Federal health officials on Friday approved a coronavirus test that can provide results in less than 15 minutes, using the same technology that powers some rapid flu tests.

Teased by Vice President Mike Pence in a Thursday press briefing, the new diagnostic test could accelerate testing in the United States, allowing for rapid results in doctors’ offices. But shortages of critical equipment used to collect patient specimens, like masks and swabs, could blunt its impact.
 
The US Food and Drug Administration authorized the test for emergency use, signaling that federal regulators were satisfied with the test’s validation data and believe its benefits outweigh any risks, such as false positives or negatives.
