Glucose is called blood glucose in the human body. The difference between blood glucose and glycosylated hemoglobin is that blood glucose reflects the current level of glucose in the blood, while glycosylated hemoglobin responds to the average level of glucose in the blood over the past 2 to 3 months.
Glycated hemoglobin (HbA1c) is the product of the non-enzymatic reaction between hemoglobin in red blood cells and sugars in serum, which can reflect the level of glycemic control in the last 2-3 months, but does not reflect the instantaneous level of glucose and the fluctuation of glucose throughout the entire blood sugar, blood glucose can reflect the instantaneous situation of blood glucose, and both of them have been included in the diagnostic criteria for diabetes mellitus.
Patients with the typical “three more and one less” symptoms of diabetes can be diagnosed with diabetes if they meet any one of the following criteria: fasting blood glucose of 7 ≥ mmol/l, or 2-hour postprandial blood glucose of ≥ 11.1 mmol/l, or random blood glucose of ≥ 11.1 mmol/l, or glycosylated hemoglobin of ≥ 6.5%.
If there are no symptoms of diabetes, two plasma glucose events meeting these criteria are required to confirm the diagnosis.
If blood glucose or glycosylated hemoglobin is abnormal, please consult a doctor for further treatment.
