Verily, an Alphabet subsidiary, is collaborating with the California Governor’s office, federal, state and local public health authorities, to help people in the Bay Area with COVID-19 screening.

Through its new site, which is part of a larger health initiative called Project Baseline, people residing in California can sign up to get tested for COVID-19 at no charge. At present, it’s only available to folks living in Santa Clara County and San Mateo County.
