Do I always need to perform two tests?

The QuickVue At-Home OTC COVID-19 Test is intended to be used for serial testing of asymptomatic individuals or used twice by the same individual over two or three days with at least 24 hours (and no more than 48 hours) between tests or once by symptomatic individuals within the first six days of symptom onset. By testing more frequently, you may detect COVID-19 more quickly and reduce spread of infection.
