Hemoglobin A1c Test (HbA1c)
Hemoglobin A1c Test (HbA1c) is a laboratory test that reflects the average blood glucose level over the past 2-3 months. This test is widely used for diagnosing and monitoring diabetes mellitus.
What the HbA1c test shows:
- The percentage of hemoglobin bound to glucose (glycated hemoglobin).
- The average blood sugar level over a long period, helping to assess treatment effectiveness and risk of complications.
Advantages of the test:
- Does not require fasting.
- Reflects long-term glycemic control, unlike the standard blood glucose test.
- Used for diagnosing diabetes and prediabetes.
Interpretation of results:
- Normal: less than 5.7% (39 mmol/mol).
- Prediabetes: 5.7%–6.4% (39–46 mmol/mol).
- Diabetes: 6.5% (48 mmol/mol) and above.
Indications for testing:
- Diagnosis of diabetes mellitus.
- Monitoring diabetes treatment effectiveness.
- Assessing risk of developing complications.
The HbA1c test is an important tool for doctors and patients, allowing control over disease progression and therapy adjustment.
