  • Method of measuring stable A1c
    Patent number: 11385244
    Abstract: A method of measuring stable A1c in a blood sample based on a time distribution of an optical measured value of hemoglobin at a flow path which separates hemoglobin in the blood sample on a basis of amounts of the charges of hemoglobin is provided. The method may include a step of obtaining a correction factor, based on a peak area (A) of a fraction including HbA0 and either a peak area (G) of a first fraction including chemically-modified HbA0, or a peak area (D) of a second fraction including a component having a smaller amount of positive charge than HbA0 adjacent to a fraction identified as HbA0, in the time distribution; and a step of correcting, based on the correction factor a peak area of a fraction including stable A1c in the time distribution.
