Here is a list of Bay Area locations where coronavirus testing is available and who can get it. Many sites require a doctor’s order.

See an interactive map of Bay Area COVID-19 testing sites that don’t require a doctor’s referral here, including information on if it is appointment-only and has drive-through testing.

Though testing capacity is rising, tests are still limited and are being prioritized for the sickest and highest-risk patients. The amount of time it takes to get results back varies. The test entails taking a sample from a patient, which can be uncomfortable because a swab goes up the nose or down the throat. Before you seek out a test, read our detailed FAQ on SFChronicle.com on whether you should get tested.

Following the protests spurred from the death of George Floyd, there’s concern that people who congregated in protest could have spread the virus among each other. Because of that a free, pop-up testing location at the Cathedral of St. Mary at 1111 Gough St. in San Francisco opened June 6 for anyone to get swabbed for COVID-19, including those who have gathered in mass demonstrations recently — even if they are showing no symptoms of infection. The city is directing anyone who wants a test at the mobile site to sign up at www.projectbaseline.com/study/covid-19.

Alameda County has created a COVID-19 Testing Task Force to develop and implement a coordinated testing program and has shared a list of testing locations through the East Bay county. Find the locations, times and other details at www.acphd.org.

• Brown & Toland Physicians is doing drive-through testing by appointment at the CPMC Pacific Heights campus in San Francisco. Sutter is providing the space and Brown & Toland staff are collecting the samples and notifying patients of the results. Testing is for Brown & Toland and Sutter health care workers and patients who are symptomatic. Patients must first consult with their primary care physician, who must then refer them for testing. Samples are sent to LabCorp and results can take three to five days. The site is open Monday to Friday, 9 a.m. to 4 p.m., and Saturday from 9 a.m. to 1 p.m.

• Carbon Health, a San Francisco operator of primary care and urgent care clinics, is doing testing at its urgent care locations in the Bay Area and Los Angeles. There are nine locations in the Bay Area. Anyone showing symptoms or at-risk for exposure, including essential workers, can get a test, which must be ordered by a Carbon Health provider. Results can be as fast as same-day or up to five days, depending on the lab company.

For locations and hours, go to https://carbonhealth.com/locations.

• CityTestSF, a collaboration between the city of San Francisco, local tech companies and medical providers has two sites. Both are by appointment only. To schedule appointments, see www.sf.gov/citytestsf.

One site, at Piers 30-32, is a drive-through site run by Carbon Health and Color Genomics and serves essential workers with symptoms. A doctor’s note is not needed.

A second, at 600 7th St., is a drive-through site operated by One Medical and Verily. It is open to any San Francisco resident experiencing COVID-19 symptoms. Visit www.projectbaseline.com/COVID19 to learn more.

• John Muir Health is doing testing at four urgent care centers in the Bay Area: Berkeley, Brentwood, Pleasanton and Walnut Creek. Patients should call their primary care physician first, and if they don’t have one they should call an urgent care center. Patients must have an order from a John Muir Health-affiliated doctor to get a test. Once approved, each patient will receive an appointment at one of the urgent care centers, ideally the one closest to them. Testing is also available for high-risk patients at John Muir’s Concord and Walnut Creek emergency departments if they meet screening criteria and have respiratory symptoms. Results take four to five days.

• Kaiser Permanente has drive-through testing at its San Francisco Medical Center on Geary Boulevard and other locations, but it declined to specify where because patients have to be referred by their doctor. After being referred, the patient will receive a time and location for drive-through testing. You must be a Kaiser member. In Northern California, results take 24 hours or less.

• Forward, a network of primary care centers headquartered in San Francisco, is offering testing for its members at its locations in Northern and Southern California, New York and Washington, D.C. Its Northern California clinic is in San Francisco’s Financial District. Patients are encouraged to first use the remote assessment feature in the Forward app so a care team can assess who may have the virus. Those whose remote assessment indicates they are most in need are scheduled for testing. It is available for Forward members only, but the company expects to expand the service to non-Forward members later this week. Results come back in 36 to 48 hours.

• Cal State East Bay is doing free testing, giving priority to first responders, health care workers and people who meet certain criteria, including symptoms of fever and shortness of breath and recent travel. Testing is provided by the city of Hayward, which originally opened the site at Hayward Fire Station 7. Results come back in as little as six hours, or in most cases the next day. Call 510-293-8617 for more information.

• North East Medical Services is conducting drive-through testing at four sites: 211 Eastmoor Ave., Daly City, weekdays from 3 to 4 p.m.; 1870 Lundy Ave., San Jose, 2 to 3 p.m.; 1450 Noriega St., San Francisco, 2 to 3 p.m.; 735 Vallejo St., San Francisco, 3 to 4 p.m. Testing is limited to North East Medical Services patients who are symptomatic and by appointment only by calling 415-391-9686, (650) 550-3923 or (408) 573-9686.

• One Medical, the San Francisco-based chain of primary care centers, is doing testing for its members who meet testing criteria in San Francisco, the East Bay, South Bay and North Bay. Patients must first be assessed by a virtual care team. One Medical is no longer requiring that patients show COVID-19 symptoms; asymptomatic people who have been in contact with someone who tested positive for the coronavirus or are concerned about interacting with a high-risk individual can now get tested. If they are found to be a good candidate for testing, a doctor must approve the order before giving the patient a location and time to have a sample collected. Results come back in two to three days. Members of the general public can get tested by calling 888-ONE-MED1 to sign up for a free trial membership.

• Stanford Medicine has drive-through testing for patients who have been referred by a physician. The patient makes an appointment to go to the drive-through test at Stanford Express Care’s Hoover Pavilion location in Palo Alto, seven days a week, from 9 a.m. to 6 p.m. Patients are notified of results within 24 hours.

• Sutter Health is conducting drive-through testing in some locations. Only patients with a doctor’s order can get tested. Patients experiencing symptoms must schedule a video visit or call their doctor to receive guidance and see if they meet the criteria for testing. People with mild or moderate symptoms are asked to stay home to reduce further exposure.

• UCSF is testing hospitalized patients, emergency department patients and other patients who have passed a screening for symptoms. Patients who are not hospitalized should speak to their doctor first. A doctor’s order is required. Only UCSF employees and UCSF patients are being tested right now due to limited testing supplies.

• Verily, the life sciences arm of Google, is conducting tests in Santa Clara, San Mateo and Sacramento counties and Lake Elsinore (Riverside County). The initiative, called Project Baseline, requires people to go through an online screening before getting tested; the physician network PWNHealth approves testing and provides post-test consults. Nurses and other health care personnel from the health tech company Hawthorne Effect and Elligo, a research firm, do the specimen collection. Tests are processed by Quest, and results can take several days.

Two new coronavirus testing sites will open May 18 in East Palo Alto and Daly City on a rotating schedule at the San Mateo County Event Center on Mondays and Tuesdays, at the old Serramonte High School campus in Daly City on Wednesdays and Thursdays, and at the YMCA in East Palo Alto on Fridays and Saturdays. Testing will be free and available to anyone who has made an appointment in advance, county officials said.

• Dignity Health-GoHealth Urgent Care is conducting tests for anyone even if you don’t have insurance at five centers in Mill Valley, the Castro, Piedmont (Oakland), San Bruno and Redwood City. Hours are 8 a.m. to 8 p.m. Monday to Friday and 9 a.m. to 5 p.m. on weekends. Schedule a virtual screening process before coming in to be tested.
