SHIELD FAQ - What is the difference between diagnostic testing and screening?

--

The covidSHIELD test can be used for both diagnostic testing and screening.  Diagnostic tests are intended to identify current infections at the individual level and are performed when a person has signs of symptoms consistent with COVID-19, or when a person is asymptomatic but has recent known/suspected exposure to SARS-CoV-2. Screening tests are intended to identify infected persons who are asymptomatic and without known or suspected exposure to SARS-CoV-2.
