METHOD FOR EVALUATING MEDICAL MEASUREMENT CURVES

摘要

A method for detecting an analyte in a sample of a body fluid comprising the steps of: a) providing an optical measurement curve, which contains a plurality of measurement values recorded by monitoring a time development of a measurement value indicating a progress of a detection reaction of a test substance and the sample of a body fluid, wherein the detection reaction is known to be influenced by a set of state variables; b) providing a set of at least two different evaluation rules being adapted to derive a characteristic value from the optical measurement curve, thereby deriving a set of characteristic values X={Xi} i=1...N from the optical measurement curve; c) performing a multivariate analysis of the first and the second characteristic value by using a predetermined multivariate evaluation algorithm adapted to derive a result from at least two variables, wherein the at least one first and second characteristic value are used as the at least two variables, thereby deriving an estimate value for at least one target variable Y of the state variables; d) determining a concentration of the analyte by using the variable Y.
