What should I pay attention to before and after nucleic acid detection?

1. Under normal circumstances, citizens should not eat two hours before the nucleic acid test. During the collection process, some people will feel sick when the cotton swab touches the tonsils and other parts. If vomiting or splashing occurs, it will pollute the environment; Half an hour before sampling, try not to smoke, drink or chew gum, which may affect epithelial cells and interfere with the results.

2. When sampling, citizens should try to sit up straight, chin slightly raised, mouth wide open, and make a continuous "ah" sound, which can be completed by nurses in just over ten seconds. You can add more water after sampling, and generally there will be no discomfort.

3. It is suggested that people who have not been exposed to new markets and related confirmed or suspected cases should not panic. Especially in the absence of any symptoms at present, don't get together and choose to go to the fever clinic of medical institutions for screening, so as not to increase the risk of infection. Strengthen health monitoring. If you have symptoms such as fever, dry cough, sore throat, diarrhea, and decreased taste, you can go to a medical institution for protection.
