FDA says rapid Covid antigen tests may be less sensitive in detecting 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. In people with confirmed COVID-19, antigen tests correctly identified COVID-19 infection in an average of 73% of people with symptoms, compared to 55% of people without symptoms.
