It is intended to provide a detection method and a determination method for detection target capable of detecting and determining a detection target promptly and simply with high accuracy at low cost. The detection method includes the steps of: mixing a first conjugatein which a first substance containing a stimulus-responsive polymerand a particulate magnetic substanceis conjugated to a first antibodyagainst a detection targetwith a sample; applying a magnetic force after placing the resulting mixture in a condition capable of aggregating the stimulus-responsive polymer; measuring a generated magnetic field; and detecting the detection targetbased on the degree of increase in the magnetic field after applying the magnetic force.

Detection method and determination method for detection target

A detection/determination kit with which a substance to be detected or the amount thereof can be rapidly, inexpensively, and easily detected or determined; and a detection/determination method. The kit, which is for detecting a substance to be detected () contained in a specimen, comprises: a first compound () comprising a first substance including a stimulus-responsive polymer () and, bonded to the first substance, a first antibody () against the substance (); and a second compound () comprising a second substance () which is hydrophilic and, bonded thereto, a second antibody () against the substance (). The first antibody () and second antibody () can simultaneously combine with the substance () at different sites in the substance ().
