The hemoglobin A1C result is an important value for long-term glucose monitoring; about three, months mean value of glucose level. HbA1C results are in percentage value. This percentage (%) value may be confusing for many. It is because, we are practicing measuring our plasma glucose levels in mg/dl or mmol/l using a glucose monitor. Here, you can learn how to get more information from your HbA1C test results.
To convert the A1C to average plasma glucose value; let us consider the higher end of the normal range of A1C as 6%, which is equal to the higher end of the normal average glucose of 120 mg/dl. For every 1% A1C change, there is a similar change (increase or decrease) of about 35 mg/dl (or 2 mmol/l) of average plasma glucose.

For non-diabetes, the normal hemoglobin A1c range is between 4% and 5.6%. A1c range of 5.7% to 6.4% indicates increased risk towards diabetes, and levels of 6.5% or higher suggests diabetes.
Many people have a question, what does it mean if I have a high A1C and normal blood sugars? Many others, on the other hand, have a question, what does it means if I have normal A1C and high fasting glucose? If you are one among them visit A1C glucose level relationship.
