Abstract
MÉTODOS PARA DETERMINAR UMA CONCENTRAÇÃO DE UM ANALITO E PARA CONTROLAR MEDIÇÕES ANALÍTICAS, DISPOSITIVO MÓVEL,SISTEMA PARA CONTROLAR MEDIÇÕES ANALÍTICAS E PROGRAMAS DE COMPUTADOR. Divulga-se um método para determinar uma concentração de um analito em um fluido corporal. O método compreende usar um dispositivo móvel (112) com uma câmera (114). Além disso, o método compreende capturar pelo menos uma imagem de pelo menos uma parte de uma tira de teste óptico (124) com um campo de teste (126) usando a câmera (114). O método compreende ainda determinar pelo menos um valor de concentração analítica a partir da formação de cor do campo de teste (126), em que o método compreende: i)fornecer, no dispositivo móvel (112), pelo menos uma correlação para transformar a formação de cor do campo de teste (126) no valor de concentração analítica; ii)fornecer, no dispositivo móvel (112), pelo menos um item de informação de liberação, o pelo menos um item de informação de liberação indicando um nível de confiança para a correlação; e iii)se o item de informação de liberação indicar um nível de confiança suficiente para a correlação, fornecer, pelo dispositivo móvel (112), indicação a um usuário de que a captura da pelo menos uma imagem não requer usar o cartão de referência de cor (128). Além disso, são divulgados um método para controlar medições analíticas, um dispositivo móvel (112), um sistema (110) para controlar medições analíticas e programas de computador para realizar e/ou controlar medições analíticas.
