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

When an epidemic occurs in a place, in order to accurately detect the pathogen, find the infected person as soon as possible and cut off the transmission chain of the virus, it is generally necessary to carry out multiple rounds of testing in time. Judging from the implementation of full-time nucleic acid testing in many cities in China, it is particularly effective and necessary to take multiple rounds of full-time nucleic acid testing in time and quickly for epidemic prevention and control. There are many things to pay attention to before, during and after nucleic acid detection. We should cooperate with the arrangement of medical staff. Let's take a look at the precautions!

First, before nucleic acid detection:

1. Don't eat or drink for two hours before the test. Sensitive person in pharynx should not eat to avoid vomiting.

Don't smoke, drink, chew gum, etc. Half an hour before sampling, so as not to disturb the test results.

3. Keep your distance when waiting in line. People with a medical history should explain the situation to the medical staff as soon as possible. Shen obeyed the arrangement of the field staff, kept the distance of 1 m, and cooperated with the staff to complete the information registration.

Second, during sampling:

1, for nucleic acid detection, you must pay attention to personal protection and wear masks, because some people who are tested at the same time may have nausea, vomiting or cough because they are sensitive to throat swabs, which will pollute the surrounding environment. In order to reduce exposure and cross-infection, subjects should take off their masks after medical staff prepare throat swabs, especially in closed collection places.

2. The bar codes of ID cards and grades should be wiped clean with 75% alcohol. You'd better wear disposable gloves.

3. Try to sit up straight, chin slightly raised, mouth wide open and make an "ah" sound when sampling. It is normal to have a slight nausea reflex. Hold your head back and open your mouth. If it is sour and refreshing, cover it cleverly.

4. In the process of sampling, the sampled person must cooperate with the sampling personnel as much as possible, and must relax to avoid scratching the mucosa with the sampling swab. Sampling with oropharyngeal swab and nasopharyngeal swab will make the sampled person feel slightly uncomfortable. If you have a sore throat or itchy nose, if you want to retch, cough, sneeze, etc. You must cover your mouth and nose with a tissue or elbow immediately and don't point at others.

5. Don't touch the inspection table and other items during specimen collection, and don't put personal items on the sampling table.

After sampling

Third, after sampling:

1, according to their own situation, add warm water.

2. If there is slight discomfort or bleeding in the pharynx, you can drink water later, do not drink overheated water, and eat immediately.

3. Leave the collection point as soon as possible after sampling, and don't stay at the scene.

In the eyes of ordinary people, nucleic acid testing seems to have only two steps: registering for sampling and waiting for a few hours to check the results on the health code. In fact, behind the seemingly easy two steps, there is a gene amplification laboratory (PCR laboratory) and so on, and a lot of work is done by inspectors. The birth of a nucleic acid report needs to go through many procedures, such as sampling, specimen delivery, specimen signature, nucleic acid extraction, nucleic acid transfer, nucleic acid amplification and result review. Therefore, ... we must respect our nucleic acid testing, and do a good job in nucleic acid testing, as well as the precautions before, during and after nucleic acid testing.
