Abstract
A method for the determination of an analyte in a liquid sample, especially a body liquid sample, with the aid of an analytical apparatus. The apparatus receives a first measuring signal si (i=0, 1, . . . ) and a second measuring signal sj (j=1, 2, . . . ; j>i) for a test system with several successively arranged measuring areas through which a liquid sample with an analyte can flow after being applied on the test system are received by an evaluation apparatus comprised by the analytical apparatus, wherein the first measuring signal si indicates a part of the analyte bound in a first measuring area and the second measuring signal sj indicates a part of the analyte bound in a second measuring area that is arranged downstream the first measuring area on the test system after the application of the liquid sample on the test system, a concentration measure N correlating with the concentration of the analyte in the liquid sample is determined by the evaluation apparatus in accordance with the following linkage of measuring signals:
the concentration measurement is outputted by the evaluation apparatus after a selective further processing. Furthermore, the invention relates to an analytical apparatus for the determination of an analyte in a liquid sample as well as to a computer readable medium for performing function to determine an analyte in a liquid sample.
