. Health Street offers a variety of individual antibody testing services as well as package deals. For a comprehensive list of antibody tests and pricing, take a look at our antibody test registration page.

How long are titer tests good for?

Titer test results are records of whether a person has tested positive or negative for immunity against certain diseases. Depending on the type of disease, some employers may require employees to periodically test for antibodies, and may require employees to receive certain vaccinations before they are permitted to work. The frequency of testing depends on many factors, including the industry and the type of disease or vaccine.

Kentucky Antibody Testing Regulations

According to current state rules and Kentucky titer test regulations, there are no laws that require residents to undergo antibody tests for any particular reason. While there are no statewide laws regarding Kentucky antibody testing, it’s important to note that there are occasional instances where a specific job industry may require proof of immunization or Kentucky titer test.

Immunization or Kentucky antibody test regulations are typically experienced in industries such as healthcare, where employees commonly work around high-risk individuals. If you encounter any sort of workplace immunization requirement, be sure to first discuss with an employer if a Kentucky titer test can be used as proof of immunity to avoid any unneeded vaccinations.

Similarly, with ongoing changes to countrywide COVID-19 regulations, be sure to refer to workplace policy regarding immunization and/or Kentucky antibody testing requirements.

Kentucky Antibody Industry Regulations

While there are no Kentucky antibody testing regulations that require the general population to undergo antibody testing, it’s important for employers and employees to remain mindful of various industry immunization requirements. For instance, certain Kentucky healthcare professionals are required to provide proof of immunity against certain infectious diseases.

Under Kentucky regulation 209.552, every long-term health care facility must require employees and long-term residents to be immunized against pneumococcal and influenza viruses. Under such law, the long-term health care facility is also required to provide or arrange immunization of these infectious diseases upon employment or facility admission.

While not employee-related, it’s important to also note that many Kentucky education sectors require students to provide proof of immunization against a variety of infectious pathogens including measles, rubella, and hepatitis B. In certain cases, Kentucky titer testing can be used to demonstrate immunity rather than undergoing repeated vaccination.
