A nasopharyngeal SARS-CoV-2 PCR was obtained on day 1 of his admission and was negative. This case highlights multiple negative nasopharyngeal SARS-CoV-2 PCR swabs in a patient with high clinical suspicion for SARS-CoV-2, who ultimately tested positive when deep sputum was sent for PCR nine days into his admission (10 days after respiratory symptoms started). Therefore, to improve the odds of making a definitive diagnosis, additional testing methods such as sputum for PCR and serology testing should be considered in patients with a high clinical suspicion of COVID-19 who have a negative nasopharyngeal PCR. Subsequently [7] , conducted a study on 127 patients in Beijing Ditan Hospital comparing RT-PCR versus droplet digital PCR (ddPCR) testing, which is reported as being more sensitive in virus detection, in addition to assessing viral load with disease progression.	./cache/cord-310946-rjwyirld.txt	./txt/cord-310946-rjwyirld.txt
