Is antigen testing really inaccurate? How can I determine yang more quickly when symptoms appear?

The accuracy of antigen detection is affected by many factors, including sample collection, detection method and detection opportunity. Studies have shown that the accuracy of antigen detection may be slightly lower than that of nucleic acid detection. Therefore, if you are undergoing antigen testing or have suspected symptoms, you'd better choose other more accurate testing methods, such as nucleic acid testing.

If there are suspected symptoms, it is recommended to do nucleic acid testing in time to confirm the diagnosis. While waiting for the test results, you need to keep good personal hygiene habits, try to avoid contact with others and prevent the spread of the virus. If the test result is positive, isolation treatment should be carried out in time, and relevant measures should be taken according to the requirements of local health departments to prevent the spread and spread of the virus.

In a word, in the prevention and control of epidemic situation in COVID-19, we need to be vigilant and take scientific and effective preventive measures, including wearing masks, washing hands frequently and keeping social distance, so as to reduce the risk of virus transmission.
