  • Separable cassette for measuring glycated hemoglobin
    Patent number: 11474120
    Abstract: The present invention relates to a separable cassette for measuring glycated hemoglobin. It is easy to use the separable cassette for measuring glycated hemoglobin of the present invention since a reagent is sequentially leaked during the rotation thereof. In addition, there is no need to shake the reagent beforehand, as the reagent without residual reagent is fully discharged by the rotation. Therefore, the measurement result is accurate because an error between the amount of the reagent used and the amount of sample blood is small.
