Abstract

La presente invención se refiere a un método (110) para evaluar una adecuación de condiciones de iluminación para detectar un analito en una muestra usando una cámara (112) de un dispositivo móvil (114). El método comprende las siguientes etapas: a) (117) capturar al menos una primera imagen de al menos una tira de prueba (116), en donde la tira de prueba (116) se adapta para detectar el analito en la muestra, la tira de prueba (116) tiene al menos un campo de prueba (118) que comprende al menos un producto químico de prueba para llevar a cabo una reacción de detección óptica en presencia del analito, en donde, durante la captura de la primera imagen, se apaga una fuente de iluminación (120) del dispositivo móvil (114); b) (122) capturar al menos una segunda imagen de la tira de prueba (116), en donde, durante la captura de la segunda imagen, se enciende la fuente de iluminación (120) del dispositivo móvil (114); c) (124) comparar la primera y segunda imágenes capturadas en las etapas a) (117) y b) (122), de este modo, determinar una diferencia en las condiciones de iluminación entre la primera imagen y la segunda imagen; y d) (126) derivar al menos una información sobre adecuación a partir de la comparación en la etapa c) (124), en donde la información sobre adecuación comprende información sobre una adecuación de condiciones de iluminación para la detección de analitos.
