Measurement Principle

Measurement Principle


Red blood cells in the sample are hemolyzed. Hemoglobin is oxidized to form met-hemoglobin.

First Reaction

Fructosyl dipeptide (fructosyl-VH) is cleaved at the N-terminus of hemoglobin β-chain by the action of protease.
Met-hemoglobin is converted into azido met-hemoglobin by the action of sodium azide. Absorbance of the product is measured to determine the hemoglobin concentration.

Second Reaction

Reaction between fructosyl dipeptide (fructosyl-VH) and fructosyl peptide oxidase (FPOX) produces hydrogen peroxide, which reacts with the coloring agent to form color in the presence of peroxidase. Absorbance of the colored substance is measured to determine the HbA1c concentration.

Calculation formula for HbA1c (%)

HbA1c(NGSP %) = 91.5 × HbA1c
(μmol/L) / Hb (μmol/L) + 2.15
