Who Can Get Tested?

Adults age 18 and over can schedule a test Tuesdays through Saturdays at the San Mateo County Event Center or at a rotating series of neighborhood locations. Days and times are listed below.

If you are interested in being tested, you may also contact your health care provider – just as you would with any other health concern. One local option is Stanford Health Care, which offers testing for both Stanford patients and the public. 

To find additional local testing sites, visit the state’s testing site locator. Patients with health insurance should check whether the cost of the test can be covered by insurance.

Note: Testing is now available for children ages 5 to 17. Schedule an appointment and learn more.

What is COVID-19?

COVID-19 is a severe respiratory syndrome and infectious disease. Its symptoms include but are not limited to fever, cough, shortness of breath, loss of taste or smell. However, not all people have symptoms when they have COVID-19.

A Note on Site-Specific Testing

Working with cities and local partners, the County is also providing testing to local communities at pop-up neighborhood testing sites in priority locations as identified by Public Health. Some residents may receive information about the availability of such sites through targeted outreach in their neighborhoods and communities.

After a Test: What’s Next?

Most results are returned in 72 hours.

If your first COVID test is negative, you should get tested again if you:

  • Are concerned about possible exposure
  • Have spent time with people outside your household
  • Have had exposure to someone with confirmed or possible COVID-19
  • Have symptoms
  • Work in a congregate setting like a nursing home or shelter are planning to visit someone at high risk for severe COVID-19 illness

If you test positive for COVID-19, a contact tracer with San Mateo County Health will contact you. Certain support services may be available for those who qualify.

If you do test positive, view home isolation instructions in multiple languages.

Why is COVID-19 testing important?

The results of your COVID-19 test, along with other information, can help you and your health care provider make informed decisions about your care.

  • Being tested for COVID-19 may help limit the spread of COVID-19 to your family and others in your community.
  • Widespread testing also helps inform the public health response, allowing health care professionals to quickly discover patterns and respond to outbreaks.
  • Testing also plays a key role in determining what sectors of the economy are permitted to open – and help all of us get back to work, to school and to enjoy everyday life safely.
  • Widespread testing along with a low rate of positive tests helps our community comeback from COVID-19.
