Abstract
(EN) An apparatus includes a mobile computing device (902) physically coupled to a lightbox (904). The apparatus includes camera hardware configured to capture image data associated with an output signal area of a biological chromatographic test strip (410) inserted into a receiving slot of the lightbox. The apparatus further includes processing circuitry in communication with the camera hardware, the processing circuitry being configured to determine, based on the image data captured by the camera hardware, a concentration of a target analyte in a test sample submitted via the biological chromatographic test strip. The apparatus further includes an interface in communication with the processing circuitry, the interface being configured to output data indicative of the concentration of the target analyte determined by the processing circuitry.
(FR) Un appareil comprend un dispositif informatique mobile (902) physiquement couplé à un caisson lumineux (904). L'appareil comprend un matériel de caméra configuré pour capturer des données d'image associées à une zone de signal de sortie d'une bandelette de test chromatographique biologique (410) insérée dans une fente de réception du caisson lumineux. L'appareil comprend en outre des circuits de traitement en communication avec le matériel de caméra, les circuits de traitement étant configurés pour déterminer, sur la base des données d'image capturées par le matériel de caméra, une concentration d'un analyte cible dans un échantillon de test soumis par le biais de la bandelette réactive de chromatographie biologique. L'appareil comprend en outre une interface en communication avec les circuits de traitement, l'interface étant configurée pour délivrer des données indicatives de la concentration de l'analyte cible déterminée par les circuits de traitement.
