Repeated antigen testing of 12 SARS-CoV-2-positive nursing home residents using Abbott BinaxNOW™ identified 9/9 (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 was reliable in residents with evidence of early infection.
