• COVID-19 Testing


Who Should Get Tested

Individuals falling within the following categories should seek COVID-19 testing:

Prioritizing testing for these groups helps ensure those patients with the highest risk of infection are quickly identified and can isolate.

Where to Get Tested

If you have any form of health insurance, your first stop for testing should be your primary care physician or local medical clinic. This is the best way to get follow-up care right away, and you may also get your results faster. 

For Health Plan of San Mateo members: contact your primary care provider (PCP), or HPSM’s Nurse Advice Line at 833-846-8773 if you don’t have a PCP. For more information, visit HPSM.

Stanford Medicine offers testing options for both Stanford patients and the public generally. First responders and essential workers will be given priority for testing and results delivery, regardless whether the individual is a Stanford patient. Visit Stanford Medicine's page for more information.

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.
