HbA1c (Glycated Hemoglobin)
Reflects average blood sugar over the past 2–3 months. The gold standard for diabetes monitoring.
Typical normal range
< 5.7% (normal) · 5.7–6.4% (prediabetes) %
If high ↑
Diabetes (≥ 6.5%), poor glycemic control, increased complication risk
If low ↓
Excellent glycemic control; below 4% may indicate hemolytic anemia
What is a normal HbA1c level?
A typical reference range is < 5.7% (normal) · 5.7–6.4% (prediabetes) %. Ranges vary between laboratories and can depend on age and sex, so compare your result with the range printed on your own report.
What does a high HbA1c level mean?
Diabetes (≥ 6.5%), poor glycemic control, increased complication risk. A single result rarely gives a diagnosis on its own; your doctor will interpret it alongside your symptoms and other tests.
What does a low HbA1c level mean?
Excellent glycemic control; below 4% may indicate hemolytic anemia. Your doctor will interpret it alongside your symptoms and other tests.
