Can a new coronavirus antigen test detect influenza A?

　　"COVID-19 antigen" refers to the antigen test for the novel coronavirus, while "influenza A" refers to type A influenza. Under normal circumstances, the antigen test for the novel coronavirus cannot detect type A influenza. If you have concerns, it is recommended to consult a physician. Detailed explanation is as follows:

　　The novel coronavirus antigen test is a specific in vitro diagnostic reagent used to detect whether a person is infected with the novel coronavirus. It works based on the principle of specific binding between antigen and antibody, whereby antibodies recognize antigens of the novel coronavirus and allow their detection. However, type A influenza is an acute respiratory infectious disease caused by the type A influenza virus. There are differences between type A influenza virus and the novel coronavirus in terms of viral type, structure, and transmission methods. Therefore, the novel coronavirus antigen test cannot effectively detect type A influenza.

　　Although type A influenza and novel coronavirus infection have similar symptoms, they are caused by different pathogens and therefore require different testing methods. Testing for type A influenza typically involves specific detection methods targeting the type A influenza virus, such as virus isolation and culture, nucleic acid testing, or serological testing.

　　To prevent both novel coronavirus infection and type A influenza, it is important to maintain personal hygiene, wash hands frequently, wear masks, ensure adequate ventilation, and avoid crowded places as much as possible.
