The gold label single card includes a matching cover shell and a bottom plate. The cover shell is sequentially equipped with a sample adding through-hole, a display through-hole, and a breathable hole. The bottom plate is respectively fixed with a nitrocellulose film, a sample adding end water absorbing film, and a water absorbing end water absorbing film. The sample adding end water absorbing film and the water absorbing end water absorbing film are overlapped at both ends of the nitrocellulose film. Above the nitrocellulose film, there are antigen specific detection bands, positive complex judgment bands, and positive complex control bands. From the above structure, it can be seen that the gold labeled single card detected by this utility model can distinguish whether there are virus antibodies in the sample, whether the virus antibody titer in the sample can resist the virus, and whether vaccination is needed by comparing the color depth of the antigen specific detection band with the positive complex control band; By using a blood filtration membrane, the components in the blood are prevented from reacting with the detection card, and the coagulation of the blood is prevented from affecting the detection results.

The gold standard single card for detection includes a matching cover shell (1) and a bottom plate (2). The cover shell (1) is sequentially provided with a sample adding through-hole (3), a display through-hole (4), and a breathable hole. The bottom plate (2) is fixed with a nitrocellulose film (6), a sample adding end water absorbing film (5), and a water absorbing end water absorbing film (7), respectively. The cover shell (1) fixes the nitrocellulose film (6), a sample adding end water absorbing film (5), and a water absorbing end water absorbing film (7). The sample adding end water absorbing film (5) and the water absorbing end water absorbing film (7) overlap at both ends of the nitrocellulose film (6), and their characteristics are as follows Above the nitrocellulose membrane (6), there are antigen specific detection bands (10), positive complex judgment bands (11), and positive complex control bands (12) respectively, and the through-hole (4) is displayed on the nitrocellulose membrane (6) Within the range of, the antigen-specific detection band (10), the positive complex judgment band (11), and the positive complex control band (12) are all within the range of the displayed through-hole (4).
