DETECTION SYSTEM OF TEST SUBSTANCE

摘要

A detection system of a test substance (10), includes: a magnetic body (2) that is modified by a first substance (3) capable of being bound to the test substance (10) at a first binding site of the test substance; a marker (4) that is modified by a second substance (3) capable of being bound to the test substance (10) at a second binding site of the test substance (10), the second binding site being a different site from the first binding site; a development medium (20) that has a flow passage (24) into which liquid, in which the magnetic body (2) and the marker (4) is dispersed, flows by a capillary phenomenon, the development medium having a detection position for detecting the marker (4) in a portion of the flow passage (24), the development medium having light transparency at least in the detection position; and a magnetic force generating portion (30) that is equipped in the development medium (20) in order to hold the magnetic body (2) in a portion of the flow passage (24).
