Abstract
L'invention concerne un procédé de détermination d'une concentration d'au moins un analyte dans un fluide corporel à l'aide d'un dispositif mobile (112) et d'un élément de test (114). L'invention concerne également un dispositif mobile (112), un kit (110) et un support de données lisible par ordinateur. Le procédé consiste à : a) déterminer une orientation angulaire du dispositif mobile (112) par rapport à l'élément de test (114) en utilisant des données de capteur d'au moins un dispositif capteur (120) intégré dans le dispositif mobile (112) ; b) soumettre l'orientation angulaire du dispositif mobile (112) par rapport à l'élément de test (114) à au moins un test de validité ; c) capturer au moins une image (128) d'au moins une partie de l'élément de test (114) à l'aide de la caméra (118), l'une ou les parties de l'élément de test (114) comprenant au moins une partie de la zone de test (116) ; et d) déterminer la concentration de l'analyte dans le fluide corporel à partir de l'image (128) ; au moins l'une des étapes c) et d) étant réalisée en prenant en compte le résultat du test de validité à l'étape b).
