Priced at $149, the At-Home Saliva RT-PCT tests are being sold at contactless kiosks in both of the airport's terminals, airport officials said.
It is the first US airport to offer Covid-19 tests in vending machines, according to a press release from the airport.
"Oakland international Airport is helping our travelers navigate this global pandemic by providing more testing options," said Bryant L. Francis, Port of Oakland Aviation Director in a statement.
He said travelers still need to be aware of quarantine rules and restrictions at their destinations.
The self-administered tests were designed by digital health company Wellness 4 Humanity, the release said.
Travelers will collect a saliva sample and then send it in for testing via FedEx. They'll get the results back through an app on their phone.
Airport spokesman Roberto Bernardo told CNN that the tests are designed for travelers flying into Oakland after a trip. Other passengers should get tested by their primary care provider at least three days before their flight.
"These saliva at-home test kits are for those who are arriving at the airport," Bernardo said in an email. "We know there are folks who have concern that they may have been exposed to COVID during their travels. They can use these tests when get home."
The University of California Santa Barbara has put in similar vending machines on campus to give students and staff better access to free tests.
