Yesterday, it was brushed by Shanghai friends doing the new crown antigen self-test weibo and circle of friends. Funny and sour, come and feel it:
- So what, officially, there is no second child.
No, it shouldn't... No, it won't... Can't be so unlucky... Luckily, thankfully!
How similar is this mental activity to pregnancy testing!
- In the past, two bars would have more lives, and now two bars may have fewer lives. In the past, two bars others would congratulate you, and now two bars, others will stay away from you.
- Fellow males, don't miss the opportunity
- From top to bottom from old to young, one can not be less, poke more safe.
- The children were very happy and thought they were digging their noses.
- The dog did not survive, and the stabbing became like this.
It is said that 25 million people in Shanghai poked themselves in their nostrils at home that day, setting a Guinness record for the largest number of people poking their nostrils themselves on the same day.
This wave of suffering is also a mixture of sympathy and laughter.
Beijing has not yet released antigen test kits in the community on a large scale, but they can be purchased in major online stores and pharmacies.
Judging from the news released a few days ago that the new coronavirus antigen testing is temporarily included in medical insurance, and then to the latest version of the national epidemic prevention policy adjustment, the detection mode of "antigen screening and nucleic acid diagnosis" may be a major trend in the future.
I don't know if you are in the area, can you use medical insurance to buy a new crown antigen test kit in designated medical institutions and designated retail pharmacies? Are you already self-testing with an antigen kit?
Then again, while COVID-19 antigen testing is closely related to us, there seems to be a lot of vague content.
For example, what exactly does antigen testing detect? What is the difference between antigen testing and nucleic acid testing? Will antigen testing replace nucleic acid testing? When do I need to do antigen testing?
I went to consult a doctor for everyone, and I will talk about it in the form of Q&A below, if you have more questions or doubts, please leave a message in the message area.
Q: What is the test for COVID-19 antigen?
At present, there are three main methods to detect whether the virus has invaded the human body: nucleic acid detection, antigen detection and antibody detection.
Both nucleic acid detection and antigen detection are methods of direct detection of viruses, but the parts of the virus that are labeled are different. The new coronavirus is composed of an RNA core and a protein shell, and nucleic acid detection is equivalent to detecting the core of the virus, and antigen detection is equivalent to detecting the coat of the virus.
Compared with nucleic acid detection, antigen detection is faster and more convenient to operate. The testing process is like a pregnancy test with a pregnancy test stick, it can be performed by yourself, and the results are immediately desirable.
Two bars are positive and one bar is negative
However, it is less accurate than nucleic acid testing, and there is a possibility of false negatives and false positives.
It is for this reason that although antigen test kits are available in early March, the Health Commission does not recommend that you buy antigen test kits and self-tests.
Q: The results are not accurate, why should antigen detection be used?
Because the current epidemic prevention and control situation is different from before!
Confirmed COVID-19 cases and asymptomatic infections have been increasing across the country this month.
According to the data of the Health Commission, there were more than 4,000 new cases in Shanghai yesterday, and 1,055 new locally confirmed cases in Jilin. This is still happening under the premise of closed control in many areas.
Although Shanghai is now under control, the number of asymptomatic infected people has been growing. By the afternoon, I had more than 2,000 more asymptomatic infections in Shanghai.
Data as of March 29
I have to say that this growth rate does look a little scary.
However, we should also see that although the infection rate of the virus is increasing, the fatality rate and severe disease rate caused by the infection with the virus itself have dropped greatly. Dr. Zhang Wenhong previously posted:
Immune function is normal, vaccinated, no matter what kind of vaccine, as long as it is strengthened, basically fine. Eliminating fear is the first step we must take.
In such a situation, the distribution of the new crown antigen test kit allows everyone to test themselves, can more quickly know whether the tester is infected with the new crown virus, and as early as possible to detect and isolate the infected person.
For example, as in Shanghai, the use of antigen detection, everyone does not have to queue, reducing the risk of infection caused by the gathering of people to test.
Although antigen detection is not perfect, different detection methods are suitable for different scenarios, and there is no completely accurate detection method. In the current situation, antigen detection is a more economical approach as a coarse sieve tool.
Q: Do you have an antigen test, do you still have to do nucleic acids?
See what the purpose of nucleic acid testing is. Currently, antigen-negative replacement of negative nucleic acids as travel credentials is not supported.
The Health Commission said that positive antigen is not used as the basis for confirming the diagnosis of the new crown, and a positive nucleic acid test is still the basis for the diagnosis of the new crown virus infection.
In the shanghai full staff poke the nose, in fact, there are many positive results found. Medical staff conduct nucleic acid testing for positive personnel for the first time, early detection and early control, which helps to control the epidemic situation. At the same time, it also saves a lot of medical resources and uses these resources where they are more needed.
This is the so-called "antigen supplementation, nucleic acid confirmed" monitoring model.
Q: Who can do antigen testing?
If you have a large cluster of infections in your area.
If you are an isolated observer.
Or you don't belong, but you have symptoms of fever or respiratory infection, you can get tested for COVID-19 antigen first.
If the test is positive, be sure to contact the community or hospital for a nucleic acid test as soon as possible.
If the test result is negative, but you have symptoms similar to the new crown infection, go to a medical institution as soon as possible for nucleic acid testing; if it is inconvenient, you should self-isolate at home, avoid going out, and conduct an antigen self-test once a day for 5 consecutive days.
The contagiousness of the new generation of the new coronavirus is now not the same as when the first outbreak of the epidemic was launched.
The rate of infection is many, many times higher, and the number of asymptomatic infected people will certainly increase.
Data source: Phoenix Network Technology Channel reported that "daily infection exceeded three thousand! How strong is the spread of Omicron?"
If you accidentally become a close connection, a sub-close connection or you have symptoms such as fever, sore throat, nasal congestion, dry cough, fatigue, etc., the new crown antigen self-test can at least be detected as soon as possible, which is also a protection for your family and the people around you.
The use of the method everyone must also pay attention to.
At present, antigen detection kits can be purchased in major online stores and many pharmacies in Beijing. I purchased a copy of the COVID-19 Antigen Kit:
It looks like this
There's that in there
I found a more professional operation video released by CCTV, for your reference:
I followed the operation again, and the main points of operation were summarized as follows:
Wash and wash your hands.
Two turns, a cotton swab inserted into the nasal cavity 1-1.5 cm, close to the nasal cavity rotation 5 times.
Insert the sampled swab head into the preservation solution, spin for at least 30 sec, press the swab head at least 5 times, and stand still for 1 min.
Four drops, the collected solution drops into the test card wells, 4 drops.
Five looks, observe and wait for the results.
Note that two bars indicate positive, one bar indicates negative, if the C area is not displayed, it means that the test failed, is an invalid test.
The operation process of the new crown self-test products of different manufacturers may be different, and the specific product description shall prevail.
It feels very sour after doing it, but it is still easy to operate, have you learned (waste)?
Pay attention to the detection of garbage after the test, be sure to properly dispose of the test garbage, do not cause pollution to the environment.
Ordinary people, if the test result is negative, put the contents of the kit in a sealed bag, which can be treated as general garbage. If the test result is positive, the sealed bag is handed over to the transporting medical staff. Medical staff will follow the relevant procedures.
Isolation observers, regardless of the test results, all used items should be packed in sealed bags and treated by medical staff at the isolation point.
