摘要

An immunochromatography-assisted device is disclosed which facilitates accurate and rapid detection of an antigen contained in a fluid sample and from which background coloring and blank coloring possibly causing a malfunction at detection are successfully eliminated. The immunochromatography-assisted device comprises a porous carrier (10) having an additive-impregnated part between a sample introducing part (11) and a determining part (14), the additive-impregnated part (12) carrying at least one selected from the group consisting of a surfactant, a water-soluble ammonium salt and a pH buffer such that it dissolves in a sample introduced into the carrier (10) in order to move with the movement of the sample through the carrier (10). The porous carrier (10) also has a labelled part (13) segmented into plural zones. IMAGE
