- In a population of patients with a low prevalence of SARS-CoV-2 infection, repeat testing of negative patients who had persistent symptoms still yielded a negative result in 96% of the cases. Out of more than 5,000 patients who were tested, 4% of patients were tested more than once, and 96% of those patients were tested twice. The largest proportion of these patients (71%) were those who had an initial negative test followed by a repeat test done for persistent symptoms.
