Method of measuring glycated hemoglobin concentration

摘要

The present invention relates to a method and an apparatus that measure the concentration of glycated hemoglobin by an optical technique. A wavelength in which the molecular extinction coefficient of oxyhemoglobin agrees or substantially agrees with the molecular extinction coefficient of deoxyhemoglobin is adopted as a measurement wavelength. Preferably, the measurement wavelength is set at from 417 to 421 nm. In the present invention, the concentration of glycated hemoglobin is measured by making use of column chromatography and of using a sample prepared from red blood cells in blood.
