| description | The present invention relates to an immunochromatographic assay device, comprising: a cover plate; an immunochromatographic assay kit; and a sample loading pad. A wet zone is defined by the cover plate and at least part of a sample loading portion of the sample loading pad disposed close to an installation position of the immunochromatographic assay kit. The height of the wet zone satisfies the following condition: when flowing into the wet zone, a sample solution is driven by capillary action to flow from a surface of the sample loading portion toward the immunochromatographic assay kit. A wet zone having a certain length is arranged in front of a sample loading zone of an immunochromatographic assay kit, such that when a sample solution flows into the wet zone, capillary action drives the sample solution to flow into the wet zone, thereby increasing a flow speed of the sample solution in the wet zone, allowing substantially simultaneous sample loading on immunochromatographic assay kits at different installation positions, and accordingly enhancing the consistency and uniformity of sample loading. |
