Arizona Titer Testing

Many industries, such as healthcare or education, will require proof of vaccination or immunity against certain diseases. Some people may have no proof of their immunity, or they may be uncertain about their vaccination status. For people who need to provide proof of immunity to an employer in Arizona, Health Street offers antibody testing that can identify if a person has previously been infected with a specific disease or virus. We offer a variety of antibody testing services that can test for different antibodies, such as varicella (Chickenpox), hepatitis A, hepatitis B, hepatitis C, measles, mumps, rubella, or COVID-19.

Frequently Asked Questions

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.

Arizona Antibody Testing Regulations

From university enrollment to job employment, organizations may require proof of immunity via antibody testing or vaccination for various infectious diseases, including measles, mumps, and now more recently, COVID-19. For Arizona residents or employers looking to use titer testing services, it’s important to remain mindful of any Arizona antibody test regulations.

Regarding government policy, there are currently no state laws or regulations that require residents to undergo Arizona antibody testing for any reason. Although there aren’t Arizona titer test regulations, it’s important to remain mindful of individual employer COVID-19 vaccine mandates and other vaccine requirements that may affect you.

Whether you need or want to undergo titer testing, results can reveal previous infections and potentially remove the requirement for various vaccination types. In the state of Arizona, a positive titer test means that antibodies produced by a certain infectious antigen have been detected within the body and allows doctors to determine whether you are immune from future infections.

Arizona Antibody Industry Regulations

While there are no government laws or regulations that mandate titer testing for the general public, it’s important to consider requirements on an industry-specific level. According to the Centers for Disease Control and Prevention (CDC), the state of Arizona currently has no requirement of vaccination and/or need to demonstrate immunity of diseases with titer testing for healthcare workers.

However, with the ongoing COVID-19 public health emergency, it’s highly recommended that healthcare workers continue to comply with vaccine mandates within their state. The Arizona government recently passed Executive Order 2021-21 which bans all employers except healthcare employers from mandating COVID-19 vaccines, but allows healthcare institutions to decide themselves if they’ll mandate immunization among employees.

Arizona antibody test regulations and immunization law state that employers must make hepatitis B testing and vaccines available to all employees that have exposure at their place of work. This holds true even if the employee declines but then changes their mind while they’re still covered. According to Arizona Revised Statutes Title 23. Labor § 23-1043.03, any employee who claims “a condition, infection, disease or disability” due to hepatitis C exposure while on the job must inform their employer about the details of this exposure. They must then have an antibody test to check for hepatitis C. Although not specifically related to employment industries, university students must also remain mindful of Arizona titer test regulations. For instance, some Arizona universities require students to show proof of antibody testing and/or immunization from diseases including hepatitis B and chickenpox in order to enroll.
