COVID-19: What you need to know about testing

To meet state guidelines, the County of San Mateo needs to administer about 1,200 tests per day, through hospitals, private testing companies, and the free program available through Verily. Please check with your company and/or primary provider for other options.

Project Baseline

Testing is free and available to anyone without restriction, although an appointment is required in advance. To make an appointment, residents can visit Project Baseline’s website (use this hyperlink: https://bit.ly/2xk73OL). Registration opens 72 hours before testing dates. Remember to bring your photo ID and the reference ID from your confirmation email.
If you don't have access to the internet, an on-site volunteer may be able to help you register and get tested. 

UPDATE: Those being tested can now swab their nostrils themselves. Watch the video above or click on the PDF at the bottom of this page for details about the testing procedure.

After being tested, residents will receive results and other information by email. San Mateo County Health will reach out to residents who test positive.
