METHODS AND DEVICES FOR CARRYING OUT ANALYTICAL MEASUREMENTS Russian patent published in 2023 - IPC G01N21/84 G01N33/48 

FIELD: methods of analytical measurement.

SUBSTANCE: claimed group of inventions relates to a method for carrying out an analytical measurement based on the reaction of colour formation in an optical test strip using a mobile device with a camera, a computer program with software for performing this method, a mobile device and a kit for carrying out an analytical measurement that can be used in medical diagnostics, to qualitatively or quantitatively determine one or more analytes in one or more body fluids. The claimed method includes step a): providing an optical test strip (116) having a test field (118) without a sample applied to it; step b): acquisition of at least one first image of at least part of the test field (118) of the optical test strip (116) without a sample applied to it using a camera (114) with at least one camera image acquisition setting (114), in particular, with a set of camera image acquisition settings (114); step c): applying a sample, in particular a drop of physiological fluid, to the test field (118) of the optical test strip (116); step d): waiting for a predetermined minimum time; step e): obtaining at least one second image of at least a part of the test field (118) of the optical test strip (116) with a sample of physiological fluid applied to it using a camera (114) with one or more camera image acquisition settings (114), wherein the camera image acquisition settings (114) are the same as the camera image acquisition settings (114) used in step b); and step e): determining the value of the analytical measurement result using the first and second images of the optical test field (118) of the optical test strip (116), in particular by comparing at least two images.

EFFECT: increased accuracy of measurements and increased reliability, while providing ease of use for the user.
