Diagnostic testing for COVID-19 is critical to tracking the virus, understanding epidemiology, informing case management, and to suppressing transmission. This document describes the strategic use of diagnostic testing in different transmission scenarios of the COVID-19 outbreak, from no cases to community transmission, including how testing might be rationalized when lack of reagents or testing capacity necessitates prioritization of certain populations or individuals for testing.
