PROBLEM TO BE SOLVED: To provide a test piece for immunochromatography, capable of suppressing backflow of a labeling reagent in a membrane and improving accuracy and reliability of detection or measurement.SOLUTION: The test piece for immunochromatography includes a sample pad to which a specimen is given, a membrane on which a test region for capturing a composite of a labeled particle and a labeled substance is formed and an absorption pad for absorbing and holding a shifted labeled particle. In the test piece, a relapse preventing region is formed in the front of the test region in a shift direction of labeled particles, a relapse preventing capturable substance for capturing the labeled particles is arranged in the relapse preventing region, and in the relapse preventing region, the labeled particles passed through the test region are captured to prevent relapse of the labeled particles to the test region. |
