HbA1c

Also known as: Glycated Hemoglobin, Glycosylated Hemoglobin, A1c

Diabetes & Hormones Blood (no fasting needed)
Patient Friendly Summary

Think of HbA1c as your sugar report card for the whole term, not just one exam. You cannot change it by being careful for two days before the test — it reflects months of control.

What this test means

HbA1c measures how much sugar has stuck to your red blood cells, reflecting average sugar control over about three months — not just today.

Why it is done

It is done to diagnose diabetes, monitor long-term control, and guide treatment adjustments every 3–6 months.

Understanding your value

If your value is high

6.5% or more can suggest diabetes; 5.7–6.4% may suggest prediabetes. In known diabetes, higher values mean control needs improvement.

If your value is low

Unusually low values in someone on diabetes treatment may suggest frequent low sugars and should be discussed with the doctor.

About the normal range

Below 5.7% is commonly considered normal. Many doctors target below 7% for people with diabetes, individualized to age and health.

When to consult a doctor

Review every HbA1c result with your doctor to fine-tune diet, activity, and treatment. Rising trends deserve early attention.
