<P>PROBLEM TO BE SOLVED: To improve calibration accuracy to seasonal and psychological variation of tissue property. <P>SOLUTION: A noninvasive measurement instrument has a measurement probe 1 supposed to get into touch with a trial subject, a light source 6 and a photodetector 7 to be connected to the measurement probe, and a computer section 5 for controlling the light source and photodetector to optically and noninvasively measure information relating to glucose in the trial subject and predict the value of glucose by a calibration model from an output of the photodetector. The computer section updates the calibration model by executing regression estimation based on the acquired data by noninvasive measurement on a different day and the corresponding reference measurement value and predicts glucose density from the acquired data by noninvasive measurement by using the updated calibration model. <P>COPYRIGHT: (C)2012,JPO&INPIT |
