COVID-19 nucleic acid detection is of great significance for scientific and accurate prevention and control. Large-scale nucleic acid detection can accurately and timely find the infected people in COVID-19, reduce the risk of transmission and protect the susceptible population. It will play a very important role in resolutely preventing the epidemic. There are five "essentials" in queuing for nucleic acid testing: arrive on time, register information accurately, wait in line orderly, wear a mask all the time, and leave quickly after testing.
Individuals should pay attention to 1 when conducting nucleic acid detection, and don't eat: to avoid vomiting during sampling, don't eat 2 hours before sampling. 2, relax, swallow less: in order to reduce the occurrence of severe cough reaction, keep relaxed when sampling, don't be nervous, reduce swallowing and clear throat.
