Because of a sudden rise of COVID-19 cases in several Chinese cities, the country is making five COVID-19 antigen test kits (抗原检测试剂盒) available for self-testing, All made by local companies, the kits can be bought in stores and online.

Antigen tests are used to test for COVID-19. But they work differently from the nucleic acid tests (核酸检测) that we are all familiar with. “Antigen is like the ‘clothes’ of the virus, while nucleic acid is the gene (基因) of the virus,” said Zhang Wenhong, head of the infectious disease department (感染科) at Fudan University’s Huashan Hospital.

The antigen tests are beneficial because they produce results faster, in around 15 minutes, and don’t require a lab. People can use them in their own homes at their convenience.

But they aren’t as accurate . “In the early stage of infection, the amount of virus can be very low,” Zhang said. “The nucleic acid test can detect it but an antigen test cannot.”

According to the National Health Commission, three categories of people will be able to take an antigen test. They are people who have had a fever or respiratory symptoms (呼吸道症状) within five days, people undergoing centralized or home isolation (隔离), and other people who just want to take a test.

People who test positive with the antigen kits will be treated as COVID-19 cases and must contact local

authorities immediately, said the State Council. They will need to undergo centralized quarantine (隔离) and have regular nucleic acid tests, reported China Daily.

At this time, China is sticking to its zero-COVID policy. With the Omicron variant producing more asymptomatic (无症状的) cases, it is hoped that the introduction of antigen tests will help authorities to find infected people more rapidly, said Zhang.
