FDA issues emergency use authorization for Yale's saliva coronavirus test

How it works: The test, deemed less expensive and less invasive than traditional methods, does not require specific swabs or collection devices to gather samples. Instead, a patient's saliva can be collected in any sterile container, which could cut down on the use of medical supplies the FDA says are in shortage.

• Samples are also collected under the observation of a health care professional, meaning the method could also lower the risk posed to workers who handle samples.

What they're saying: "Because this test does not rely on any proprietary equipment from Yale and can use a variety of commercially available testing components, it can be assembled and used in high-complexity labs throughout the country," the FDA said.

The big picture: This is the fifth test the FDA has allowed that uses saliva as a sample for testing.

• SalivaDirect is being further validated as a test for asymptomatic people through a program that tests players and staff from the NBA, YaleNews writes.
