Final answer:
The A1C value for a controlled diabetic range is less than 7%, indicating good blood glucose control. Diabetics with A1C levels close to 7% have a better chance of preventing complications. Higher levels, such as above 9% or 12%, indicate poor control and may require a change in treatment.
Step-by-step explanation:
The A1C value for a controlled diabetic range is less than 7%. This value reflects the average blood glucose level over the past 4 months.
Diabetics who keep their A1C levels close to 7% have a much better chance of delaying or preventing complications. Higher levels, such as above 9% or 12%, indicate poor control and may require a change in treatment. Lowering the A1C level improves a person's chances of staying healthy.
A 1% change in an A1C result reflects a change of about 30 mg/dl (1.67 mmol/L) in average blood glucose. For instance, an A1C of 6% corresponds to an average glucose of 135 mg/dl (7.5 mmol/L), while an A1C of 9% corresponds to an average glucose of 240 mg/dL (13.5 mmol/L).
