Reaction cassette for measuring the concentration of glycated hemoglobin and measuring method thereof

Abstract

A reaction cassette for a glycated hemoglobin meter and a measuring method thereof are provided. The reaction cassette for the glycated hemoglobin meter includes: a first zone receiving a first reagent and a blood sample; a second zone receiving a second reagent; a reaction zone in which the blood sample reacts with the first reagent, or through which the second reagent passes to react with a first blood sample mixture obtained by reacting the blood sample with the first reagent; and a measurement zone measuring an amount of total hemoglobin in the first blood sample mixture, or measuring an amount of glycated hemoglobin in a second blood sample mixture obtained by reacting the first blood sample mixture with the second reagent, wherein the blood sample, the first reagent, and the second reagent move between the reaction zone and the measurement zone according to a rotation angle of the reaction cassette when the reaction cassette is rotated. Therefore, since the reaction cassette reduces the operating time, it is possible to resolve storage and distribution problems of the reaction cassette, which occur when reagents are stored in the reaction cassette.

Problems solved by technology

In this patent, the detection of analytes is periodic and sequential, and the user must participate in the detection process by sequentially injecting test samples so that the test samples react with other substances

Furthermore, the detection process takes a long time since the microspheres bound to HbA1c must be filtered out

[0008] That is, because traditional detection methods require the user's direct involvement in each step, the user may feel inconvenient

Moreover, the direct participation of users makes the detection process more complicated and further prolongs the detection time
