Method for immunological determination of hemoglobin derivative and treating reagent for use therein

摘要

A hemoglobin derivative-containing sample is treated with a treating reagent containing 2-butanol and then immunologically analyzed to determine the quantity of the hemoglobin derivative. By the treatment with 2-butanol, the immunological determination for the hemoglobin derivative, particularly HbA1c, can be attained with high sensitivity by a simple procedure. Since 2-butanol-containing treating reagent does not affect the enzymatic activity, the homogeneous enzyme immunoassay with high sensitivity is realized.
