HbA1c normal range: what your 3-month sugar average means
HbA1c is a simple blood test that shows your average blood sugar over the last 2–3 months. Sugar in the blood sticks to haemoglobin in red blood cells, and the test measures how much of it is coated with sugar. Unlike a single sugar reading, it is not affected much by what you ate yesterday. Doctors use it to check for prediabetes and diabetes and to see how well sugar is controlled in people who already have diabetes. It needs no fasting.

What does my result mean?
HbA1c 5.8%
This falls in the prediabetes range, just above normal. It is a useful early warning; discuss diet, activity and a repeat test with your doctor.
HbA1c 6.2%
This is in the prediabetes range. It does not mean diabetes, but the risk is higher, so ask your doctor about next steps and when to recheck.
HbA1c 7%
This is above the cut-off for diabetes. Only a doctor can confirm diabetes, usually with a repeat test or another sugar test, and plan care.
What this test checks
HbA1c measures the percentage of haemoglobin that has sugar attached to it. Adults with a family history of diabetes, extra weight, high blood pressure or past high sugar in pregnancy are often advised to check it. People with diabetes usually test every 3–6 months, as advised by their doctor. Others may check it once a year or as the doctor suggests.
Common reasons for a high value
Prediabetes or diabetes
Diabetes that is not well controlled
Extra body weight and very little physical activity
Iron deficiency anaemia can give a falsely high reading
Some medicines, such as long-term steroids, can raise sugar
Common reasons for a low value
Healthy sugar levels (low-normal is usually fine)
Recent heavy blood loss or a blood transfusion
Conditions where red cells break down faster, such as haemolysis
Some haemoglobin variants, like thalassaemia, can affect the result
Frequent low sugar episodes in people on diabetes medicines
How to prepare
HbA1c needs no fasting – you can give the sample at any time of day. If your package also includes fasting sugar or a lipid profile, fast 10–12 hours overnight (plain water is fine).
When to see a doctor
See a doctor if your HbA1c is 5.7% or above, or if you have heavy thirst, frequent urination, weight loss without trying or slow-healing wounds. People with diabetes should share every report with their doctor. Confusion, drowsiness, vomiting or fast breathing in someone with very high sugar needs urgent hospital care.
No. HbA1c shows your average sugar over about 3 months, so a meal before the test does not change it much. You can give the sample at any time of day.
Is HbA1c 6% normal?
An HbA1c of 6% is in the prediabetes range (5.7–6.4%). It is not diabetes, but it is a sign to improve diet and activity. Your doctor will tell you when to repeat the test.
Can HbA1c be wrong?
It is a reliable test, but anaemia, recent blood loss, a transfusion or some haemoglobin variants such as thalassaemia can affect it. Your doctor may then use fasting or post-meal sugar tests along with it.
How is the HbA1c sample collected?
A trained phlebotomist collects a small blood sample at your home. It is tested at a Thyrocare partner lab and the report is sent to you on WhatsApp and email.

HBA Profile assesses long-term blood sugar levels and helps with glucose management. It includes Hemoglobin A1c (HbA1c) test, which measures the average blood sugar levels over the past 2-3 months for diagnosing and monitoring diabetes or prediabetes and calculates the Average Blood Glucose (ABG) level. The profile helps patients monitor diabetes and effectively evaluate treatment. No fasting needed.
HbA1c test, also known as glycated hemoglobin test, measures average blood glucose levels. It provides an overview of long-term blood sugar control, essential for diagnosing and managing diabetes. Regular monitoring of HbA1c levels is key to reducing the risk of complications and maintaining optimal health for individuals with diabetes.
