Nucleic acid testing can also be registered online, that is, go to the hospital that wants to do the testing first, give the information truthfully, and choose the time to make an appointment. After the appointment is successful, a medical staff will call.
It should be noted that don't eat within 2 hours before nucleic acid detection to avoid vomiting, and don't smoke and drink 30 minutes before taking samples, which will affect the test results. Testers should wear masks, keep a distance of more than 1 m from the crowd, and wash their hands immediately after the test.
