California Titer Testing
Many industries, such as healthcare or education, will require proof of vaccination or immunity against certain diseases. Some people may have no proof of their immunity, or they may be uncertain about their vaccination status. For people who need to provide proof of immunity to an employer in California, Health Street offers antibody testing that can identify if a person has previously been infected with a specific disease or virus. We offer a variety of antibody testing services that can test for different antibodies, such as varicella (Chickenpox), hepatitis A, hepatitis B, hepatitis C, measles, mumps, rubella, or COVID-19.

Overview of California Regulations
California Antibody Testing Regulations
While there are no general vaccination or California antibody test regulations for adults, the California Department of Public Health refers to the CDC’s recommended guidelines regarding immunization guidelines for adults aged 19 and over.
The state of California does not require vaccinations for college-aged children but has provided recommendations for California colleges and universities with campus housing to follow. Each school can set its own requirements, and many allow for a California titer test when vaccination records are not available.
California Antibody Industry Regulations
In the state of California, employees working in certain industries must show proof of immunity to specific diseases, either by providing vaccination records or California titer test results. Under current California laws, employers must offer healthcare workers and ambulatory care employees access to vaccinations. Under California law, all workers in California healthcare facilities are now also required to be fully vaccinated against COVID-19, including a booster when appropriate.
The U.S. Equal Employment Opportunity Commission has stated that in light of current CDC Interim Guidelines, the Americans with Disability Act (ADA) does not allow employers to require antibody testing before allowing employees to work. In light of this, there are no California antibody test regulations that allow for mandated COVID-19 antibody testing.

Frequently Asked Questions
What does a positive titer test mean?
If a titer test is “positive,” it means that the individual taking the test has immunity to the disease. In certain situations, California titer test regulations allow individuals to submit a positive titer test instead of a vaccination record.
Does California require you to test?
In some situations, California antibody test regulations allow titer testing if vaccination records are not available. However, if an individual can submit vaccination records, titer testing is not required.
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.
