These proteins include multiple epitopes. Using the principle of specific binding of antigens and antibodies, the presence of antigens can be detected by antibodies to directly Prove that the sample contains the new coronavirus. The applicable sample types for antigen detection reagents are generally samples from infected sites, such as throat swabs. The antibodies detected are mainly divided into two types: IgM and IgG. At present, there is no systematic research on the production and duration of these two types of antibodies against the new coronavirus. Under normal circumstances, IgM antibodies are produced early. Once infected, they are produced quickly, maintained for a short time, and disappear quickly. A positive blood test can be used as an indicator of early infection. IgG antibody is produced late, lasts for a long time, and disappears slowly. A positive test in the blood can be used as an indicator of infection and past infection.
