Method for predicting a blood glucose level of a person

Abstract

A method for predicting blood glucose level of a person includes performing on the person a near-infrared spectral scan of a body part at a first group of wavelengths and at a second group of wavelengths, determining a first group of near-infrared absorbance values for the first group of wavelengths and a second group of near-infrared absorbance values for the second group of wavelengths, determining a first difference for the first group of near-infrared absorbance values and a second difference for the second group of near-infrared absorbance values, and (4) calculating a blood glucose level for the person using the first and second differences. 一种用于预测人血糖水平的方法，包括：对所述人在第一组波长和第 二组波长下进行身体局部的近红外光谱扫描，确定对应于所述第一组波长 的第一组近红外吸收值和对应于所述第二组波长的第二组近红外吸收值， 确定对应于所述第一组近红外吸收值的一阶差分和对应于所述第二组近 红外吸收值的二阶差分，和(4)利用所述一阶差分和二阶差分计算所述人的血糖水平。
