Device and method for assaying biological components in sample

摘要

The invention relates to an assay device comprising a sample-receiving port (1), a pump-connection port (6), a sample-treating zone (2) which is provided with a labelled substance with a label, a sample-treating and optical-measuring zone (3) which has a porous material having immobilized thereto one of a specifically binding pair, and a pathway interconnecting these zones and ports, wherein the sample-treating zone (2) and the sample-treating and optical-measuring zone (3) are positioned between the sample-receiving port (1) and the primp-connection port (6); or comprising a sample-receiving port, a pump-connection port, a sample-treating and optical-measuring zone which has a porous material having immobilized thereto a labelled substance with a label and one of a specifically binding pair, and a pathway interconnecting these zone and ports, wherein the sample-treating and optical-measuring zone is positioned between the sample-receiving port and the pump-connection port. Using the assay device according to the invention, biological components can be quantitatively determined by immunoassay in a simple manner. <IMAGE>
