Abstract: A multiassay immunochromatographic chip comprises: a viscous bottom lining (1), a sample pad (2), a bonding pad (3), an analysis membrane (4) and a water absorption pad (5). The bonding pad (3) fixedly has a plurality of assay binding substances (6) and a control binding substance (7), the assay binding substance (6) is formed by joining a tracer (8) and a liquid-phase detection probe (9), the control binding substance (7) is formed by joining the tracer (8) and a liquid-phase control probe (11); the analysis membrane (4) is provided with a detection matrix unit (12), each detection matrix unit comprises a detection zone (13) and a control zone (14), wherein the detection zone (13) consists of a plurality of solid phase detection probes (15) and the control zone (14) consists of a solid phase control probe (16). Organic integration of immunochromatographic reaction modes and chip assay matrix settings enables high throughput assay of multiple target substances with one sample load.
