The United States Food and Drug Administration (FDA) has approved a new coronavirus test that costs less than others and is simple to use. The 15-minute test from Abbott Laboratories will sell for $5. It does not require special computer equipment to get results. The self-contained test is about the size of a credit card. It uses the same technology as some flu and pregnancy tests. The FDA noted that Abbott’s test could be used in a doctor’s office, emergency room or some schools. “Given the simple nature of this test, it is likely that these tests could be made broadly available,” the FDA said. The agency also recently approved a saliva test from Yale University. Both newly approved tests have limitations, like requiring medical administration.
