Now available - COVID-19 Anitbody Testing


Antibody or serology tests look for antibodies in your blood to determine if you had a past infection with the virus that causes COVID-19.

  • Antibodies are proteins created by your body’s immune system soon after you have been infected or vaccinated.
  • Antibodies help you fight off infections and can protect you from getting that disease again. How long this protection may last is different for each disease and each person.

Antibody tests should not be used to diagnose a current infection with the virus that causes COVID-19, except in instances in which viral testing is delayed. An antibody test may not show if you have a current infection because it can take 1–3 weeks after the infection for your body to make antibodies.

Whether you test positive or negative for COVID-19 on a viral or an antibody test, you still should take steps to protect yourself and others.

We do not know how much protection (immunity) antibodies to the virus might provide against getting infected again. Confirmed and suspected cases of reinfection have been reported, but remain rare. Scientists are still working to understand this.


You may have had COVID-19 with mild or even no symptoms and not even realized it. The IgG antibody test can help identify anyone who may have been exposed to or contracted SARS-CoV-2 or the Coronavirus and may have developed antibodies. Your IgG antibody status may help you be able to resume work and other daily activities. Additionally, now with the high rate of vaccinations, many countries require an antibody test in order to gain access to the country. Know before you travel if the vaccine is still viable in your system. COVID-19 antibody tests have the potential to play a critical role in helping our communities move forward.

The CDC estimated asymptomatic transmission could be as high as 25%
