The initial nucleic acid test was negative, whereas at this time characteristic lung changes appeared, by repeated nucleic acid tests, it was positive, as a result, a considerable number of early patients have been missed. If with the positivity of initial nucleic acid acts as the gold standard, the sensitivity of characteristic lung CT changes will be only 12 %, which will cause huge interference or even misleading to clinical work; as a result, diagnosis and treatment will be delayed, and even the potential patient will not be isolated in time, thereby causing the spread of the virus. In conclusion, there is poor consistency between the positive rate of initial nucleic acid test and the changes of lung CT in patients with COVID-19, and initial nucleic acid test exhibits low sensitivity. ./cache/cord-265760-ch4pcy21.txt ./txt/cord-265760-ch4pcy21.txt
