RE:RE:taking time to do it right This is an antigen test so the goal is to identify persons infected but not yet symptomatic. Not really just people who are asymptomatic and infected.. as some don't get that ill, but also those who are ABOUT TO BE VERY symptomatic and are harboring the virus yet have no idea. If Toronto Maple Leafs had this test before Auston Matthews went for practice they could have excluded the carrier who didn't know he already had the virus and no infection would have happened. I would presume they used a Covid antibody test before putting these players together and that would be negative as he hadn't yet gotten ill. You must get a good immune response (ie be fairly ill) in order for the Antibody to be produced and then test positive on the current test. The antigen test is a huge step forward, Fingers Crossed
