COVID-19

*Disclaimer: Much of this content is now outdated. It was developed early in the pandemic to communicate the basics of COVID-19 testing when the main question we were being asked was “should I get an antibody test or a molecular test?” Back then, we had access to antibody or PCR tests. The distinction of antigen versus PCR or NAAT did not become relevant until months later when additional assays for SARS-CoV-2 became available.
