The most accurate way of determining if you have been infected with COVID-19 is via an antibody test—and even then it's not 100%. According to the
CDC, the tests check your blood by looking for antibodies, which may tell you if you had a past infection with the virus that causes COVID-19. "Antibodies are proteins that help fight off infections and can provide protection against getting that disease again (immunity)," they explain. However, antibody tests are not flawless. For example, a positive test could mean you have antibodies from an infection with a different virus from the coronavirus family. If you test negative, it could be because you are still battling the virus and haven't produced antibodies. "Some people may take even longer to develop antibodies, and some people who are infected may not ever develop antibodies," the CDC points out.
