HbA1c Blood Test – Price, Purpose, Normal Range, Preparation
The HbA1c test, also known as the glycated hemoglobin test, measures your average blood sugar levels over the past two to three months. This simple blood test helps diagnose diabetes and pre-diabetes and is crucial in monitoring long-term glucose control for individuals already diagnosed with diabetes. It is an essential test that helps doctors assess how well a person’s blood sugar has been managed, providing valuable insights into their overall health. The HbA1c test price in India ranges from Rs 300 to Rs 600, However, the actual price depends on the diagnostic center and the city.
What is the HbA1c Blood Test?
The HbA1c blood test measures the percentage of hemoglobin in the blood that is bound to sugar. Hemoglobin is a protein in red blood cells that carries oxygen throughout the body. Since red blood cells have a lifespan of about three months, the HbA1c test provides an average of blood glucose levels over that period. This test is commonly used to diagnose diabetes and monitor the effectiveness of diabetes management.

When is it recommended to get tested?
The HbA1c test is required if a person has one or more symptoms of diabetes. These include:
- Enhanced thirst/hunger: The patient feels the urge to eat more. Diabetes decreases muscle glucose uptake due to low insulin levels. Therefore, the muscles and other tissues indicate a “hunger” message to get more energy.
- Increased urination: This is due to the increased burden on the kidneys to filter and absorb the excess glucose from the body fluid.
- Blurred vision: The high blood sugar level causes the eye’s lens to swell and impairs clear vision.
- Unexplained fatigue: Instead of getting converted into energy, the glucose remains flowing in blood circulation. This unavailability of energy causes fatigue.
- When cuts or wounds take longer than usual to heal: Poor blood circulation slows down blood making it more difficult for the body to deliver nutrients to cuts or wounds.
- Tingling, numbness in the hands/feet (type-2): The nerve damage in the limbs causes the tingling sensation in the patients.
Who should get Hba1c tested?
A doctor recommends the HbA1c test if a person is at high risk of diabetes. The risk factors are:
- Being overweight or obese (BMI>25): An fat person is at high risk to have an imbalance of HbA1c.
- High blood pressure: High blood pressure is a contributing factor to diabetes. It should be well regulated.
- History of heart disease: Heart disease patients should undergo HbA1c testing.
- Family history of diabetes: Those persons who have some diabetic family members need to consult HbA1c testing.
- Physical inactivity: Persons doing a sitting job should regularly check their HbA1c levels.
- Women over 45 years: As women grow older, they develop low haemoglobin levels.
- Women with a history of polycystic ovary syndrome (PCOS): The PCOS ovary syndrome may cause low haemoglobin levels.
Due to its importance in diabetes diagnosis, it is often included in diabetes checkup tests.
When to go for the HbA1C Test?
The following conditions during which the patient should take the HbA1C test after consulting with the doctor.
- During diabetes: Doctors recommend an HbA1c test for people with type 1 (Insufficient insulin production by the pancreas) and type 2 (problem with glucose processing) diabetes. During other medical conditions, Doctors recommend Blood sugar and HbA1c to ensure that blood sugar is within the permissible range and under control.
- During pregnancy: Many women have the problem of gestational diabetes. Though it is temporary and affects only during the pregnancy, it negatively affects health. Pregnant women should do this test to ensure a safe and healthy pregnancy. It is one of the essential tests during pregnancy.
Why should you try to lower your HbA1c levels?
Studies show that improving HbA1c by 1% (or 11 mmol/mol) for people with type 1 or type 2 cuts the risk of microvascular complications by 25%. Microvascular complications include:
- Retinopathy: This refers to damage to the retina of the eye of the patient.
- Neuropathy: It means the damage to the nerves arising out of the brain of the patients.
- Diabetic nephropathy: This condition indicates the damage of blood vessels in the kidney due to nephropathy.
HbA1c Test Schedule
A patient should undergo an HbA1c test every three to six months, depending on their treatment and level of control of diabetes. One should measure the HbA1c level at the time of diagnosis and initiation of therapy.
After that, it should be done at least twice a year in people with type II diabetes who do not use insulin. It is better to do it four times a year for insulin-dependent (type I) diabetes or for type II diabetes who use insulin.
Timings of HbA1c test
Doctors recommend this test at least twice a year for diabetic patients. Usually, doctors also recommend this test before any major medical procedure. As the Red blood cells live for about three months, the test shows the average glucose level in your blood for the last three months. For a diabetic patient, the doctor recommends having the test done every 3-6 months as it indicates the overall control of blood glucose levels over the previous 8-12 weeks.
Procedure
The HbA1c is a simple blood test that can be taken by your doctor or at a pathology lab. The steps of the procedure are as follows:
- The technician will rub the alcohol on the area of the skin and will take a syringe.
- The blood veins would be needle pricked.
- The technician would utilise a syringe for blood withdrawal.
- Collect the blood sample into a test tube or vial.
- You may feel a slight sting when the needle goes in or out.
Preparation
HbA1c test does not require fasting or any other special preparation. A patient need not fast before the test, and you can eat and drink as normal.
HbA1c test Result
The HbA1c test results indicate average blood glucose over the past three months. Its results are indicative of diabetes. However, your doctor may recommend other tests like blood sugar fasting or PP and Insulin test and clinical observations to confirm diabetes.
The results should be available within 24 hours. Some labs may report average blood glucose in their HbA1c report.
Is the HbA1c test always reliable?
Following are the conditions that may give fall results:
- False-positive/negative due to genetic disorder: Most of us have type A haemoglobin (HbA, or adult haemoglobin), but some people have a variant form of haemoglobin. This is known as haemoglobinopathy, and it can also cause falsely high or low HbA1c results.
- False positives due to underlying medical conditions: Iron deficiency, anaemia, haemolytic anaemia, blood loss, chronic (ongoing) liver disease, chronic kidney disease or any other type of blood disorder can falsely give positive results.
HbA1c test Normal range
Following are the values indicating the stages of diabetes based on the HbA1c test results.
| Normal | Pre Diabetes | Diabetes |
|---|---|---|
| 3.5% to 6% (15 to 42 mmol/mol) | 6% to 6.4% (42 to 47 mmol/mol) | 6.5% (48 mmol/mol) or more |
A normal HbA1c level is below 6%. The normal range does not vary with age. The table below lists the normal ranges with qualitative categorisation.
| Indication | Normal Range |
|---|---|
| Normal Value | Below 6% |
| Good Control | 6%-7% |
| Fair Control | 7%-8% |
| Unsatisfactory Control | 8%-10% |
| Poor Control | Above 10% |
The result can be used to calculate the average blood glucose. It indicates the Average Blood Sugar level over the past three months. However, all the labs do not report average blood glucose in their HbA1c report. The table below lists its normal range of average blood glucose level.
| Indication | Values in mg/dl |
|---|---|
| Excellent Control | 90-120 mg/dl |
| Good Control | 121-150 mg/dl |
| Average Control | 151-180 mg/dl |
| Need Action | 181-210 mg/dl |
| Panic Value | Above 211 mg/dl |

Frequently asked questions
This test is not suitable for gestational diabetes. Gestational diabetes affects pregnant women.
Iron, Vitamin B12, C, E and folate supplements; high cholesterol levels, Erythropoietin therapy(to treat anaemia); Aspirin treatment; and certain antiviral and antimicrobial medicines in the blood can affect the result of the test.
Most doctors recommend taking the HbA1c test every three to six months if you have diabetes or prediabetes. This helps monitor long-term blood sugar control.
No fasting is required for an HbA1c test. You can take it at any time of the day, as it measures your average blood sugar over the past three months.
A healthy HbA1c level is usually below 5.7%. Levels between 5.7% and 6.4% indicate prediabetes, while 6.5% or higher may suggest diabetes.
The HbA1c test is mainly used to diagnose type 2 diabetes and monitor it. It may not always detect type 1 diabetes or gestational diabetes accurately.
No, the HbA1c test isn’t typically used for gestational diabetes. Instead, an oral glucose tolerance test is preferred for detecting diabetes during pregnancy.
