  • Publication number: 20240085340
    Abstract: A method of determining analyte concentration in a body fluid with a mobile device having a camera. A user is prompted to apply body fluid to an optical test strip and then waits a predetermined minimum waiting time. The camera captures an image of part of the test field having the body fluid applied thereto. Analyte concentration is determined based on the image captured. The determination includes estimating a point in time of sample application to the test field by taking into account time-dependent information derived from the image captured using a first color channel of a color space. The determination also estimates the concentration of the analyte by taking into account concentration-dependent information derived from the image using a second color channel of the color space.
