The invention discloses an immunochromatography kit for jointly detecting IgM (Immunoglobulin M) and IgG (Immunoglobulin G) of multiple pathogens, the kit comprises an upper cover and a base which are clamped with each other, a sample groove is formed in the middle of the base, a plurality of test paper clamping grooves are formed along the radial direction of the sample groove, and the test paper clamping grooves are respectively communicated with the sample groove through a guide groove; a sample adding hole and an observation window are formed in the positions, corresponding to the sample groove and the test paper clamping groove, of the upper cover respectively, a test strip is clamped in each test paper clamping groove, each test strip is used for detecting one TORCH pathogen to be detected, and each test strip comprises a bottom lining. A sample pad, a first marker combination pad, a second marker combination pad, a reaction film and a water absorption pad which are tightly connected are sequentially attached to the upper portion of the bottom lining from front to back, the reaction film is sequentially coated with a first detection line, a second detection line and a quality control line from front to back, the first detection line is coated with a mouse anti-human IgG antibody, and the second detection line is coated with a mouse anti-human IgM antibody. According to the kit, multiple pathogens can be detected at the same time only through one-time sample adding, and co-detection of the IgM antibody and the IgG antibody is achieved.
