Also called: Glycated haemoglobin, A1c
What is it?
HbA1c shows how much sugar has stuck to your haemoglobin over about 8 to 12 weeks. It is used to find diabetes and to see how well diabetes is controlled.

Usual numbers
| Measure | Typical adult range |
|---|---|
| Normal | below 5.7 % |
| Pre-diabetes range | 5.7 % to 6.4 % |
| Diabetes range | 6.5 % or higher (a doctor confirms with repeat testing) |
Ranges are typical values used in India. Every lab prints its own range on your report, and that range is the one to follow. A number outside the range does not always mean disease. Your doctor decides what it means for you.
