Several studies have suggested that the number of unique patient specimens tested for SARS-CoV-2 is directly related to the positive identification of the virus and that there may be a high false-negative rate of molecular testing. 2, 3 The study by Zhang et al reported 41 hospitalized patients with an initial negative PCR test who had at least one positive result on subsequent testing. 4 We agree that there may be a role for repeat testing in patients with high clinical suspicion of Low Utility of Repeat Real-Time PCR Testing for SARS-CoV-2 in Clinical Specimens Distinct characteristics of COVID-19 patients with initial rRT-PCRpositive and rRT-PCR-negative results for SARS-CoV-2	./cache/cord-322724-7l1668bf.txt	./txt/cord-322724-7l1668bf.txt
