Texas Titer Testing

Some Texas 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.

Frequently Asked Questions

Does Texas require you to test?

There are currently no Texas antibody test regulations in place. While some institutions may accept a titer test in lieu of vaccination records for certain diseases, it is not mandated by state law.

Why are antibody tests (titer tests) important?

Showing proof of immunity via a titer test can prevent an individual from having to receive unnecessary vaccinations. Students who fall under Texas antibody test rules may want to take advantage of this option.

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 do titer tests test for?

A titer test is a blood test that is used to detect the presence of antibodies in the blood. The purpose of a titer test is to determine if a person has immunity against certain diseases. These results can be used to provide employers with proof of immunity, or to determine if a person needs to receive a certain vaccine.

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.

Texas Antibody Testing Regulations

With the exception of healthcare workers, the state of Texas does not require vaccinations for adults. There are also currently no statewide Texas titer test regulations in place. However, the Texas Department of State Health Services does advise residents to follow the CDC’s recommended vaccination schedule for adults aged 19 and over.

Texas law requires higher education students to be vaccinated against poliomyelitis, mumps, diphtheria, tetanus, rubella, and rubeola unless a legal exemption applies. In addition, the law requires healthcare students who have potential exposure to blood or other bodily fluids to have vaccinations against hepatitis B and varicella.

Texas titer test regulations allow students to submit lab results proving immunity to measles, rubella, mumps, hepatitis A, hepatitis B, or varicella in lieu of vaccination records.

In October of 2021, Texas Governor Greg Abbott issued an executive order banning any entity in the state, including private employers, from requiring COVID-19 vaccines for customers or employees. There are also no Texas antibody test regulations regarding COVID-19. The U.S. Equal Employment Opportunity Commission (EEOC) had previously issued a statement that it is a violation of the Americans with Disabilities Act (ADA) to require employees to submit a COVID-19 antibody test.

Texas Antibody Industry Regulations

Texas Admin Code §1.702 requires all health care facilities in the state to protect their patients from vaccine-preventable diseases by developing, implementing and enforcing policies and procedures that create vaccination requirements for all employees, based on their level of exposure. These policies and procedures must provide for both medical and “reasons of conscience,” including religious beliefs.

In addition, all publicly owned or financed institutions providing healthcare must offer the hepatitis B vaccine series to employees with occupational exposure. This is true even if health care is not the institution’s primary purpose.
