What Is the HbA1c Test?
The HbA1c Test is a critical diagnostic screen performed to evaluate key biomarkers in your blood. Regular testing plays a vital role in the early detection and management of health issues, ensuring you can take proactive control of your wellbeing.

|---|---|---|
| HbA1c (Glycated Hemoglobin) | Percentage of hemoglobin coated with glucose | Less than 5.7% |
| Estimated Average Glucose (eAG) | Average daily blood sugar level calculated from HbA1c percentage | Less than 117 mg/dL |
How to Prepare for the HbA1c Test
Preparing for your home blood test is fast and easy:
- Fasting: Fasting is generally not required for this test.
- Hydration: Drink plenty of plain water before your slot. Staying hydrated helps the phlebotomist locate veins easily.
- Medications: Consult your doctor on whether you should pause any daily supplements or prescription drugs before the test.

What does the HbA1c test show?
The HbA1c test measures the percentage of blood hemoglobin that is coated with sugar. Because red blood cells live for about 3 months, this test provides a reliable estimate of your average blood glucose control over the past 90 days.
Is fasting required for an HbA1c test?
No, fasting is not required for a standalone HbA1c test. You can eat and drink normally before your sample is collected. However, if you are also taking a Fasting Blood Sugar test, you must fast for 8-10 hours.
How much does an HbA1c test cost at home?
An HbA1c blood test with free home sample collection starts from ₹ 299. The package includes certified laboratory testing and digital report delivery.
What is a dangerous HbA1c level?
An HbA1c level of 6.5% or higher indicates diabetes. Levels above 8% mean your blood sugar is poorly controlled, and levels above 10% indicate a severe, dangerous elevation requiring immediate medical attention.
Can HbA1c levels fluctuate quickly?
No. Because HbA1c reflects average sugar levels over 2-3 months, daily fluctuations in food, stress, or exercise do not significantly alter the result. It changes gradually as new red blood cells are formed.
