What can an antibody test tell me?

Antibody tests look for markers of past infection with SARS-CoV-2. They are not used to tell whether you are sick with COVID-19 at this moment. Because of this limitation, antibody tests cannot tell the average person too much about their current circumstances, but they can help public health researchers learn about how much COVID-19 has spread through a city, state, country, etc. You can learn more about antibody tests and their uses here: https://www.centerforhealthsecurity.org/covid-19TestingToolkit/testing-basics/types-of-COVID-19-tests/serology-tests.html
