COVID-19 Antibody Test

This COVID-19 Antibody Test is designed to identify COVID-19 antibodies in the blood, which are produced as an immune response to the virus (also known as Coronavirus).

This COVID-19 Antibody Test is designed to identify COVID-19 antibodies in the blood, which are produced as an immune response to the virus (also known as Coronavirus). Note that this test is not designed to identify the presence of the virus itself, only the antibodies. If you suspect you might have COVID-19, it’s best to follow up with your healthcare provider about getting a PCR test. This COVID-19 Antibody Test is designed for those who have had, or suspect they’ve had this virus in the past and are not experiencing symptoms or those who’ve never had COVID-19 and want to know if they carry the antibodies.

How It Works

If you want to determine whether you have active Covid-19 antibodies, we make it easy. Simply add the Covid-19 antibody test to your cart, then check out. Once you’re ready to conduct the test, you can visit one of our more than 4,000 testing facilities across the country. You do not have to have an appointment for our testing facilities; instead, you can arrive at a time that’s convenient for you. Once you’re there, you can sign in and one of our qualified technicians will conduct a blood draw. Most of our patients are able to have their tests done and get out the door within just 30 minutes, allowing you to go on with the rest of your day.

When Do You Need a Covid-19 Antibody Test?

You might want to have a Covid-19 antibody test for a number of reasons.

  • You want to determine whether you may have had Covid-19 in the past, particularly if you think you may have been infected asymptomatically.
  • You want to test your antibody levels to determine how your immune response has changed over time. 
  • You are immune-compromised and want to know whether you have any antibodies to Covid-19. 
  • You have had the Covid-19 vaccine and want to see if you have antibodies that will help protect against Covid-19. 

Keep in mind that the Covid-19 antibody test does not check for an active Covid-19 infection. Instead, it checks for the presence of antibodies, which could indicate either past infection or contact with the virus or vaccination. You should not have a Covid-19 antibody test if you suspect that you have an active Covid-19 infection.

How to Interpret Your Results

When you receive your Covid-19 antibody test results, you will see three columns. The “reference” column will let you know what the normal range of Covid-19 antibodies look like for people who have been previously infected with Covid-19 or who have had a Covid-19 vaccine. The “results” column will detail the specific levels of antibodies you have in response to Covid-19. The “flag” column will let you know whether you have Covid-19 antibodies or if you have waning levels of those antibodies.

Covid-19 Antibody Test vs. MMR Immunity Test

In some cases, you may want to have an immunity test to determine whether you have long-lasting immunity from any type of vaccine. Some people may, over time, note that their immunity wanes, even if they have had a previous infection. A Covid-19 immunity test will help test your antibody levels in response to Covid-19, while an MMR immunity test will help determine whether you have immunity to measles, mumps, and rubella. It’s important to be sure that you choose the right immunity test for your needs, since you want to make sure that the test looks at the right antibodies.


  • The Covid-19 antibody test is designed to tell you if you have Covid-19 antibodies. Most people who have mounted an immune response against the disease will have some level of antibodies. However, many circumstances, including some medications, can decrease the levels of antibodies you actually have.

  • After your Covid-19 test, you can receive advice from one of our care counselors in how to interpret your results. You can also get in contact with a physician if needed.

  • As Covid-19 continues to develop, the presence or lack of antibodies may not accurately determine exactly how your body will respond to Covid-19 exposure in the future. Consult a physician for more information.
