Repeated antigen testing of 12 severe acute respiratory coronavirus virus 2 (SARS-CoV-2)-positive nursing home residents using Abbott BinaxNOW identified 9 of 9 (100%) culture-positive specimens up to 6 days after initial positive test. Antigen positivity lasted 2-24 days. Antigen positivity might last beyond the infectious period, but it was reliable in residents with evidence of early infection.
