What is HbA1c?
The HbA1c test measures the percentage of hemoglobin proteins in your blood that are coated with sugar (glycated). It provides an average of your blood glucose levels over the past two to three months, making it a key test for diagnosing and monitoring diabetes.
Purpose of the Test
- Diagnose type 1 and type 2 diabetes
- Monitor long-term blood sugar control
- Adjust diabetes treatment plans
- Assess risk of diabetes complications
Preparation
- No fasting is required for this test.
- Continue taking your regular medications unless told otherwise.
- Avoid scheduling the test if you are ill, as illness can temporarily affect results.
Procedure
- A blood sample is collected from a vein in your arm.
- The process usually takes less than 5 minutes.
- Results are typically available within 24 hours.
Result Interpretation
- Normal: Below 5.7%
- Prediabetes: 5.7%–6.4%
- Diabetes: 6.5% or higher
Target HbA1c levels for diabetic patients are often below 7%, but may vary depending on individual health conditions.

FAQs
- How often should HbA1c be tested? At least twice a year for well-controlled diabetes; more often if treatment changes.
