What To Know About COVID-19 Testing
Centers for Disease Control and Prevention (CDC) defines two kinds of tests that are available for COVID-19: viral tests and antibody tests.
A viral test tells you if you have a current infection.
An antibody test tells you that you had a previous infection.
An antibody test may not be able to show if you have a current infection, because it can take 1-3 weeks after Infection to make antibodies. We do not know yet if having antibodies to the virus can protect someone from getting infected with the virus again, or how long that protection might last.
