MMR Immunity Test (Measles, Mumps, Rubella)


This MMR Immunity Test will determine your immunity (or lack thereof) to measles, mumps, and rubella. Immunity can come by way of vaccination (most common) or previous infection. While vaccination has all but eradicated these illnesses in much of the world, small pockets of infection do pop up sporadically. For this reason, most schools and many places of business will require MMR immunity. If you are not yet immune, you’ll want to talk with your physician about getting an MMR vaccine. If you are unsure whether or not you are immune or have been vaccinated, this MMR Immunity Test can put your mind at ease.

When Do You Need an MMR Immunity Test?

An MMR Immunity Test can help you determine whether you still have immunity to measles, mumps, and rubella. Typically, immunity is developed either through prior infection or through vaccination. You may need to check your MMR immunity for several reasons. 

  • Your employer requires it. Some employers may require you to show that you are immune to measles, mumps, and rubella before beginning employment. This is particularly common if you work in a medical setting. 
  • You have had medical treatments that may have caused you to lose your immunity to measles, mumps, and rubella. Chemotherapy, for example, may destroy some immunity.
  • You will be traveling to an area with a measles outbreak, or live in an area with an outbreak, and want to be sure that you’re protected. 
  • You want to check your immunity to make sure that you do not need to update your vaccines. 

Your doctor may recommend that you have an MMR immunity test to check your immunity if you have any chance of exposure to measles, mumps, or rubella. 

Interpreting Your Results

When you receive your MMR Immunity Test Results, you will note three columns. One column will show the normal range for the test, so you can understand what indicators the test looks for. Next, you’ll see the results column, which will offer the specific numeric results of your MMR test. Finally, the flag column will lay out whether you still show signs of immunity to measles, mumps, and rubella. 

MMR Immunity Test vs. Covid-19 Antibody Test

Many types of immunity tests can help you determine how susceptible you are to a specific type of illness. Some people are now taking Covid-19 antibody tests to help determine what immunity they might have to Covid-19, for example. Immunity tests help give you a clearer look at what immunity you might have to those illnesses. You may need to take those tests to determine whether you need to be vaccinated for specific conditions or illnesses. Take the test related to the vaccine that you have questions about. If you want to know if you have immunity to measles, mumps, and/or rubella based on either vaccination or prior infection, an MMR Immunity Test can answer your questions.


  • We will offer you access to care counselors, who can provide you with more information about how to interpret your results. If you need additional medical care, including an MMR vaccine, contact a physician, or we can connect you with a physician in our network.

  • You may need an MMR immunity test because a doctor or employer orders one, or because you want to know if you need to update your MMR vaccine.

  • Your doctor can help you decide what vaccines you may need based on your activities, risk level, and immunity levels.
