One‐step and sequential SARSCOV‐2 polymerase chain reaction tests would not work every time

Abstract

Among 68 patients with initial negative test results, 33.8% of patients had subsequent positive PCR test results for second time and 17.4% of the patients who performed third PCR test had positive result. Performing serial RT-PCR tests could not significantly increase the detection capability of SARS-COV-2 after initial negative test results. Repeated RT-PCR tests in short time intervals for patients with initial negative results also remained negative.
