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) doté d'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) comportant 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), le procédé comprenant : i) la fourniture, dans le dispositif mobile (112), d'au moins une corrélation pour transformer la formation de couleur du champ de test (126) en valeur de concentration d'analyte, le terme « corrélation » faisant référence à une relation prédéterminée ou déterminable entre des informations dérivées de l'au moins une image et au moins une valeur de concentration de mesure analytique, la corrélation étant déterminée en utilisant des méthodes empiriques ou semi-empiriques, également appelées apprentissage ; ii) la fourniture, dans le dispositif mobile (112), d'au moins un élément d'information de clairance, l'au moins un élément d'information de clairance indiquant un niveau de confiance pour la corrélation ; et iii) si l'élément d'information de clairance indique un niveau de confiance suffisant pour la corrélation, la fourniture, par le dispositif mobile (112), d'une indication à un utilisateur que la capture de l'au moins une image ne nécessite pas l'utilisation de la carte de référence de couleur (128).<h3>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 permettant d'effectuer et/ou de contrôler des mesures analytiques.</h3>
