Antibody Test Could Show Who Has Immunity From Coronavirus Within Minutes

It would be used to detect past infections of people who may not have known they were sick and are now healthy. News4 spoke to former FDA commissioner Dr. Margaret Hamburg. Doreen Gentzler reports she said tests like this are an important step forward.
