    Abstract: A method for analyzing at least one sample of a body fluid, for example determining blood glucose concentration, is proposed. The method comprises the following steps: a) recording a plurality of measurement values by monitoring a time development of at least one measurement value indicating a progress of a detection reaction of at least one test substance (126) and the sample of a the body fluid, and providing at least one measurement curve F(t) which contains the measurement values, wherein at least an evaluation part of the measurement curve has an exponential characteristic, wherein the measurement values contained in the measurement curve are acquired at differing points in time, wherein the detection reaction is known to be influenced by a concentration c of an analyte to be detected in the body fluid and at least one disturbance variable Y; b) deriving an end value of the measurement curve, wherein the end value forms a first variable x1; c) deriving at least one fit parameter from the measurement curve by taking into account the exponential characteristic of at least the evaluation part of the measurement curve, wherein the fit parameter forms at least one second variable x2; d) deriving the concentration c of the analyte by using at least one multivariate evaluation algorithm, the multivariate evaluation algorithm being adapted to combine the first variable x and the second variable x2.

    Abstract: A sensor device (112) for detecting at least one analyte in a body fluid of a user is disclosed. The sensor device (112) comprisesat least one evaluation device (134) configured for evaluating a data stream of time-dependent concentrations c of the analyte.The evaluation device (134) comprises at least one comparator device (140) configured for comparing a current value c(t) of the concentration cwith at least one first threshold value L and with at least one second threshold value H, with H > L. The evaluation device (134)is configured to define a tolerance time interval(158). Further, the evaluation device (134), by using the comparator device (140), is configuredto detect if the concentrationcrises and exceeds the first threshold value L during the tolerance time interval (158)and to prepare a warning signal W accordingly. Theevaluation device (134)is configured to suppressan output of the warning signal W at least until the tolerance time interval (158) expires, under the precondition that c(t)
