Title
(EN) DETERMINATION OF A CONCENTRATION OF AN ANALYTE IN A BODILY FLUID BY USING A MOBILE DEVICE WITH A CAMERA
(FR) DÉTERMINATION D'UNE CONCENTRATION D'UN ANALYTE DANS UN FLUIDE CORPOREL EN UTILISANT UN DISPOSITIF MOBILE AYANT UNE CAMÉRA
Abstract
(EN)
A method of determining a concentration of at least one analyte in a bodily fluid by using a mobile device (112) and a test element (114) is disclosed. Further disclosed are a mobile device (112), a kit (110) and a computer-readable storage medium. The method comprises: a) determining an angular orientation of the mobile device (112) relative to the test element (114) by using sensor data of at least one sensor device (120) integrated into the mobile device (112); b) subjecting the angular orientation of the mobile device (112) relative to the test element (114) to at least one validity test; c) capturing at least one image (128) of at least a part of the test element (114) by using the camera (118), the at least one part of the test element (114) comprising at least one part of the test field (116); and d) determining the concentration of the analyte in the bodily fluid from the image (128); wherein at least one of steps c) and d) is performed by taking into account the result of the validity test in step b).

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).
