Overview of Connecticut Regulations

Connecticut Antibody Test Regulations

There are few Connecticut titer test regulations and vaccination laws. In most cases, Connecticut does not require titer testing or vaccinations.

Connecticut antibody test regulations do not mandate that employers require their workers to submit proof of immunity or vaccination for influenza, MMR, varicella, or pneumococcal pneumonia. Industries like healthcare facilities, however, have policies regarding hepatitis B and COVID-19 vaccinations.

Connecticut Antibody Industry Regulations

Connecticut titer test regulations and vaccination laws comply with federal OSHA standards for all employees with potential exposures to blood or other infectious materials. These employees must be offered the hepatitis B vaccine and vaccine series by the employer.

As of December 28, 2021, the Centers for Medicare & Medicaid Services (CMS) issued a COVID-19 vaccine mandate for healthcare facilities that participate in Medicare and Medicaid. This includes hospitals, ambulatory surgery centers, long-term care, home health, and dialysis facilities. This mandate is required for employees, volunteers, students, trainees, and anyone involved with patient care.

Although Connecticut titer test regulations and vaccination laws are geared toward healthcare workers, other employers might consider developing titer test regulations to prevent disease outbreaks. These industries include education, correctional facilities, construction, and any industry at risk for spreading contagious diseases.

Relevant Connecticut Laws, Acts, and Legislation

Sec. 31-372-101-1910. Safety and health standards: Adopted from the U.S. Department of Labor OSHA Safety and Health Standards 29 CFR § 1910, this requires employers to provide the hepatitis B vaccine to employees with occupational exposure.
Executive Order No. 13D: Connecticut state employees, PreK-12 school staff, and workers at childcare facilities are required to be vaccinated for COVID-19 or submit to weekly testing.
Connecticut healthcare employees in hospitals and long-term care facilities must be vaccinated against COVID-19 with no option for weekly testing instead of vaccination. This law also applies to employees who regularly visit these healthcare facilities.
Medicare and Medicaid healthcare facilities in Connecticut must comply with a vaccination rate of 100 percent or risk being removed from Medicare and Medicaid programs.

Frequently Asked Questions

What do titer tests test for?

In Connecticut, titer tests are blood tests analyzed in a lab that look for the presence of antibodies for specific diseases in the blood. Common Connecticut titer tests include COVID-19, MMR, varicella, pneumococcal pneumonia, and hepatitis A, B, and C.

Does Connecticut require you to test?

There are no Connecticut antibody testing regulations mandating titer testing. However, there are vaccination laws for healthcare workers regarding hepatitis B and COVID-19. Employees in PreK-12 schools are also required to receive a COVID-19 vaccine but may opt out with weekly testing. Titer testing for those who are not vaccinated could prove immunity to the virus.

Why are antibody tests (titer tests) important?

Positive titer tests prove immunity to a particular contagious disease. Negative tests show no immunity and vaccination should be considered. Titer testing benefits employers by preventing disease outbreaks in the workplace, and they benefit employees by not requiring duplicate or unnecessary vaccinations.

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.
