Some New Mexico 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 Mexico Regulations

New Mexico Antibody Industry Regulations

New Mexico antibody test regulations and vaccination laws generally don't require titer testing and vaccinations, but there are some exceptions for workers in high-risk industries, such as healthcare.

Healthcare workers in New Mexico are not required to be vaccinated or prove immunity to hepatitis B, influenza, varicella, and pneumococcal. However, New Mexico antibody test regulations and vaccination laws require employers to ensure their employees have immunity against rubella.

In addition, New Mexico requires workers in high-risk industries to also be vaccinated against Covid-19. These industries include schools and healthcare.

Frequently Asked Questions

Does New Mexico require you to titer test?

New Mexico titer test regulations generally do not require titer testing for employment. However, there are some exceptions for healthcare workers and employees in high-risk industries. These workers must be vaccinated against or show proof of immunity to rubella.

Vaccinations are not generally mandatory for employment in New Mexico. However, certain employers may require vaccinations to ensure immunity to contagious diseases among their staff. If that is the case, titer tests can be used by employees to prove immunity.

Although New Mexico antibody test regulations and vaccination laws do not usually mandate titer tests and vaccines, employers may wish to follow federal guidelines.

What is different from federal guidelines?

The federal Centers for Disease Control and Prevention (CDC) and the Occupational Safety and Health Administration (OSHA) do not require titer tests and vaccines but offer recommendations. Recommendations set by OSHA and the CDC are specifically for healthcare workers and other employees that work in industries with a high risk for communicable diseases.

According to the CDC, healthcare workers are employees that work directly with patients or handle materials with the potential to spread infection. These workers include physicians, nurses, volunteers, students, dentists, administrative staff, laboratory techs, and pharmacists.

The CDC recommends these employees have immunity to the following contagious diseases:

Measles, mumps, rubella (MMR)
Hepatitis B
Tetanus, diphtheria, pertussis (Tdap)

In addition to CDC recommendations, OSHA recommends that healthcare workers and high-risk employees be vaccinated against COVID-19.

What do titer tests test for?

Titer tests analyze blood for the presence of antibodies of specific contagious diseases. The presence of antibodies determines a person's immunity to the disease. These diseases include hepatitis, measles, mumps, rubella, tetanus, pertussis, meningitis, and COVID-19.

What does a positive titer test mean?

A titer test checks for the presence of antibodies in the blood, and a positive test means that antibodies are present. This means that an individual has immunity to that disease. Negative tests mean that person is not immune.

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.
