Oregon Titer Testing

Some Oregon 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 Oregon Regulations

Oregon Antibody Testing Regulations

In the state of Oregon, residents do not face any laws or regulations that mandate routine titer testing for any general reason. Though not required, Oregon titer testing is a powerful health tool to provide detailed insight into an individual's level of immunity against a variety of infectious pathogens, including different varieties of hepatitis. An Oregon antibody test will come back positive when enough antibodies have been detected in a blood sample to signal immunity against a specific disease.

While the general public does not face any Oregon titer testing regulations, employees belonging to certain industries should still remain mindful of immunization requirements. Workplaces that generally possess a higher risk of infections, such as healthcare facilities, will commonly require certain immunizations for employees. Likewise, with ongoing changes in workplace policies regarding COVID-19 prevention, it's important for employees to routinely assess current regulations to ensure ongoing compliance with Oregon titer testing and immunization requirements.

Oregon Antibody Industry Regulations

While there are no Oregon antibody industry laws or regulations that mandate the routine titer testing of state residents, certain employee types may still face immunization requirements in the workplace. Though many states across the country mandate specific immunizations, such as MMR and chickenpox vaccinations, the state of Oregon does not enforce any strict requirements for employees in regards to immunizations.

For instance, while healthcare industry employers do not have any strict immunization requirements, there are certain requirements that the employers themselves must still meet. Oregon state law mandates that an employer of a healthcare worker at risk of contracting an infectious disease must provide the worker with preventive immunizations if requested. These preventive immunizations must be provided by the employer at no cost to the worker and can't be used as a condition for employment unless federal or state regulations say so.

While not immediately related to employees, it's important to also note that many Oregon colleges and universities will also enforce immunization requirements for students, including those enrolling in medical programs. When faced with such mandates, it's essential to consult with university policy to understand which immunization documentation must be provided and if Oregon titer testing can be used to demonstrate immunity.

Frequently Asked Questions

Does Oregon require you to titer test?

No law requires Oregon antibody testing on residents for any specific reason. However, employees should always discuss any immunization and titer testing requirements with their employer to remain in compliance with workplace policy.

How often do you have to get tested?

While Oregon holds no routine titer testing laws or requirements, employees at risk of contracting infections, such as healthcare workers, should consider annual titer testing to understand their ongoing levels of immunity against various infections.

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.
