Introduction
Glycation usually refers to glycated hemoglobin (HbA1c). Under normal circumstances, both glycated hemoglobin and blood glucose are important indicators for assessing diabetes control. However, they reflect blood glucose levels over different time periods, and therefore each has its own advantages. It cannot be simply stated that one is more accurate than the other. To avoid misdiagnosis or improper treatment, it is recommended to use both indicators together under the guidance of a physician.
Glycation usually refers to glycated hemoglobin. Under normal circumstances, both glycated hemoglobin and blood glucose are important indicators for assessing diabetes control. However, they reflect blood glucose levels over different time frames, so each has its own advantages, and it cannot be simply stated that one is more accurate than the other. Detailed analysis is as follows:
Blood glucose refers to the concentration of glucose in the blood, which can be rapidly measured using devices like glucometers, reflecting the current blood glucose level. Therefore, when evaluating blood glucose status within the current time frame, blood glucose measurement is more accurate. Glycated hemoglobin refers to the concentration of glycated hemoglobin formed by the combination of hemoglobin and glucose, reflecting the average blood glucose level over the past 2–3 months. When assessing long-term blood glucose control in diabetic patients, glycated hemoglobin is more accurate.
To avoid misdiagnosis or improper treatment, it is recommended to use both indicators in combination under a doctor's guidance. Glycated hemoglobin is used for long-term monitoring, while blood glucose is used for daily management. At the same time, attention should be paid to lifestyle habits to optimize blood glucose control.
