What to do before the swab test？
Why implement full coverage of DNA swab testing?
What should be paid attention to in DNA testing?
The latest statistics on the COVID-19 released by Johns Hopkins University in the United States on the 9th show that the cumulative number of confirmed cases in the United States has exceeded 60 million.
Nucleic acid detection is an effective method for precise prevention and control.
After the COVID infects the human body, it will multiply in the respiratory system.
Using a nasopharyngeal swab to detect sputum can determine whether the human body is infected with the virus, and can quickly and accurately “find out” the virus.
The recent spread of the epidemic has brought new pressure to epidemic prevention and control around the world. There are even reports of a country’s leader being positive for the new crown. Mexican president tests positive for coronavirus. The President of Paraguay has tested positive for the new crown. Poland: President tests positive for coronavirus. Brazil’s president tests positive for coronavirus. etc.
On the basis of continuing to perform nucleic acid testing on key groups of people, close contacts, etc., to identify the infection chain as soon as possible, block the transmission route, control the spread of the epidemic, and implement large-scale full nucleic acid testing, we must achieve early detection, early reporting, Early isolation, early treatment, active search for potential new coronavirus infections, and targeted prevention and control measures are also adopted to protect the health of the masses, ensure the rational flow of the population, and maintain the stable development of social and economic life order. It is very important. significance.
What methods are available for COVID swab testing?
Nucleic acid detection generally adopts the nasopharyngeal swab detection method, including nasopharyngeal swab detection and oropharyngeal swab detection.
At present, most hospitals and institutions in our city use oropharyngeal swabs.
This method is the least painful and more convenient to collect samples.
Is it painful to take a throat swab?
A throat swab is a method of collecting a specimen from the throat area, it is painless, mild nausea or sore throat method, which can be relieved or disappear quickly after collection.
Are DNA tests dangerous to humans?
There is no harm to the human body, only when the throat swab is collected, a slight foreign body sensation will be felt when the cotton swab enters the throat.
What should I pay attention to before and after the inspection?
Before detection
Before the nucleic acid test, it is best not to eat for 2 hours, otherwise, it will cause vomiting.
Do not drink water, smoke, drink, or chew gum 30 minutes before sampling.
Before the examination, reduce the number of swallowing movements, and do not do throat-clearing movements, such as expectoration and spitting.
For example: before the nasopharyngeal swab collection, the subject should provide the collector with the relevant past medical history or related matters.
Such as history of nasal surgery, nasal septum, blood disease, throat disease, or taking anticoagulant drugs.
Be sure to wear a mask before going to the test, take out the mask before the test, and put it on immediately after the test. You can prepare a spare mask, which can be replaced at any time after pollution.
Checking
When collecting oropharyngeal swabs, the subject should tilt his head back, relax as much as possible, take a deep breath, and open his mouth to make an “ah” sound, which will help reveal the throat, but symptoms such as irritating dry cough, nausea and vomiting may occur during this process.
Nasopharyngeal swab During the process of nasopharyngeal swab, symptoms such as swelling, itching, and sneezing may occur, which can be covered with a tissue or elbow.
After detection
Leave the collection site immediately after collection to avoid spitting and vomiting near the collection site.
You must pay attention to hand hygiene before and after the nucleic acid test.
You can wipe your hands with your hands, or you can use hand sanitiser, disposable alcohol, and disinfectant cotton pads.
Important reminder:
●Be careful to wear a mask, do not expose your nose and nose, do not take it off at will, or pull the mask to your chin.
●There should be an orderly queue, keep a distance of 1 meter, do not get together, do not gather.
●When waiting in line for a long time, pay attention to sun protection, sun protection, scientific hydration, and a reasonable diet.
● Try to avoid taking public transportation to the nucleic acid test sampling site.
The current situation of epidemic prevention and control is very complicated.
Every day, take care to protect your body.
Wear a mask and follow the epidemic prevention regulations.
Protect yourself and protect others at the same time.
New coronavirus pneumonia cases.
Please accept the general guidelines for prevention and control.
Daily Travel Prevention Control Guidelines.
Take the bus, take the subway.
To minimise contact, payment can be made using a transport card or a mobile app.
Avoid touching public facilities such as seats, armrests, car doors, and armrests with your hands as little as possible. If you do, do not touch your mouth, eyes, and nose directly with your hands, and disinfect your hands in time to avoid contact infection.
Hospitals and other places, after returning home, you should disinfect your outerwear.
