Coronavirus disease 2019 (COVID-19) broke out in Wuhan, Hubei, China in December 2019. Tens thousands of people have been infected with the disease. Our aim was to distinguish severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients from SARS-CoV-2-negative patients. ⋯ There were 38.5% of control patients had higher procalcitonin (PCT) levels than 0.5 ng/mL, which was significantly higher than that percentage of COVID-19 patients (X2 = 22.636; P < .05), and COVID-19 patients were also more likely to have decreased or normal urea and creatinine levels than control patients (X2 = 24.930, 8.480; P < .05). Younger age, exposure to Wuhan, fever, cough, and slight changes in routine blood workup parameters, urea and creatinine were important features discriminating COVID-19 from control patients. Slightly increased, but far less than 0.5 ng/mL, PCT levels also differentiated COVID-19 patients from control patients.
