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.
