<p>Disclosed is a device for estimating blood sugar level whereby a blood sugar level is non-invasively calculated over time based on optical spectra of a living organism, that are measured over time, and calibration models. This device is provided with a means for forming calibration model whereby a calibration model is formed from multiple calibration models or multiple data sets for forming calibration model. The device is constituted to set a standard spectrum by measuring a biological spectrum of a subject, to determine a differential spectrum that is the difference between a measurement spectrum measured at a point other than the measuring point of said standard spectrum and said standard spectrum, and to change the calibration model to be used in said calculation depending on a change in said differential spectrum. Thus, a blood sugar level can be estimated at an extremely high accuracy, particularly in the case of monitoring over time.</p> |
