As coronavirus cases surge in hard-hit Florida, so do the turnaround times for test results. The reasons are many: Often it has to do with lab staffing, backlog, or equipment shortages. Some tests are done in house, while others are sent to overloaded labs out of state. Health experts say test results that come back after two or three days are nearly worthless, because by then the window for tracing the person’s contacts to prevent additional infections has essentially closed. But there is one place in Central Florida where a group of people are being tested and getting results within a day: the NBA.
