Abstract

La présente invention concerne un procédé par lequel un terminal utilisateur effectue une analyse urinaire, selon un mode de réalisation, comprenant les étapes de : (a) photographie d'une bande de test d'urine à laquelle l'urine est appliquée, afin de générer une image de test ; (b) extraction, depuis l'image de test, d'une valeur RGB pour chacune d'une pluralité de zones tampons correspondant à chaque zone d'élément de test de la bande de test d'urine, afin de générer une première valeur RGB ; et (c) et génération d'une première valeur de ratio à travers la première valeur RGB et d'une valeur RGB de densité spécifique extraite de la zone tampon d'une densité spécifique parmi des éléments de test, et comparaison d'une seconde valeur de ratio, qui est le ratio entre une densité spécifique calculée et chaque élément de test, et la première valeur de ratio à travers un tableau colorimétrique standard afin de calculer une valeur numérique pour chaque élément de test, le tableau colorimétrique standard définissant toutes les couleurs que la zone tampon correspondant à chaque élément de test peut exprimer.
