How to test the new crown virus at home?Henan Disease Control experts teach you is like using a pregnancy test stick to be pregnant. In the future, if you want to know if you have infected the new crown virus, you can also test it at home.

On March 11, the official website of the National Health Commission issued the "Notice on Printing and Distributing the Release of New Crown Virus Antigen Detection Application Scheme (Trial)" (referred to as "Notice"), which expressed its decision to increase antigen detection as a supplement on the basis of nucleic acid detection and organize formulation to formulate formulationThe "New Crown Virus Antigen Detection Application Scheme (Trial)" ("Trial Plan").

What is antigen detection?What is the difference between antigen detection and nucleic acid detection?Who can perform antigen detection?How to test it at home?The column of Henan Disease Control "Healthy Monthly" interviewed Xu Yuling, deputy chief physician of the Infectious Disease Prevention and Control Institute of Henan Provincial Disease Control and Prevention Center.

What is antigen detection?

Xu Yuling said that antigen detection is a way to quickly detect the new crown antigen. It is to mark the polyxon antibody of the new coronary virus protein on the trial note to detect the new coronary virus antigen in the sample.

What are the differences from nucleic acid detection?

Xu Yuling introduced that there are two advantages of antigen detection compared with nucleic acid detection:

The first is convenient. The fast antigen detection kit is a bit similar to the pregnancy measurement stick. It can be done at home. There is no need to rely on complex instruments and equipment as nucleic acid detection.

The second is fast. Nucleic acid testing is 4 to 6 hours, and antigen detection only takes 10 to 20 minutes to produce results, and it is advisable.

"The antigen detection as a supplementary method can be used for screening for specific people, which is conducive to improving the ability of ‘early discovery’." Xu Yuling said that the antigen detection has always been used in many countries, including Hong Kong in my country.Antigen testing can be carried out in the medical institutions, communities, rural clinics, and even schools at the grassroots level.It is relatively simple. If multiple points of distribution and clustering epidemic occur, those who can discover infections can be discovered faster through antigen detection.

Who can test itself?

According to the "Trial Plan", the antigen detection is mainly applicable to these three types of people:

The first is to go to the grass -roots medical institution for treatment, accompanied by symptoms such as respiratory tract, fever and other symptoms, and symptoms within 5 days.When the primary medical and health institutions are diagnosed, if they have the ability to detect nucleic acid, nucleic acid testing shall be selected; if the nucleic acid detection capacity is not available, antigen detection shall be performed.

The second is to quarantine observer, including home isolation observation, secret and sub -dense connection, entry isolation observation, sealing control areas, and management control areas.

Third, there are community residents with antigen self -testing needs.

How to test it at home?

1. Washing hands and snot.Wash your hands with flowing water or hand disinfection solution.

2. Understand the detection process.Read the antigen self -testing agent supporting manual and antigen self -test -related precautions.

3. Reagent preparation.Check whether the antigen self -test agent is missing or damaged during the shelf life, check whether the nasal swab, sampling tube, and detection card are missing.If the reagent expires or the reagent content is lacking, the test agent should be replaced in time.

4. Sample.When sampling, the nasal swab is inserted into the nasal cavity 1 to 1.5 cm, rotates 4 laps, and then samples another nasal cavity.

5. After removing the swood, push the sampling tube, insert it in, squeeze it with the wall, squeeze and rotate and mix well, and then cover the lid.

6. Drop 4 drops of detection holes and observe the results within 20 minutes. If the T line is brought out, it means that it is positive. If not, the result is negative.If Line C is not out, it means that the quality control line is not released, indicating that the experiment is not established, and repeated operations need to be repeated.(Yao Qingwen intern Hu Yanyi Li Mengshi Li Yunna Shen Chonglin/Video)
