Overview of Louisiana Regulations

Louisiana Antibody Testing Regulations

In the state of Louisiana, a positive titer test indicates that antibodies have been produced by a previous vaccination or prior immune system response and were detected in an individual’s blood sample. In other words, a positive result signals immunity against a variety of infectious pathogens, including mumps and measles. Under current state law, there are no Louisiana antibody testing regulations that mandate titer testing of the general public for any particular reason.

However, it is important to note that in certain situations, such as employment, Louisiana residents may be required to show proof of immunization against certain infectious diseases. For instance, employers may require immunization against chickenpox, hepatitis B, and now more recently, COVID-19. If you face such requirements, it’s important to discuss with your employer to learn if Kansas antibody testing can be used as proof of immunity to fulfill any requirements.

Louisiana Antibody Industry Regulations

While there are no government-level Louisiana titer testing regulations for the general public, requirements may differ per industry or employer. According to the Centers for Disease Control and Prevention (CDC), the state of Louisiana currently does not require healthcare workers to meet any sort of immunization requirements. However, as the COVID-19 landscape continues to evolve, it’s important to remain up to date and discuss any immunization or Louisiana titer testing requirements with employers.

Although not employment-related, it’s also important to also note that many Louisiana higher education institutes will require proof of immunization against a variety of infections to enroll. In cases of immunizations such as hepatitis B, a Louisiana antibody test may be used to demonstrate immunity and avoid any required vaccinations.

Relevant Louisiana Laws, Acts, and Legislation

Louisiana Revised Statutes 17:170: This collection of Louisiana laws outlines that various immunization requirements higher education students (Louisiana universities and colleges) must meet to fulfill the criteria for enrollment. Such immunizations include but are not limited to measles, meningococcal, and rubella.
CDC Louisiana Immunization Laws for Healthcare Workers: While healthcare workers are not required to meet any sort of immunization requirement, this guide by the CDC further outlines some vaccination offering requirements for patients and residents of hospitals and correctional facilities.

Frequently Asked Questions

Does Louisiana require you to titer test?

Under current legislation, no law requires Louisiana antibody testing on residents for any specific reason. However, you should always discuss any immunization requirements with your employer to see if titer testing can be used to prove immunity.

What does a positive test mean in Louisiana?

When Louisiana titer test results come back positive, this means that antibodies have been detected in your blood sample which signals possible immunity against infectious pathogens including measles, mumps, and rubella.

How often do you have to get tested?

While Louisiana holds no routine titer testing laws or requirements, employees who are at risk of infections, including health care workers, should consider annual titer testing to understand their ongoing levels of 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. For more information about specific diseases and the recommended vaccine schedule, try taking a look at our Vaccines & Immunizations page.
