COVID-19 Antigen Self-Test Expiration Extension

If you have a COVID-19 home antigen test that is past its expiration date, you may still be able to use it. The Los Angeles County Department of Public Health supports the California Department of Public Health’s endorsement of the emergency use of COVID-19 antigen self-tests beyond their expiration date.
