To determine the normal range for hemoglobin A1c, we examine the various ranges provided:
- Less than 12.0%
- Less than 5.7%
- Less than 7.0%
- Less than 8.0%
Hemoglobin A1c is a key indicator used in the medical field to assess the average blood sugar levels over the past two to three months. It is important for diagnosing and monitoring diabetes.
A normal range for hemoglobin A1c is typically regarded as less than 5.7%. This value indicates that your blood sugar levels have been normal over the past few months, and it's used as a benchmark to separate healthy individuals from those at risk of diabetes or those already diagnosed with diabetes.
The other provided ranges (less than 12.0%, less than 7.0%, and less than 8.0%) suggest higher levels of blood sugar, indicating prediabetes, diabetes, or poorly controlled diabetes.
Therefore, the normal range for hemoglobin A1c is less than 5.7%.
