Nucleic acid detection of novel coronavirus infections takes at least 6 hours to produce results because many steps are required to detect the RNA structure of viral nucleic acids, and laboratories mainly use PCR amplification for extraction and culture and then analysis of the results. This detection method is highly sensitive, but requires high laboratory conditions, high cost, and completely manual operation, making it a tremendous workload. The test is performed mainly by sampling nasopharyngeal swabs, sputum, and lower respiratory secretions. This method of nucleic acid testing can determine whether a patient has a novel coronavirus infection, and if so, early detection and treatment can be provided.
