With over 1.5 million years of combined knowledge, the Diabetes Forum is the perfect place to connect with other people who have prediabetes or have placed the condition into remission.
Visit the diabetes ForumHbA1c or glycated haemoglobin is your average blood sugar (glucose) level over a period of time, usually from two to three months.
Your average blood sugar levels are a useful indicator of your risk of developing prediabetes, with higher levels a sign that there is too much sugar in your blood.
Having excess glucose in your bloodstream can cause severe damage to organs and lead to diabetes-related complications such as diabetic retinopathy and neuropathy.
Convert HbA1c Units from DCCT/IFCC and to Average Blood Glucose
Recommended Hba1c Ranges
While everyone will have some sugar in their blood, your HbA1c results should ideally be below 42mmol/mol or 6.0%.
HbA1c results of 42mmol/mol - 47mmol/mol or 6% to 6.4% are diagnostic of prediabetes, with an increased risk of developing type 2 diabetes. While results of 48mmol/mol and over (6.5% and over) are diagnostic of type 2 diabetes.
Result Accuracy
The aim of the above calculator is to provide an estimated HbA1c value from your average blood glues results. However, you should note that the HbA1c and blood glucose tests measure two different things.
Blood glucose tests measure concentrations of glucose molecules in your blood at the moment you take the initial measurement.
On the other hand, the HbA1c test measures the proportion of haemoglobin molecules that have chemically bonded with the glucose in your blood over a period of three months.
This doesn't mean the HbA1c calculator is inaccurate, instead, you can use it as a useful guide on what your HbA1c lab result might be based on your blood glucose results.
