Abstract: A method of performing an analytical measurement includes using a camera of a mobile device to capture a time series of images of at least a part of a medical article. From this, image-derived position information on a relative position of the mobile device and the medical article is derived, thereby generating a first time series of position information. A sensor captures measurement information on the relative position of the mobile device and the medical article. Measurement-derived position information is used to generate a second time series of position information, and the first and second time series of position information are combined to generate an augmented time series of position information. From this, guidance is provided to a user to move the mobile device and the medical article into a relative target position. A mobile device, a kit and a computer program are also disclosed.

Abstract: A method for determining analyte concentration in a body fluid using a mobile device having a camera and a lidar sensor that have an overlapping field of view. In the method, an object is selected and the user is prompted to apply a body fluid sample to a reagent test region. The user is prompted to provide the object within the overlapping field of view of the camera and the lidar sensor. The processor of the mobile device generates a lidar measurement data set representing the object, which is compared to a pre-generated data set. When there is a degree of congruence from the comparison that is above a pre-determined minimum, the camera captures an image of the reagent test region having the body fluid sample applied thereto and concentration of analyte in the sample is determined. When the congruence is below a pre-determined minimum, image capturing is not allowed.

Abstract: A method of controlling auto white balance settings of a mobile device with a camera and preset auto white balance modes for performing a color based measurement comprising the steps of capturing an image of at least part of one or more gray fields of a color reference card, determining, for a region of interest within the image, a number of gray fields for which the color information for a first color and a second color shows overexposure as a first overexposure-number and a second overexposure-number, respectively, the first color relating to a smaller wavelength than the second color, and re-capturing the image with a warmer white balance mode if the first overexposure number is greater than the second overexposure number or re-capturing the image with a cooler white balance mode if the first overexposure number is smaller than the second overexposure number.

Abstract: A method of determining concentration of an analyte in a body fluid uses a mobile device having a camera and an ambient light detector. The ambient light detector has an ambient light sensor and/or an additional camera. An ambient light check is performed. In the ambient light check, ambient light is used to determine an item of ambient light information. If a validity criterion is determined to be met, the concentration of the analyte is determined by evaluating an image of at least a part of a reagent test region of an optical test strip having a sample of body fluid applied thereto. The image is captured by the camera. A mobile device, a kit, a computer program and a computer-readable storage medium are also disclosed.

Abstract: A method of performing an analytical measurement based on a color formation reaction in an optical test strip by using a mobile device having a camera. An optical test strip having a test field is provided. The camera captures a first image of at least part of the test field before a sample is applied and a second image after the sample is applied. The mobile device indicates where to take the second image so that the first and second images are taken at similar local positions with respect to at least one environmental feature that has a fixed and/or unchanged position between the capturing of the first and second images. An analytical measurement result value is then determined by using the first and second images. A computer program, a computer-readable storage medium, a mobile device and a kit for performing an analytical measurement are also disclosed.

Abstract: A method of performing an analytical measurement based on a color formation reaction in an optical test strip by using a mobile device having a camera, a display and a position sensor. An optical test strip having a test field is provided. The camera captures a first image of the test field before a sample is applied and a second image after the sample is applied. An item of admissibility information, based on one or both of position sensor data and local position data, is determined. Admissibility is indicated when the position of the mobile device is substantially the same for capturing the first and the second image. When admissibility is indicated, an analytical measurement takes place. Further, a computer program, a computer-readable storage medium, a mobile device and a kit are disclosed.
