Cue Health, the once high-flying San [Diego] biotech supplying rapid COVID-19 test kits to the NBA and others, is shutting down this week.

Cue’s closure comes a week after the U.S. Food and Drug Administration warned consumers to throw out any of its COVID-19 test kits because they could give false results. The San Diego firm said it has stopped selling the COVID-19 tests, which was its only fully FDA-approved commercial product.
