Glycated hemoglobin (or HbA1c) reflects blood sugar. While capillary blood glucose and fasting blood glucose are snapshots of glycemic status, HbA1c allows, through a blood test, to assess glycemic control over a longer period (about two to three months).
Associated with reading and interpreting the results of your monitoring diary, HbA1c is a marker of the risk of complications from your diabetes in the long term.
formula: Average Blood Glucose = HbA1c (in %) x 1.59 - 2.59.
| HbA1c value | Average blood sugar |
| 6% | 1.2g/l |
| 7% | 1.5g/l |
| 8% | 1.8g/l |
| 9% | 2.10g/l |
| 10% | 2.40g/l |
A blood sugar of 7% corresponds to an average blood sugar of 1.5g/l.
1% more HbA1c represents an average increase in blood sugar of 0.30g/l.
