Diagnostic testing has been an indispensable tool in the fight against the COVID-19 pandemic. Since the infectious period is limited to the first five to ten days of the infection, prompt results are needed to change behaviors to limit transmission. Laboratory testing has allowed high sensitivity for patients coming in but can sometimes have extended turn-around times. For many patients with milder symptoms, they may show up at physician offices and urgent care so point-of-care molecular tests may better satisfy that population. Meanwhile, routine serial antigen tests have allowed schools and businesses to get back to face-to-face meetings and travel to resume.
