Abstract:
1. A method for determining the concentration or activity of an analyte in a sample, the method comprising: mixing a sample with at least one reagent, whereby an analyte-dependent reaction is set in motion; measuring a signal (x) changing over time (t) as a result of the analyte-dependent reaction and storing a resultant signal-time curve; determining a maximum increase in the signal-time curve; determining a reaction lag phase of the signal-time curve; and determining a concentration or activity of the analyte by means of at least one parameter of the signal-time curve, wherein the parameter occurs after the reaction lag phase in terms of time, and wherein determining the reaction lag phase includes determining a period of time from a time of a first signal (t by determining a time t subsequently determining from the time t curve for the first time reaches a threshold value and where the threshold value corresponds to a test-specific, predetermined fraction of the maximum increase in the signal-time curve.
