Labs across the U.S. have processed more than 2.8 million tests for coronavirus. Public health experts believe that number is far below what is needed to accurately track and contain the spread of COVID-19. Minnesota's rate of positive tests — less than 5% — is among the lowest in the country. But based on its population, the state's 37,000-plus tests trail the national median for completed tests.
