The present invention provides a method, test element 50, and device for determining at least one concentration of at least one analyte in a sample 110, in particular for detecting at least one metabolite in a sample of bodily fluid 110. 190, wherein at least one test element 50 with at least one test chemical 102 is used, wherein at least one reaction of the analyte with the test chemical 102 is detected. The invention also relates to at least one marker (104, 104'), wherein the marker (104, 104') is different from the analyte (117), wherein at least one of or in the sample (110) At least one diffusion of the markers 104, 104' in the component of is detected. At least one piece of calibration information is generated from the diffusion of the markers 104, 104', where the concentration of the analyte is determined from the reaction of the analyte and the test chemical 102 while taking the calibration information into account. |
