COVID-19 At-Home Antigen Test Kits

When to Use At-Home Tests

COVID-19 testing is not required. SFDPH recommends usage of at-home tests when:

  • Returning to schools if exhibiting symptoms
  • Returning to school from isolation on or after 5 days, and 
  • Screening after holidays, even if you are not symptomatic
  • If your student gets sick with symptoms (like cough and fever), stay home and use your tests to see if it is COVID-19.
  • If your student is exposed to someone with COVID-19, stay home and use your tests on or after day 5. 

SFUSD offers self-swab test kits at a limited number of sites. These test results will be returned within 24 to 48 hours. 

For those experiencing COVID-19 symptoms, please do not come into school

You can also access testing at locations throughout San Francisco, which includes your primary health care provider and community and public testing sites.
