TEST STRIP AND METHOD FOR MEASURING AN ANALYTE CONCENTRATION IN A SAMPLE OF A BIOLOGICAL FLUID

摘要

Disclosed is a method for measuring a concentration of an analyte contained in a sample of a biological fluid. In said method, a test strip (1) is provided which comprises at least one test point and at least one reference color section encompassing the color white and/or a color scale. The fluid sample is brought in contact with the test point, and a color indicator is disposed on the test point in accordance with the concentration of the analyte. A camera (8) is placed on the test strip (1). At least one measured value is detected for the relative position between the camera (8) and the test strip (1) and is compared to a set value range. If the measured value deviates from the set value range, the camera (8) is moved relative to the test strip (1) to reduce the deviation. A colored image on which at least the color indicator (3) and the reference color section (4) are represented is detected with the aid of the camera (8). The image areas assigned to the color indicator (3) and the color matching section (4) are located, and the color values of said image areas are determined. The analyte concentration in the sample is determined based on the color values with the aid of predefined comparative values.
