他沒有檢查過你母親的HbA1c level (簡稱A1C test)?
The following are the results when the HbA1c is being used to diagnose diabetes:
- Normal: Less than 5.7%
- Pre-diabetes: 5.7% to 6.4%
- Diabetes: 6.5% or higher
If you have diabetes, you and your doctor or nurse will discuss the correct range for you. For many people the goal is to keep your level at or below 6.5 - 7%.
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results. The examples above show the common measurements for results for these tests. Some laboratories use different measurements or may test different specimens.
