Some Pennsylvania 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 Pennsylvania Regulations

Pennsylvania Antibody Testing Regulations

Currently, there are no Pennsylvania antibody test regulations that require the general public to undergo titer testing for any specific reason. However, it's important to understand that certain industry employees may be required to comply with immunization requirements where titer testing can possibly be used to demonstrate immunity.

A positive Pennsylvania titer test indicates that a subject's blood sample features enough antibodies to declare them immune against a variety of infectious pathogens, including hepatitis B, measles, mumps, and rubella. If an employee can demonstrate immunity, certain vaccination requirements can potentially be avoided, so long as workplace policy as well as Pennsylvania titer test regulations and immunization laws allow.

In the age of ongoing COVID-19 regulations and mandates, it's critical for employers and employers to also routinely assess workplace regulations to ensure compliance with any new updates and to understand if Pennsylvania titer tests can be used to demonstrate immunity.

Pennsylvania Antibody Industry Regulations

In the state of Pennsylvania, certain employee types, including those part of the healthcare industry, face certain immunization requirements to maintain employment. As an example, under Pennsylvania law, long-term care facility employees must maintain annual immunizations against both influenza and the pneumococcal virus. A long-term facility employer will be required to continuously maintain employee records of immunization to remain in compliance.

Furthermore, the state of Pennsylvania has created special provisions regarding immunizations and birth center employees. According to Pennsylvania Code § 501.41, part of the pre-employment examination policy for birth center employees must include the results of a Pennsylvania titer test that has screened for rubella in addition to a tuberculin skin test. This test will be used to indicate whether an employee holds immunity against rubella due to previous vaccination or prior infection.

Outside of the Pennsylvania healthcare industries, there typically aren't many more immunization requirements employees will have to worry about. However, it's important to note that most college students, especially those enrolling in medical programs, may be required to demonstrate immunity against various infectious diseases by either vaccine records or Pennsylvania titer test results.

Frequently Asked Questions

Does Pennsylvania require you to titer test?

No state law or regulation specifically mandates Pennsylvania titer testing of its residents. However, industries such as healthcare may mandate immunization requirements where titer testing can possibly be used as proof of immunity.

What does a positive test mean in Pennsylvania?

A positive Pennsylvania titer test indicates that a certain amount of antibodies surpassing a set value has been detected signaling immunity against a certain infectious pathogen, such as hepatitis B or varicella-zoster (chickenpox).

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.
