Abstract
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 having an additive-impregnated part between a sample introducing part and a determining part, the additive-impregnated part 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 in order to move with the movement of the sample through the carrier. The porous carrier also has a labelled part segmented into plural zones.
