  • Method for measuring glycated hemoglobin and device for measuring glycated hemoglobin
    Patent number: 11555807
    Abstract: A method for measuring a proportion of sA1c (%), which includes, when a peak derived from abnormal hemoglobin D, abnormal hemoglobin S or abnormal hemoglobin C is identified, calculation of the peak area, and measurement of the proportion of sA1c (%) corrected by using the calculation results. Results of measurement are obtained, by cation exchange chromatography, of sA1c (%) with a subject who provided a blood sample containing abnormal hemoglobin D, abnormal hemoglobin S or abnormal hemoglobin C by eliminating influences by such abnormal hemoglobin.

  • METHOD FOR MEASURING GLYCATED HEMOGLOBIN AND DEVICE FOR MEASURING GLYCATED HEMOGLOBIN
    Publication number: 20190120803
    Abstract: The objective is to obtain results of measurement, by cation exchange chromatography, of sA1c reflecting symptoms of a subject who provided a blood sample containing abnormal hemoglobin D, abnormal hemoglobin S or abnormal hemoglobin C by eliminating influences by such abnormal hemoglobin. The above objective is achieved by a method for measuring the proportion of sA1c (%), which comprises, when a peak derived from abnormal hemoglobin D, abnormal hemoglobin S or abnormal hemoglobin C is identified, calculation of the peak area, and measurement of the proportion of sA1c (%) corrected by using the calculation results.
