摘要

A method for determining the concentration of an analyte in a sample from the analyte and a sample matrix using capillary, taking into account the sample amount in an evaluation area of a test element, comprising the steps of– Irradiation of the sample with radiation in a control - wavelength range, which on a test area of the test element was placed, so that at least one evaluation area of the test field of the radiation is detected, wherein the test field contains a control substance with the sample matrix using capillary of the sample interacts in the manner that the control substance with the radiation in the control - wavelength range as a function of the contact interacts with the sample matrix using capillary,– Detection of the radiation which has interacted with the control substance for generating a detection value,– Determination of the amount of sample in the evaluation region by comparing the detected radiation with a previously known detection value of the control substance in the case of a known amount of sample in the evaluation region,– Determination of the concentration of the analyte in the sample under consideration of the determined amount of sample.
