Testing Methods for Diabetes
Self-monitoring diabetes at home
A1C
A1C (hemoglobin A1C) can be used to diagnose diabetes by measuring the amount of glucose attached to hemoglobin. This test helps detect prediabetes early, allowing for timely intervention. It is recommended to test at least twice per year.
The A1C [%] levels correspond to different stages of blood sugar control, as shown in the chart. From this, the higher the levels, the greater your risk of developing diabetes complications.
After that, A1C provides the estimated average glucose [eAG - mg/dL (mmol/L)] over the past 2~3 months that is based on the A1C results, helping patients know their situations and develop treatment earlier.
-
Below 5.7%, it represents the normal blood sugar level.
The A1C [%] levels correspond to different stages of blood sugar control, as shown in the chart. From this, the higher the levels, the greater your risk of developing diabetes complications. -
Between 5.7%~6.5%, it shows the blood sugar levels are in the prediabetes range.
-
Reach or higher than 6.5% --> you are in the diabetes range
-
Less than 7% is the better number for most adults with diabetes. But your goal target would also change as your life style and age changed. Please discuss with your doctor!
-
For elders, A1C ≥ 6.5 & fasting blood glucose ≥ 126 mg/dL are the best!
