In a test strip measuring method in which a coloration measurement is conducted while a test strip (4) is being moved, there are detected the optical characteristics R of the ground of a test strip and the optical characteristics T of a test line (4b) which has appeared on the test strip, and the test strip is judged based on the difference or ratio between R and T. Even though the ground of the test strip presents variations in optical characteristics, and even though there are variations among samples or among test strips, such variations can be absorbed, thus assuring an accurate judgment.

Dans un procédé de mesure par bandelette de test où la coloration s'effectue pendant le déplacement de la bandelette de test (4), on détecte les caractéristiques optiques R du fond de la bandelette de test et les caractéristiques optiques T d'une ligne test (46) apparaissant sur ladite bandelette, ce qui permet de tirer une estimation de ladite bandelette de test sur la base de la différence ou du rapport existant entre R et T. Même lorsque le fond de la bande de test présente des variations en termes de caractéristiques optiques, et même lorsque les échantillons ou les bandelettes de test diffèrent, ces variations peuvent être gommées, ce qui garantit une estimation précise.
