So far, only two companies have received emergency authorization from the FDA for coronavirus antigen tests. One is Quidel, which is, according to a representative, producing millions of tests each month, many of which have been distributed to urgent care centers and medical clinics in the United States. On Monday, a second firm, Becton Dickinson & Co., also entered the fray with a point-of-care antigen test that can reportedly produce results in 15 minutes. While speedy, both Quidels and BDs tests may produce false negatives between 15% and 20% of the time. Other antigen tests have made headway overseas, and experts estimated that several more will likely seek clearance in the U.S. in coming months.
