  • Patent number: 11189056
    Abstract: A method for evaluating the suitability of a mobile device having a camera for performing an analytical measurement based on a color formation reaction. A mobile device is provided and is used to take an image of a reference color field of an object. A color coordinate of pixels of a region of interest within the image is determined and a histogram analysis is performed on a distribution of the color coordinates of the pixels. The width of a color peak within the distribution from the histogram analysis is ascertained and compared with a threshold value to thereby determine suitability of the mobile device for performing the analytical measurement based on the color formation reaction.

  • Publication number: 20210285888
    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.

  • Patent number: 11120553
    Abstract: A method for evaluating the suitability of a mobile device having a camera for performing an analytical measurement is disclosed. The method includes providing the mobile device and providing a reference object having a predefined spatial extension in a spatial dimension. An image is taken of at least part of the reference object using the camera and is used to derive spatial resolution information that includes one or more numerical values that quantify the capability of the camera to resolve two or more objects in the image. A threshold value based on a minimum number of pixels in the spatial dimension within a region of interest in the image is provided and the spatial resolution information is compared with the threshold value. It is determined from the comparison whether the mobile device is suitable for performing the analytical measurement.

  • Publication number: 20210255111
    Abstract: A method of performing an analytical measurement based on a color formation reaction in an optical test strip using a mobile device having a camera. In the inventive method, an optical test strip having a test field is provided. A first image of at least part of the test field is captured using the camera with an image acquisition setting of the camera, and the image acquisition setting is locked. A sample of body fluid is applied to the test field and then there is a step of waiting a predetermined minimum amount of time. Then, while the image acquisition setting remains locked, a second image of at least part of the test field is captured using the camera with the same image acquisition setting of the camera used to capture the first image. An analytical measurement result value is then determined by using the first and the second images.

  • Patent number: 11067588
    Abstract: A method for operating a medical analyte testing system having a handheld meter, particularly, a glucose meter, and a test magazine is disclosed. In the disclosed method a replaceable test magazine including a plurality of test elements is provided in the handheld meter for conducting successive analyte tests. An auxiliary measuring unit of the handheld meter measures at various points of time at least one ambient parameter, including temperature or humidity. The method checks for a threshold violation by comparing the measured ambient parameter with a preset threshold. The preset threshold is lowered after an initial period of use of the test magazine, and a use-up period is adjusted based on the check for a threshold violation.

  • 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: 20210096083
    Abstract: A method for calibrating a camera of a mobile device for detecting an analyte in a sample. An image of an object is captured using the camera with an illumination source turned on. A first area is determined in the image which is affected by direct reflection of light originating from the illumination source and reflected by the object. A second area which does not substantially overlap with the first area is determined as a target area of a test strip. Also disclosed is a detection in which a sample is applied to a test strip and a visual indication is provided to position the test strip relative to the camera to thereby locate the test field of the strip in the target area. An image of the test field is captured using the camera while the illumination source is turned on, and analyte concentration is determined from the image.

  • Publication number: 20210088506
    Abstract: A method of evaluating suitability of lighting conditions for detecting an analyte in a sample using a mobile device camera. A test strip is provided for detecting the analyte. A first image of the test strip is captured while an illumination source of the mobile device is turned off and a second image of the test strip is captured while the illumination source is turned on. A sample is applied to the test strip and the first and second images are compared to thereby determine the difference in lighting conditions between the first image and the second image. The comparison is used to derive information on suitability of the lighting conditions for analyte detection. The lighting conditions are indicated as suitable when a predetermined threshold amount of light intensity used for illumination of the test strip originates from the illumination source.

  • Publication number: 20200386672
    Abstract: A calibration method for calibrating a camera for detecting an analyte in a sample is disclosed. A plurality of different color coordinate systems and a set of test samples are provided. The test samples are applied to test elements that have test fields for producing an optically detectable reaction. Images of the colored test fields are acquired using the camera and color coordinates for the images are generated. The color coordinates that are generated are transformed into a set of measured concentrations by using a set of coding functions. The set of measured concentrations is compared with the known concentrations of the test samples and a best match color coordinate system of the plurality of color coordinate systems is determined. A best match coding function of the plurality of coding functions is also determined.

  • Publication number: 20190239781
    Abstract: Disclosed is a method of using a handheld meter configured for determining an analyte concentration in a body fluid. In the inventive method, a handheld meter with a disposable test element is provided and the test element is positioned at an application site of the meter. A body fluid from a user's body part is applied to a reaction area of the test element and a series of measurement values from the reaction area of the test element is detected. A proximity sensor senses the presence of the body part in a monitored space in proximity to the reaction area of the test element. The measured values are processed as a function of an output signal of the proximity sensor. Consequently, bias in the determination of the analyte concentration caused by the presence of the body portion is reduced or eliminated. An associated handheld meter is also disclosed.
