The nucleic acid test for novel coronavirus pneumonia is performed within 6-24 hours. The nucleic acid test for novel coronavirus is performed using the polymerase chain reaction, or PCR. The current clinical requirement is for results to be available within six hours for fever outpatient nucleic acid testing and within 24 hours for outpatient or inpatient collections. In terms of testing, the entire experimental response time is generally more than three hours from the time the laboratory enters the testing process until the results are available. In addition, there are test preparation time, specimen collection time, etc., so the fastest general requirement within six hours to produce results. In addition, we also need to take into account the different hospitals, test personnel allocation and other circumstances to consider.
