Can antigens detect influenza A?
Disease description:
I have been feeling unwell recently and am worried that I might have contracted influenza A. I heard that antigen testing is a quick way to detect viral infections, but I'm not sure if it can accurately detect influenza A. Can antigen testing be used to detect the influenza A virus? How accurate is it?

Influenza A refers to type A influenza. Generally, antigens can detect type A influenza.
Type A influenza virus has certain specific protein structures on its surface; these proteins possess unique antigenicity. Influenza A antigen detection kits contain antibodies specifically designed to recognize these viral antigens, typically monoclonal or polyclonal antibodies that have been specially developed and prepared. When the influenza A viral antigens in the sample meet the antibodies in the detection reagent, a specific antigen-antibody binding reaction occurs. This highly specific binding forms the basis for antigen tests to identify the influenza A virus.
In addition to specific antibodies, antigen detection reagents also contain substances or systems capable of generating detectable signals. When antigens bind to antibodies, a series of chemical reactions or physical changes are triggered, amplifying and displaying the detection signal, thus enabling rapid detection of the influenza A virus.
Maintaining good personal hygiene habits in daily life, such as washing hands frequently and wearing masks, can help prevent the spread of diseases.
