METHOD FOR ANALYZING A SAMPLE OF A BODY FLUID

摘要

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.
