METHOD FOR THE EVALUATION OF THE QUALITY OF A TEST ELEMENT

摘要

The present invention relates to a method for evaluating the quality of an analysis element which is useful for determining the concentration of an analyte in a liquid sample, and to an analysis system which implements such a method. A reaction of the sample with a reagent system includes a complex formation of at least an enzyme and a co-enzyme, wherein a chemically modified form of the co-enzyme is a fluorophore. The quantity and/or the luminescence properties of said fluorophore relate to the concentration of the analyte. The quality of the analysis element is evaluated using an evaluation algorithm, wherein the evaluation algorithm comprises obtaining information relating to a measured enzyme activity AEnz(measured), wherein said information is at least partly derived from a measurement of the fluorescence lifetime of the fluorophore.
