Abstract
When the concentration of glycated hemoglobin is measured, a plurality of wavelengths are selected as measurement wavelengths from the wavelength range of 400 to 450 nm. Preferably, by use of a liquid chromatography, at least the light of different peak wavelengths in the wavelength range of 415 to 430 nm are continuously or intermittently received to obtain a three dimensional chromatogram having as variables the wavelength, the elution time and the amount of detection. The concentration of glycated hemoglobin is calculated based on this three dimensional chromatogram.
