Recently, lifestyle diseases (diabetics, hyperlipemia etc.) have been steadily increasing, because change of diet, lack of exercise, increase an alcoholic intake, and increase a stress. It is a matter of vital importance to us. About tens of millions of people in Japan have approached the danger of lifestyle diseases. So they have to do a blood test to make sure that they have controlled physical condition themselves. Therefore, they have to measure blood components again and again. So, they are burden too heavy.
This paper describes a new noninvasive measurement of blood components based on optical sensing. This uses Fourier transform infrared spectroscopy of attenuated total reflection. In order to study, the influence of individual difference, the internal standard method was introduced. This paper describes the detail of the internal standard method and its effect to the blood components calibration. Significant improvement was obtained by using the internal standard.
