Novel Coronavirus Nucleic Acid Test laboratory tests usually take 4 to 8 hours to produce results. Nucleic acid testing is currently the gold standard for diagnosis of novel coronaviruses and plays a critical role in the control of novel coronaviruses. Although the collection of a throat swab in nucleic acid testing usually takes only 5 minutes, the collection of the specimen requires a number of steps such as storage, transportation, pre-test decontamination, laboratory testing, and return of the results. If a suspected positive specimen is encountered, retesting and confirmation by a higher-level laboratory are also required. 4 to 8 hours is generally the time interval for novel coronavirus nucleic acid testing in most hospitals. The collection of nucleic acid specimens requires the close cooperation of the person being collected and following instructions in order to collect high-quality specimens quickly and expeditiously. People with negative nucleic acid test should not be careless, but should do their daily protection, wear a good mask when going out, and try to avoid taking crowded transportation. Personal hygiene should be practiced to reduce the risk of novel coronavirus infection.
