The invention relates to a colloidal gold immunochromatography test strip for simultaneously detecting viral antigens and antibodies. The test strip comprises a first glue strip and a second glue strip which are arranged in parallel, wherein the first glue strip comprises a first sample pad, a first conjugate pad, a first nitrocellulose membrane and first absorbent paper, which are sequentially lapped with one another, the first conjugate pad is coated with colloidal gold marked by the viral antigens, the first nitrocellulose membrane is coated with viral antibodies and antibodies, the viral antibodies are taken as a first detection line, and the antibodies are used for resisting the viral antigens on the colloidal gold and are taken as a quality control line; the second glue strip comprises a second sample pad, a second conjugate pad, a second nitrocellulose membrane and second absorbent paper, which are sequentially lapped with one another, the second conjugate pad is coated with the colloidal gold marked by the viral antigens, the second nitrocellulose membrane is coated with anti-human IgG antibodies and anti-human IgM antibodies, the anti-human IgG antibodies are taken as a second detection line, and the anti-human IgM antibodies are taken as a third detection line. The colloidal gold immunochromatography test strip can be used for simultaneously detecting the viral antigens as well as the IgG antibodies and IgM antibodies of the viral antigens.
