1. An analysis system for determining an analyte in a body fluid, comprising:

  • a test element with a reagent system, whose reaction with the analyte results in a detectable change which is characteristic for the desired analytical result, with a sample application zone and with two analysis zones, andan analysis instrument with a measurement and evaluation unit, which comprises;

    two analog measuring units, in each of which an analog measurement signal corresponding to one of the analysis zones is generated,two analog-digital converters for digitizing the analog measurement signal,a comparator unit for comparing control data values based on the digitized measurement signals, anda final processing unit, in which, if a determined deviation between the control data values of the digitized measurement signals is less than a predefined value, at least one of the control data values is allowed to pass for further processing into the desired analytical result.
