A new study reveals that more than 40 percent of positive results in rapid antigen tests were false, raising concerns as provinces increasingly rely on the rapid tests in forming COVID-19 response strategies. The study, conducted by the University of Toronto’s Rotman School of Management, was published in the JAMA peer-reviewed journal on Jan. 7, 2022.
