Some New York 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 New York Regulations

New York Antibody Industry Regulations

New York antibody test regulations and vaccination laws require employees and customers of many indoor businesses to obtain a COVID-19 vaccine.

There are additional New York antibody test regulations and vaccine requirements for healthcare workers. For example, hospital employers must offer the Hepatitis B vaccine to any employees that are exposed in the workplace. Hospitals must also require employees to prove immunity to measles and rubella. According to the CDC, healthcare workers include physicians, nurses, students, dental professionals, emergency medical personnel, laboratory techs, pharmacists, volunteers, and administrative staff.

Relevant New York Laws, Acts, and Legislation

Employees working at businesses that offer indoor activities must be vaccinated for COVID-19. These indoor businesses include indoor dining, entertainment, fitness, and certain meeting spaces. Customers must also show proof of vaccination to enter these facilities.
Employers must offer the Hepatitis B vaccine to all employees at risk for occupational exposure to bloodborne pathogens, as set forth in 29 CFR § 1910.1030. However, employees hold the right to decline the vaccination.
N.Y. Comp. Codes R. & Regs. ti. 10, § 405.3 – New York titer test regulations require hospital employees to show proof of a previous rubella infection or proof of vaccination, as well as a certificate of immunity against measles.

Frequently Asked Questions

Does New York require you to titer test?

New York antibody test regulations and vaccine laws generally do not require vaccinations or titer tests, with the exception of the COVID-19 vaccine. All New York residents ages 12 and older must show proof of the COVID-19 vaccine to enter many indoor businesses such as gyms, bars, theaters, museums, galleries, nightclubs, and restaurants.

New York antibody test regulations and vaccination laws also set specific requirements for healthcare workers. Hospital employees are required to show proof of previous rubella and measles infections or proof of vaccinations. Previous infections are determined with titer (antibody) testing.

What is different from the federal regulations?

Federal regulations do not require specific vaccinations or titer testing but rather offer recommendations. The Centers for Disease Control and Prevention (CDC) recommend vaccines for healthcare workers and employees in high-risk industries. These include vaccines against measles, mumps, rubella, hepatitis B, tetanus, diphtheria, pertussis, influenza, meningitis, pneumococcal, and varicella.

The Occupational Safety and Health Administration (OSHA) recommends that workers in healthcare and high-risk industries be vaccinated against COVID-19.

What do titer tests test for?

Titer tests analyze the blood for the presence of antibodies to certain communicable diseases. A positive test determines immunity to that disease. These diseases include measles, mumps, rubella, hepatitis A, B, and C, meningitis, influenza, COVID-19, tetanus, diphtheria, and pertussis.

Why are antibody tests (titer tests) important?

In New York, antibody tests can be used to determine immunity to certain diseases, in the event that an employer requires employee vaccinations. The immunity of workers prevents the spread of contagious diseases. Titer testing ensures safety in the workplace.

What does a positive titer test mean?

A positive titer test means that an individual has antibodies in the blood for a particular disease and that this person has developed immunity. A negative test means that the individual has no immunity and vaccinations should be considered.

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.
