Recently, confirmed cases in COVID-19 and asymptomatic infections in COVID-19 have been found in many areas of China, and many people need nucleic acid testing.
Nucleic acid detection plays a very important role in quickly finding virus-infected people, effectively cutting off the route of transmission and preventing the spread of the epidemic.
So how to do a good job of nucleic acid testing during the epidemic and what matters need to be paid attention to, this issue of Life Edition will give you a detailed answer.
What preparations should be made before nucleic acid detection?
1. According to the notice of the relevant departments, bring my ID card to the nucleic acid sampling point for nucleic acid detection within the specified time.
2. To avoid vomiting during sampling, please do not eat within 2 hours before sampling. To avoid affecting the test results, do not smoke, drink or chew gum for 30 minutes before sampling.
3. In order to avoid cross-infection, wear a mask regularly before and after sampling, do not expose your mouth and nose, do not take it off at will, or pull the mask to your chin; Keep a distance of one meter when queuing, and don't get together or gather.
4. In order to improve the sampling efficiency, please prepare the health code in advance, and according to the arrangement of the field staff, take the initiative to show the health code and enter the information in turn. Old people or children without health codes can register with their ID cards or household registration books.
5. When sampling, please try to keep the distance between your body and the sampler. Don't put anything with you on the sampling table, and don't touch the sampling with your hands. Leave the collection point immediately after collection to avoid spitting and vomiting around the collection point.
6. When collecting throat swab, take off the mask, fold it into a plastic bag or pocket, try to relax, lean back, take a deep breath, open your mouth and make an "ah" sound. In the process of collecting throat swab, throat discomfort may occur. When you want to cough, sneeze or vomit, remember not to face the medical staff or other people, but to face the ground or prepare paper towels. Avoid covering or turning your head by hand during the collection process, and actively cooperate with the sampling personnel to collect samples quickly and accurately.
7. Pay attention to hand hygiene after sampling. If possible, wipe your hands with disposable alcohol, put on a spare mask, put the discarded mask into a designated medical garbage bag, and leave immediately. Don't stay at the sampling point.
8. If the COVID-19 vaccine is inoculated on the same day, the nucleic acid test can only be carried out after 24 hours.
Recently, the climate is cold. When doing nucleic acid testing, we should take measures to prevent cold and keep warm in advance, prepare rain gear, and replenish water, salt and minerals while waiting for sampling.
Other matters needing attention in nucleic acid detection
1. The person in front has just finished measuring, so the tester in the back should not sit on it in a hurry, let alone take off the mask immediately, and keep a safe distance. The doctor will pack the last measurement, disinfect his hands and take out a new cotton swab, so he should quickly go forward and sit down.
2. When the doctor reaches over the cotton swab, he quickly takes off the mask, opens his mouth wide, holds his breath, and puts on the mask immediately after cooperating with the doctor in sampling.
Don't wear a mask after the exam. Never spit in the trash can next to you. Many people will inevitably lead to the growth of bacteria and the potential spread of viruses. In fact, medical cotton swabs are clean and sterile, and saliva produced after testing is normal and can be swallowed directly.
4. The number of pharyngeal viruses will be affected by diet and swallowing. So don't eat saturated drinking water 1 hour before the test. Moreover, if you are stimulated during the test, causing cough, nausea and vomiting, then eating too much may lead to aspiration.
5. Some people have symptoms of upper respiratory tract infection before testing, so they generally choose to test the parts with lighter lesions and do a good job of follow-up. If there is nasopharyngeal hemorrhage or severe edema, the detection should be suspended.
6. Bring an extra mask. Prevent pollution after taking off and putting on, and at the same time prevent the protective ability of the mask from decreasing due to sweating when waiting in line for a long time.
7. Don't be hungry, tired or stay up late before the exam. Tests are often queued, and excessive hunger may lead to hypoglycemia or fainting.
8. In addition, intense post-exercise fatigue, intense mood swings, staying up all night, etc. may all cause unstable factors in the detection process. Keep a calm mind, get enough sleep and eat reasonably.
Why can't I smoke 30 minutes before nucleic acid testing?
The factors affecting the results of nucleic acid detection in COVID-19 are very complicated. Smoking is not allowed before nucleic acid detection, so as to avoid harmful substances in tobacco from affecting the oral or nasal environment and destroying the activity of epidermal cells. Especially smoking half an hour before the exam, repeated blowing and puffing may lead to a significant decrease in viral load.
If the smoker's throat secretion increases, it may be accompanied by coughing, spitting and other behaviors, which will seriously affect the accuracy of the test results and may lead to false negative.
