RED BLOOD CELL GLYCATION MEASUREMENT USING MECHANICAL AND ELECTRICAL CHARACTERISTICS, AND METHOD FOR MEASURING VALUES OF GLYCATED HEMOGLOBIN BY USING SAME AND APPARATUS FOR PERFORMING SAME

Document Type and Number:

WIPO Patent Application WO/2023/054810

Kind Code:

A1

Abstract:

The present invention relates to a method for measuring the concentration of glycated hemoglobin A1c. An apparatus for measuring glycated hemoglobin according to the present invention comprises: an inlet through which collected blood flows; a microchannel having a predetermined width so that red blood cells in the blood having flowed in through the inlet pass through as individual units; an outlet through which the red blood cells having passed through the microchannel are discharged; and a plurality of electrode units formed to be in contact with the microchannel between the inlet and the outlet, wherein the electrode units comprise a plurality of electrodes arranged in a predetermined space along the direction of the passage of red blood cells passing through the microchannel. According to the present invention, the degree of hardness of glycated red blood cells can be more easily determined without chemical measurement equipment by calculating the time of passing through the microchannel.
