02. About rapid antigen test
Why do we need rapid antigen test?
Antigen refers to a substance that can produce antibodies, it is any substance that can induce an immune response. Antigen testing can be used in the early stage of the disease (after the onset of symptoms within 1-5 days or even during the incubation period) to get positive results. The antigen detection method is more suitable for the time-sensitive investigation of suspected cases of large-scale coronavirus infection and is very effective for areas with concentrated outbreaks.
