Summary:The invention relates to a method for the determination of the concentration of a non-volatile analyte in an aqueous sample medium, with the use of an optical sensor which contains a luminescent dye and is calibrated at the user site by means of a single-point-calibration. To enable the user to completely dispense with all calibration media a luminescence measurement value is obtained at the user site with the sensor in contact with the aqueous or bloodlike sample medium, which value is referenced to the relative characteristic obtained at the factory site and to a measured dry calibration value obtained at the user site, the concentration of the non-volatile analyte being deduced from these data.
