Glycosylated hemoglobin, is a term that diabetics must know. It is a very important concept. Glycosylated hemoglobin is a response to the average blood sugar level over 2-3 months. It is the gold standard of blood sugar control. Many patients do not understand: if I measure my finger blood glucose, can’t it also indicate the level of my blood glucose? Why do I need to measure glycated hemoglobin? We say: measuring finger blood glucose is a point, while glycosylated hemoglobin is a surface. Through a point, it is impossible to fully reflect the control of blood sugar. A good student can occasionally score 60, and a poor student can occasionally score 80. You cannot judge the merits of a student from this one test alone. If you average the semester’s scores, the scores are still basically indicative of a student’s level. The average score for the semester is the glycosylated hemoglobin. So, glycosylated hemoglobin is the report card of a diabetic, you say your blood sugar is good? No? Showing your doctor your glycemia is the best and most intuitive way to tell. You can judge your blood sugar control as good or bad by the specific value of glycation. How is glycated hemoglobin tested? It is simply a blood draw and does not require fasting. We recommend that patients have their glycemia tested every 3 months or so, and a glycemia of <6.5 can be rated as a "100" for blood glucose control.
