Why HbA1c Is the Gold Standard for Diabetes

5 min read·28 April 2026

HbA1c (glycated haemoglobin) shows your average blood sugar over the past 2–3 months in a single blood test — no fasting needed. That's why doctors trust it for diagnosing and monitoring diabetes.

Why one snapshot isn't enough

A fasting sugar reading only captures one moment. HbA1c smooths out daily ups and downs, giving a truer picture of long-term control.

Who should test?

  • Adults over 40, or younger with a family history of diabetes.
  • Anyone overweight, with high blood pressure, or PCOS.
  • People with symptoms like excessive thirst, frequent urination or fatigue.

Prevention matters

Early detection lets you act with diet, activity and, if needed, medication before complications develop. Pair HbA1c with a lipid profile for a fuller heart-health picture.

This is general guidance, not medical advice. Discuss results with your doctor.

Frequently asked questions

What is a normal HbA1c?

Generally, below 5.7% is normal, 5.7–6.4% is prediabetes and 6.5% or above suggests diabetes — but always confirm with your doctor.

Do I need to fast for HbA1c?

No. HbA1c does not require fasting because it reflects your average sugar over ~3 months, not a single moment.

How often should diabetics test HbA1c?

Typically every 3 months if control is changing, or every 6 months if stable — as advised by your doctor.
