The utility model discloses a kit for rapid detection of mycobacterium tuberculosis antibody. The kit comprises a bottom plate (1), a cellulose nitrate membrane (2), a colloidal gold combined pad (3), a sample pad (4) and a water absorption pad (5); and the water absorption pad (5), the cellulose nitrate membrane (2), the colloidal gold combined pad (3) and the sample pad (4) are connected in the horizontal direction in sequence, and are fixed on the bottom plate (1). The kit has the advantages that the water absorption pad, the cellulose nitrate membrane, the colloidal gold combined pad and the sample pad are laid on the bottom plate in sequence, so that the volume is small, and the manufacture is convenient; then the kit is placed in a box body, so that the volume is small and the carrying is convenient; a hole for feeding samples and an observation window for observing results are arranged on the box body, so that the detection results can be accurately and reliably judged according to the displayed color without manual operating error; and the time for detecting the mycobacterium tuberculosis antibody is greatly shortened, and the detection is rapid, simple and onsite without needing expensive instruments and professional training to operating personnel.
