Overview of Maryland Regulations

Maryland Antibody Industry Regulations

A positive Maryland antibody test means that antibodies produced by the body's immune system or previous vaccination have been detected in a blood sample, which indicates possible immunity against diseases including measles, mumps, and rubella. Under current law, there are no Maryland titer testing regulations that require the general public to undergo routine antibody testing.

While the state does not mandate a Maryland titer test, the same cannot be said regarding specific industry requirements. For sectors that work with high-risk Maryland residents, such as healthcare, employees may be required to meet immunization requirements established by the workplace. To demonstrate immunity, an employer will typically require proof of immunization via vaccination records or Maryland antibody testing results.

Maryland Antibody Industry Regulations

Though Maryland residents are not mandated by state law to undergo titer testing for any reason, those belonging to various job industries must remain mindful of workplace regulations. Immunization requirements established by different workplaces may require proof of immunization against various infections, including chickenpox and hepatitis B, by using vaccination records or the results of a Maryland titer test.

According to the Centers for Disease Control and Prevention (CDC), hospital workers born after 1956 working at least 20 hours each week who are newly retained as medical staff, a direct or contractual employee, or a volunteer of a hospital, must demonstrate proof of immunization against rubella and measles.

With the continuing evolution of the COVID-19 pandemic, it's important for employers and employees to also remain mindful of ongoing changes to immunization requirements in the workplace. Such regulations can vary from industry to industry and should be routinely reviewed to ensure complete compliance.

Similar to measles, an employee can use vaccination records or a Maryland antibody test to demonstrate immunity.

Frequently Asked Questions

Does Maryland require you to titer test?

No state law or regulation specifically mandates Maryland titer testing of its residents, though certain industries may require employees to meet various immunization requirements. In certain instances, Maryland titer testing can be used as proof of immunity.

What does a positive test mean in Maryland?

A positive Maryland titer test indicates that a certain amount of antibodies surpassing a set value has been detected within a blood sample signaling immunity against a specific infectious pathogen such as rubella.

How often do you have to get tested in Maryland?

While Maryland does not enforce routine titer testing law, employees who are at risk of infections, such as those part of the healthcare industry, may want to consider routine titer testing to understand ongoing levels of immunity against various infections.

Why are antibody tests important?

Antibody testing can determine if a person has immunity against certain diseases. This process may be necessary for those who are unsure of their vaccination status, or for employers that require proof of immunity to diseases. Testing for antibodies in the blood is also commonly performed to avoid unnecessary vaccinations for someone who has already developed immunity.

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.
