What is the significance of Hemoglobin A1c in hematology?

• A. It measures short-term blood glucose levels
• B. It is used to assess long-term glycemic control in diabetes
• C. It evaluates the bone marrow activity
• D. It indicates hemoglobin levels within red blood cells

Answer: (B)

Hemoglobin A1c is significant in hematology primarily because it is used to assess long-term glycemic control in individuals with diabetes. This measurement reflects the average blood glucose levels over the previous two to three months, providing insights into how well the blood sugar is being managed over an extended period. The primary utility of Hemoglobin A1c lies in its ability to provide a snapshot of overall glucose exposure, which is crucial for understanding the effectiveness of diabetes management strategies. A higher A1c level indicates poorer blood glucose control and a greater risk for diabetes-related complications, such as cardiovascular disease, neuropathy, and retinopathy. The other concepts, such as measuring short-term blood glucose levels, evaluating bone marrow activity, or indicating hemoglobin levels within red blood cells, do not accurately reflect the role of Hemoglobin A1c in clinical practice. Instead, these aspects pertain to other tests or assessments within hematology and endocrinology.
