Check your immune

response against COVID-19

COVID-19 Neutralizing Antibody Test

Test for antibodies that neutralize SARS-CoV-2, the virus that causes COVID-19. This is the only FDA EUA approved test to determine whether you have functional neutralizing antibodies. Other IgG/IgM antibody tests do not provide results on the functional or neutralizing aspect of the antibodies. Recommended for individuals post-vaccination or post-recovery from an active infection. Receive secure digital results in 3-5 business days.

Take a Neutralizing Antibody Test after your first COVID-19 vaccine dose and again after your second dose to check whether your body produced neutralizing antibodies in response to the vaccine. For a vaccine that is 95% effective, 5,000 out of every 100,000 people vaccinated won't be protected.


Were you infected with SARS-COV-2 (COVID-19)? The Neutralizing Antibody Test can determine your immune system's response to the infection. Experts are still learning about how long neutralizing antibodies remain in the blood after infection, and whether you are protected from reinfection in the future.

General Awareness

If you want to take a baseline test before vaccination or if you're simply curious about your immune status, you are eligible for the test. The Neutralizing Antibody Test is available for front line workers, healthcare workers, educators, and the general public.



SARS-CoV-2 has a biological key, called a spike protein, that allows it to bind to receptors on the cell membrane and unlock the door to human cells. 

Once inside of cells, the virus replicates and causes infection such as COVID-19.

The immune system produces neutralizing antibodies which bind to the viral spike protein and block its ability to function as a key.

Neutralized SARS-CoV-2 can no longer enter human cells or cause infection.
