The Costa Mesa site will open on Wednesday, August 26, and will operate Monday through Friday from 7 a.m. to 3 p.m.

The second supersite comes just six weeks after the county opened the Anaheim super site at the Anaheim Convention Center.

“I’m so pleased that we are opening this new test site to offer additional convenient access to testing for our residents, particularly for those within my district,” said Orange County Board of Supervisors Chairwoman Michelle Steel, Second District.

“Testing is one of the keys to our ability to slow the spread of the virus and still go about our business of getting back to work and enjoying life in our community.”

The site, 360 Clinic, will provide no-out-of-pocket cost testing leveraging personal insurance reimbursements and federal government assistance for the uninsured, with additional financial support from the County.

“This new site in Costa Mesa bolsters our local testing capacity, enabling more symptomatic and asymptomatic Orange County residents within priority groups, to access free contactless testing with quick turnaround times on results,” said Vice Chairman Andrew Do, First District.

Tests will be available for individuals prioritized for testing by the California Department of Public Health:

  • People with symptoms
  • Close contacts with people known to have COVID-19
  • Healthcare workers, first responders
  • Residents and employees of congregate living facilities
  • Essential workers (grocery store, food supply, utility workers, public employees and teachers)

“There are three key messages we want to convey to people who may have been reluctant to get tests – particularly at our super sites,” said Third District Supervisor Donald P. Wagner.

“1. Wait times in your car are generally no more than 30 minutes. 2. The tests are self- administered, safe, easy and pain-free. 3. Results are available in 24 to 48 hours so you can quickly determine whether you test positive for COVID-19 or not and plan accordingly.”

Participants will be asked to provide their contact information along with their health insurance information, if available, when selecting their appointment date and time.
