Abstract

La présente invention concerne un nouveau procédé de détection du sang occulte dans les selles, l'urine, les sucs gastriques et les expectorations. Ledit procédé représente un progrès dans le domaine de la recherche du sang occulte, en particulier sous une forme « d'autotest » simple à utiliser par les non-spécialistes. Le procédé peut être appliqué à un échantillon préalablement déposé dans une zone d'essai, par exemple une cuvette de toilettes, sans qu'il soit nécessaire de manipuler l'échantillon. Le procédé consiste à appliquer un agent oxydant, contenant de préférence un chélateur de métaux, à l'échantillon souhaité, puis à appliquer un composé chimiluminescent ou chimifluorescent. Il faut ensuite éliminer la lumière ambiante pour permettre de détecter la lueur chimiluminescente ou chimifluorescente à l'œil nu. Les composés chimiluminescents ou chimifluorescents de l'invention sont choisis parmi le luminol de sodium ou de potassium purifié et l'hydrazide de benzo(ghi)pérylène-(acide 1,2-dicarboxylique) de sodium ou de potassium purifié, à un pH supérieur à 9,0. L'utilisation de ces sels de sodium ou de potassium d'hydrazides génère, en présence de sang occulte, une chimiluminescence dont l'intensité est visible à l'œil nu, sans matériel de détection.
