Which of the following is a normal range for hemoglobin A1c?

A. Less than 12.0%
B. Less than 5.7%
C. Less than 7.0%
D. Less than 8.0%



Answer :

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%.
