While there is no stock-specific news for Quidel today, the company's stock might be hurt by news that Abbott Laboratories (ABT) has received an Emergency Use Authorization from the U.S. Food and Drug Administration for a COVID-19 portable antigen test that will deliver results within 15 minutes. The test, BinaxNOW COVID-19 Ag Card, will be priced at $5.
