While government employees, students and the general public had to wait in line for hours in the beginning of the pandemic, at-home test kits make it easy to diagnose for the novel coronavirus in less than 30 minutes. The nasopharyngeal tract likely has (1) active virus replication and (2) enough virus to be detected in test kits. A systematic review of the accuracy of covid-19 tests reported false negative rates of between 2% and 29% (equating to sensitivity of 71-98%), based on negative RT-PCR tests which were positive on repeat testing.
