What could a hemoglobin A1C of 7% indicate in a patient?

• A. Pre-diabetes
• B. Normal glucose levels
• C. Diabetes mellitus
• D. Hypoglycemia

Answer: (C)

A hemoglobin A1C level of 7% indicates that an individual has diabetes mellitus. This test measures the average blood glucose levels over the past two to three months, providing a clear picture of long-term glucose control. The American Diabetes Association defines diabetes as having an A1C of 6.5% or higher. Therefore, a result of 7% confirms the diagnosis of diabetes, requiring further monitoring and management to manage blood sugar levels effectively. In contrast, a level below 5.7% is considered normal, while 5.7% to 6.4% is diagnostic for pre-diabetes. Hypoglycemia refers to low blood sugar levels, which would not be indicated by an A1C test that shows sustained elevated glucose levels. Thus, a 7% A1C level clearly confirms the presence of diabetes rather than indicating any of these other conditions.
