<p>Disclosed is a sample extract that can simply and inexpensively minimize false positive reactions, which were not able to be minimized using conventional methods, relating to a virus measurement immunochromatographic reagent, which detects by the immunochromatographic method viruses in such samples as nasal cavity swabs, nasal aspirates, nasal blows, and pharyngeal swabs. The sample extract contains the false positive reaction inhibitor, which contains a component that controls the affinity between the anti-detection test substance antibody and the false positive reaction source component, which has the following properties 1-3: 1) is included in a sample derived from the nasopharynx, 2) is not the detection test substance, and 3) has affinity with the anti-detection test substance antibody.</p> |
