摘要： 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 conjugate 10 in which a first substance containing a stimulus-responsive polymer 11 and a particulate magnetic substance 19 is conjugated to a first antibody 13 against a detection target 50 with a sample; applying a magnetic force after placing the resulting mixture in a condition capable of aggregating the stimulus-responsive polymer 11; measuring a generated magnetic field; and detecting the detection target 50 based on the degree of increase in the magnetic field after applying the magnetic force.
