Abstract

La presente invención se refiere a un método para realizar una medición analítica sobre la base de una reacción de formación de color en una tira reactiva óptica (116) usando un dispositivo móvil (112) que tiene una cámara (114), además de un programa informático que incluye instrucciones ejecutables por computadora para realizar el método. También se describen un dispositivo móvil y un kit para realizar una medición analítica. El método comprende la etapa a): proporcionar una tira reactiva óptica (116) que tiene un campo de prueba (118) sin tener una muestra aplicada a este; la etapa b): capturar al menos una primera imagen de al menos parte del campo de prueba (118) de la tira reactiva óptica (116) sin tener una muestra aplicada a este, usando la cámara (114) con al menos una configuración de adquisición de imagen de la cámara (114), específicamente con un conjunto de configuraciones de adquisición de la cámara (114); la etapa c): aplicar una muestra, específicamente una gota, de líquido corporal al campo de prueba (118) de la tira reactiva óptica (116); la etapa d): esperar una cantidad de tiempo mínima predeterminada; la etapa e): capturar al menos una segunda imagen de al menos parte del campo de prueba (118) de la tira reactiva óptica (116) que tiene la muestra de líquido corporal aplicada a este usando la cámara (114) con una o más configuraciones de adquisición de imagen de la cámara (114), en donde las configuraciones de adquisición de imagen de la cámara (114) son las mismas configuraciones de adquisición de imagen de la cámara (114) que se usan en la etapa b); y la etapa f): determinar un valor de resultado de medición analítica usando la primera y la segunda imagen del campo de prueba óptica (118) de la tira reactiva óptica (116), específicamente comparando al menos las dos imágenes.
