Abstract
A method of determining a calibration curve used in deciding the components of living organism by means of the least-squares method by using a plurality of measured data at different concentrations obtained by measuring reaction solutions of a plurality of standard substances having different concentrations. At least a single set of measured data Y(i) is weighted in a predetermined manner, the measured data Y(i) being obtained from the standard substance reaction solution at a specific concentration X(i) near a limit value used in deciding the living organism components. With the weighting, a calibration curve having a high precision at a portion near the limit value is realized resulting in a correct and highly reliable decision.
