Analysis system for determining an analyte of a body fluid, comprising a test element (3) and an analysis instrument (2) having a measurement and evaluation unit (4). The test element has a sample application zone (8) and two analysis zones (9a, 9b) and a reagent system, whose reaction with the analyte results in a detectable change characteristic for the desired analytical result. The measurement and evaluation unit (4) comprises two analog measuring units (10a, 10b), in each of which an analog measurement signal (11a, 11b) corresponding to one of the analysis zones (9a, 9b) is generated, two analog-digital converters (12a, 12b) for digitizing the analog measurement signal (11a, 11b), a comparator unit (13) for comparing control data values (17a, 17b) based on the digitized measurement signals (16a, 16b), and a final processing unit (15), in which, if the determined deviation between the control data values (17a, 17b) of the digitized measurement signals (16a, 16b) is less than a predefined value, at least one of the control data values (17a, 17b) is allowed to pass for further processing into the desired analytical result (6).
