Why Use a COVID-19 Self-Test?

Why should I use an at-home rapid antigen test?


COVID-19 self-testing is one of the actions you can take to protect yourself and your close contacts. To protect yourself and others against COVID-19, you should:

  • Get the COVID19 vaccine and your booster
  • Wear a mask
  • Practice social distancing, whenever possible


Are COVID-19 self-tests difficult to use?

You can take a self-test at home or virtually anywhere, they are easy to use, and produce quick results.


Some kits come with two test cards. Can I use those for two people?

Each kit is meant for only one person, whether the kit contains one test or two tests. When using a kit that contains two tests: if your first test is negative, use the second test 24-48 hours later, per manufacturer’s instructions. 


When should I use the self-test?

  • Use a self-test if you are feeling sick, to quickly learn if you might have COVID-19
  • Use a self-test after you’re notified that you have been exposed to someone with COVID-19. If it is negative, you can repeat the test five days after exposure
  • Use a self-test before going to indoor gatherings to evaluate your risk of spreading COVID-19
