San Mateo County announced this week that it will expand countywide COVID-19 testing through mobile sites and targeted testing in at-risk neighborhoods.

The county currently offers free COVID-19 testing through Verily’s Project Baseline program. Testing is available Tuesdays through Saturdays at the San Mateo County Event Center.

Mobile testing through Project Baseline is also available on rotation at Half Moon Bay, Daly City, San Bruno, East Palo Alto and North Fair Oaks.

“At the most fundamental level, increasing access to testing is about equity,” said Warren Slocum, President of the county’s Board of Supervisors. “We want to make sure that everyone, regardless of income or immigration status or whether they have health insurance or not, has access to a local testing site.”

The tests are free and do not require insurance, though people must schedule an appointment to get tested. Volunteers at the testing centers can also help people get registered on site.

The county also launched a new initiative which will provide targeted, neighborhood-level testing in at-risk communities where there is a spike in Covid-19 cases.

For example, East Palo Alto – which has a high case rate compared to other cities in the county – will host a free targeted testing site from 4 p.m. to 7 p.m. on Friday, at 1600 Bay Road, East Palo Alto. No appointment, pre-registration or citizenship information is required for testing.

County Manager Mike Callagy encouraged people to get tested.

“We want to see every available testing appointment filled every single day,” Callagy said. “The testing pipeline is open, the turnaround time is fine and we need to get people tested.”
