A chart of HbA1c levels is available to download from Diabetes.co.uk. HbA1c is glycated hemoglobin and is an indicator of diabetes control. HbA1c levels provide a picture of what the average blood sugar levels have been over the past few weeks or months.
For non-diabetics, the HbA1c target is 4 to 5.9 percent. For diabetics, the target HbA1c is 6.5 percent. For diabetics who are at risk of low blood sugar levels, the target HbA1c is 7.5 percent. HbA1c levels above 7.5 percent indicate poor diabetes control and increased risk of diabetes complications such as eye and kidney disease, according to Diabetes.co.uk. A reduction of HbA1c by 1 percent decreases the risk of amputation due to peripheral vascular disease by 43 percent.
