Abstract

The invention concerns a method and an apparatus for determining the concentration of an analyte in a body fluid, where the following measures are proposed: providing a layered test element (12) including an enzyme-based chemistry layer which is responsive to the analyte by a color change, applying a sample of the body fluid onto the test element (12), detecting by means of a photometric reflectance measuring device (16) a reflectance value of the test element (12), correcting the measured reflectance value by a predetermined offset value attributed to the test element (12), determining a concentration value of the analyte using the offset-corrected reflectance value.
