  • Publication number: 20210295515
    Abstract: A method for generating a module configured to determine concentration of an analyte in a sample of a body fluid is disclosed. The method includes providing a first set of measurement data derived from images of one or more test strips indicating a color transformation in response to a body fluid containing an analyte. The images can be recorded by multiple devices with differing cameras, software and/or hardware device configurations for image recording and image data processing. A neural network model can be generated in a machine learning process applying an artificial neural network and a module configured to determine concentration of an analyte in a second sample of a body fluid can be generated. Further, the present disclosure includes a system for generating the module as well as a method and a system for determining concentration of an analyte in a sample of a bodily fluid.

  • Publication number: 20210258565
    Abstract: A method of evaluating the suitability of a mobile device for performing an analytical measurement based on a color formation reaction. The capability of the mobile device to have relevant settings of the mobile device controlled by software running on the mobile device is evaluated. The relevant settings pertain to image raw data processing steps to be carried out by the mobile device and may include a color space transformation and a tone mapping transformation. When the evaluation indicates that the mobile device is capable of having the relevant settings controlled by the software, control information indicating that the mobile device is suitable for performing the analytical measurement is provided. When the evaluation indicates that the mobile device is not capable of having the relevant settings controlled by the software, control information indicating that the mobile device is unsuitable for performing the analytical measurement is provided.

  • Publication number: 20210131973
    Abstract: A method for detecting an analyte in a sample is disclosed. The method includes providing a mobile device having a camera and an illumination source. A test strip having a test field with at least one test chemical for performing an optical detection reaction in the presence of the analyte is provided. The sample is applied to the test field. Several images of a region of the test strip are captured. The region includes at least part of the test field to which sample is applied. The images are captured before and after the sample is applied and with the illumination source turned on and off. The images captured are compared and differences in light intensities are determined. Analyte concentration is determined using the images captured and the determined light intensities.

  • Publication number: 20200275868
    Abstract: A glucose test arrangement is provided for use in a handheld meter. The arrangement comprises a disposable test pad responsive to glucose in a body fluid, and a supporting member adapted to support the test pad at an application site for applying body fluid from a user's skin onto a receiving area of the test pad. The receiving area faces away from the supporting member. One or more spacer elements are arranged on the supporting member adjacent to the test pad, wherein the one or more spacer elements have a skin-contacting end section which protrudes above the receiving area.
