Antibody or serology tests look for antibodies in your blood that fight the virus that causes COVID-19.

• Antibodies are proteins created by your immune system that help you fight off infections. They are made after you have been infected or have been vaccinated against an infection.

• Vaccination is a safe, effective way to teach your body to create antibodies.

• Antibodies can protect you from getting those infections for some period of time afterward. How long this protection lasts is different for each disease and each person.

• Antibody tests should generally not be used to diagnose a current infection with the virus that causes COVID-19. An antibody test may not show if you have a current infection because it can take 1 to 3 weeks after the infection for your body to make antibodies.
