Title: Low Utility of Repeat Real-Time PCR Testing for SARS-CoV-2 in Clinical Specimens Cord-id: urwn7bsu Document date: 2020_7_4
ID: urwn7bsu
Snippet: Abstract: In a multicenter cohort of 22,315 patients tested for COVID-19, 1676 (7.5%) had repeat testing via real-time PCR following an initial negative test. Of those retested within seven days of their first negative test, only 2.0% had a positive result. This suggests that repeat testing from the same source is unlikely to provide additional information.
