Antigen detection generally refers to the detection of 2019-nCoV antigen. The 2019-nCoV Antigen Rapid Test Kit  has been officially launched. Compared with nucleic acid detection, it is more convenient and faster, and is suitable for antigen detection of the whole population. Among them, it is mainly applicable to those who have obvious symptoms and need to be isolated and observed according to relevant requirements. Other groups can also purchase tests by themselves.

1. People with obvious symptoms: If there are obvious symptoms such as dry throat, cough, chest tightness, fever, or even dyspnea within 7 days, they are suspected of being infected with the new coronavirus, and it is recommended to conduct antigen detection to initially confirm whether they are infected with the new coronavirus;

2. Isolation observers: including close and second-close contact with people infected with the new coronavirus, home quarantine, entry quarantine, and personnel in closed and controlled areas, should conduct antigen self-test under the organization and management of relevant management departments;

3. Others: If you feel unwell or have a need for self-testing, you can also perform antigen testing.
