What are the advantages of antigen detection over the "gold standard" of nucleic acid detection?

Compared with nucleic acid testing? Gold standard? What are the advantages of antigen testing? The advantages of antigen detection are: firstly, it can reduce the discomfort caused by physical examination, reduce the rude behavior of medical staff, reduce many contradictions between doctors and patients, reduce the burden for medical staff, and prevent the risk of cross-infection and aggregation infection. Moreover, it is very convenient for your own use, and it is also convenient for people who travel frequently. I still have the following views on this:

1. What is antigen testing?

Antigen test is a newly released nucleic acid test paper, which can effectively detect whether the body is infected with COVID-19, which really brings too much convenience to people, and also reduces the incidence of infection without going to hospitals and test sites. During the epidemic, we advocated not gathering and doing a good job of protection, and we achieved a high degree of unity. It can be seen that China is a powerful country, which is developing at a speed that can be seen by our naked eyes.

Second, how to carry out antigen testing? What are the procedures for antigen testing?

Before self-test, you need to wash your hands, then open the test paper box and read the instructions carefully to check the situation of self-test paper, including cotton swabs, sampling tubes and test cards. Next, we need to make sure that the test environment generally requires room temperature 14 to 30 degrees Celsius. We took out the test card and laid it flat in a clean place. Blow the nose clean with paper before sampling, then take out the nasal swab, and be careful not to touch the head of the swab with your hand. Then slightly raise your head, put the cotton swab into the nasal cavity, and rotate 1 ~ 1.5cm near the nasal cavity for at least 5 times, so that the two nasal cavities are synchronized. After the collection, put the successfully collected nasal swab into the sampling tube for full contact, cover the sampling tube and drop the liquid into the test card, and wait for the result.

Third, the epidemic is now imminent.

Everyone knows the seriousness of the epidemic. The country has tried its best to protect our health, and we can't give the country any trouble. Now, a serious epidemic has spread in many places. Please remember not to enter or leave crowded places before you are completely cured!
