| abstract |
The invention relates to a method, to a test element (50), and to a device (190) 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 (110) of a bodily fluid, wherein at least one test element (50) having at least one test chemistry (102) is used, wherein at least one reaction of the test chemistry (102) with the analyte is detected. The invention further relates to at least one marker (104, 104'), wherein the marker (104, 104') is different from the analyte (117), wherein at least one diffusion of the marker (104, 104') in the sample (110) or at least one component of the sample (110) is detected. At least one piece of correction information is produced from the diffusion of the marker (104, 104'), wherein the concentration of the analyte is determined from the reaction of the test chemistry (102) with the analyte while taking into account the correction information. |
