<p>PROBLEM TO BE SOLVED: To provide a method for discriminating positive from false positive in a method of easily inspecting a plurality of detection objects by a membrane assay method using colored latex particles as a marker reagent.SOLUTION: First capture substances that specifically couple to the respective detection objects are rendered into solid phases in different positions on a membrane; two or more kinds of marker reagents are prepared by coupling colored latex particles having different tones by each detection object to a second capture substance; a mixture of a specimen liquid and the marker reagents is supplied and spread on the membrane; and the specimen liquid is determined in each determination section in the following way. When the color of the marker reagent corresponding to each determination section is detected, the detection object is determined as 'positive'; when the color of the marker reagent corresponding to each determination section is not detected, the detection object is determined as 'negative'; and when a tone (halftone) of the mixture of the marker reagents is detected in any one of the determination sections, the inspection is determined as 'invalid'.</p> |
