A METHOD AND A SYSTEM FOR DETERMINING A CONCENTRATION RANGE FOR A SAMPLE BY MEANS OF A CALIBRATION CURVE

摘要

The present invention relates to a method and a system for determining a concentration region for a measurement of a response value by means of a calibration curve, the calibration curve comprises response values as a function of concentrations. The method comprises providing a series of measured calibration data, fit a regression model to the provided series of measured calibration data; calculating a standard deviation for the measured calibration data; calculating a standard error for the measured calibration data; calculating a probability using the t-distribution with parameters from a group comprising: degrees of freedom, and the requested confidence interval; calculating a response value interval as a product of the standard error and the probability; applying the response value interval to the calibration model; measuring a response value for a sample; determining the concentration region by means of the response value interval and the calibration model.
