What should I pay attention to when doing nucleic acid testing?

At present, the situation of epidemic prevention and control in COVID-19 is very severe, and nucleic acid detection is an indispensable and effective proof. All parts of the country also put forward specific requirements for nucleic acid testing certificate, from effective nucleic acid testing certificate within 7 days to 48 hours, and now to 24 hours. Let's take a look at what we need to pay attention to before doing nucleic acid testing.

1, get your mobile phone and ID card. If you don't have an ID card, you need to provide your ID number, or you can prepare your own sampling code in advance.

2. Try not to eat 2 hours before sampling to avoid vomiting. At present, the detection of nucleic acid is mainly based on throat swab. When sampling, some people will feel sick or uncomfortable because they have to put the reagent in their throat. So try not to eat 2 hours before sampling to prevent vomiting and nausea.

3. Do not smoke, drink, drink water or chew gum within 30 minutes before sampling, so as to reduce the interference on throat swab sampling and the influence on test results.

4. Testers need to wear masks correctly, take off masks before testing, and keep a distance of more than one meter from others. It is inevitable to wait in line in the process of nucleic acid detection. Remember to wear a mask correctly during this process, because sometimes taking it lightly will lead to such contact risks. When waiting in line, there will inevitably be some unknown infections, so be vigilant, wear a mask and keep a good distance from others. Don't walk around the sampling site at will to prevent cross infection.

5. Wear it immediately after testing, and you can prepare a spare mask, which is convenient to replace at any time after pollution. The mask is removed during the test, but it must be worn in time after the test is completed. I felt fine when I didn't finish eating, and I forgot to bring my mask.

6, sampling, should try to sit up straight, chin slightly up, open your mouth, a continuous "ah" sound. It only takes a nurse ten seconds to finish. You can add more water after sampling, and generally there will be no discomfort.

7, after the completion of sampling, must obey the unified command of the field staff, in accordance with the provisions of the path to leave the sampling point as soon as possible to return home. Try not to take taxis, buses, subways and other public transport to avoid cross-infection.

The epidemic situation is repeated, and every time the epidemic situation rages, all nucleic acids are inevitable. So what is the significance of nucleic acid detection?

COVID-19-specific gene fragments in infected people can be found by nucleic acid detection. If it is positive, it means that the patient is infected. The most important function of large-scale nucleic acid detection is to screen asymptomatic infected people. When symptoms appear, everyone will be vigilant, treat and isolate themselves to reduce the risk of transmission. But when there are no symptoms, the awareness of protection may not be so high, which will bring greater risks to normal people. Therefore, nucleic acid detection can help us screen out infected people and isolate and block them as soon as possible.
