Abstract

L'invention concerne un procédé de détermination d'une concentration d'un analyte dans un fluide corporel. Le procédé comprend l'utilisation d'un dispositif mobile (112) ayant une caméra (114). En outre, le procédé comprend la capture d'au moins une image d'au moins une partie d'une bandelette de test optique (124) ayant un champ de test (126) à l'aide de la caméra (114). Le procédé comprend en outre la détermination d'au moins une valeur de concentration d'analyte à partir de la formation de couleur du champ de test (126), dans lequel le procédé comprend :i) la fourniture, dans le dispositif mobile (112), d'au moins une corrélation pour transformer la formation de couleur du champ de test champ (126) dans la valeur de concentration d'analyte ;ii) fournir, dans le dispositif mobile (112), au moins un élément d'information de clairance, le au moins un élément d'information de clairance indiquant un niveau de confiance pour la corrélation ; etiii) si l'information d'autorisation indique un niveau de confiance suffisant pour la corrélation, fournir, par le dispositif mobile (112), une indication à un utilisateur que la capture de la au moins une image ne nécessite pas l'utilisation de la carte de référence de couleur ( 128).En outre, l'invention concerne un procédé de contrôle de mesures analytiques, un dispositif mobile (112), un système (110) de contrôle de mesures analytiques et des programmes informatiques pour effectuer et/ou contrôler des mesures analytiques.
