Abstract

A blood analyzer for measuring blood hemoglobin concentrations serving as indications in diagnosing diabetes or controlling blood glucose level. From characteristic curves showing the molar absorption coefficient ratios of three hemoglobin components including HbAlc-O2, Hb-O2 and Hb-CO, the wavelength at which the absorbance ratio of each component attains a peak or the wavelength at which the absorbance ratio of each component attains the maximum level is selected. Then the composition ratio of the hemoglobin components is calculated based on the molar absorption coefficients of the hemoglobin components at these wavelengths and the absorbances of a biological tissue at these wavelengths. Thus, the concentrations of the hemoglobin components are indicated non-invasively.
