What is the HbA1c Test?

HbA1c measures glycated haemoglobin and provides an estimate of average blood glucose exposure over roughly the previous two to three months. It is commonly used for diabetes assessment and for monitoring longer-term glucose control. Results are interpreted in the context of the person’s health and other investigations.

HbA1c Test normal range

HbA1c can read falsely high or low with anaemia, haemoglobin variants such as thalassaemia trait, recent blood loss or transfusion, pregnancy and advanced kidney disease. In those cases doctors rely more on glucose readings.

Ranges differ between laboratories and methods. The reference range printed on your own report is the one to read your result against.

What your HbA1c Test result means

High

5.7–6.4% suggests prediabetes and 6.5% or more meets the criterion for diabetes. In someone already treated, a rising HbA1c means sugar has been higher on average over recent months.

Low

A value below the normal range is unusual. It can follow blood loss, haemolysis or a transfusion, or reflect frequent low sugars in someone on diabetes medicine.

One result is not a diagnosis. A doctor reads it with your symptoms, history, medicines and other tests.

HbA1c Test levels: what does my number mean?

HbA1c 5.4%

Normal. Below 5.7% is the non-diabetic range; 5.4% corresponds to an average blood sugar of about 108 mg/dL over the last two to three months.

HbA1c 5.7% to 6.4%

The prediabetes range. Blood sugar is higher than normal but below the diabetes cut-off. Weight loss, activity and diet changes lower the risk of progressing; the test is usually repeated every year. Often checked next: FBS Test.

HbA1c 6.5%

6.5% or higher is the cut-off for diabetes. Without clear symptoms or a very high sugar reading, the diagnosis is confirmed by repeating HbA1c or doing a fasting sugar test. 6.5% equals an average sugar of about 140 mg/dL. Often checked next: FBS Test.

HbA1c 7%

The usual target for many adults with diabetes is below 7%, which is an average sugar of about 154 mg/dL. Targets are set individually; older adults or people prone to low sugars often have a higher one.

HbA1c 7.6% to 8%

Above the usual target. 8% is an average sugar of about 183 mg/dL. Doctors usually review diet, activity and medicines, and recheck HbA1c after three months. Often checked next: PPBS Test.

HbA1c 9% to 10% or higher

Well above target: 9% is an average sugar of about 212 mg/dL and 10% about 240 mg/dL. Sugar this high over months raises the risk of kidney, eye and nerve damage, and needs a doctor's review of treatment soon. Often checked next: RFT Test.

Typical adult cut-offs. Read your number against the range printed on your own report, and with a doctor if it is outside it.

Why is the HbA1c Test done?

• Diagnosing diabetes and prediabetes
• Checking long-term control every 3 to 6 months in people with diabetes
• Deciding whether treatment needs to change
• Screening adults with risk factors such as obesity or a family history
