This tool converts your HbA1c result into an estimated average glucose (eAG) using the equation from the ADAG study, helping you relate a lab percentage to everyday glucose-meter numbers.
Sample input: HbA1c (%): 7
Estimated average glucose: 154 (Diabetes range (8.6 mmol/L))
An A1c of 7% corresponds to an estimated average glucose of about 154 mg/dL (8.6 mmol/L), using the ADAG study equation. This falls in the diabetes range per ADA criteria. Discuss with your doctor.
HbA1c reflects your average blood glucose over the past 2 to 3 months by measuring the percentage of haemoglobin that is glycated. It is a standard test for diagnosing and monitoring diabetes.
We use the ADAG study equation (Nathan et al., Diabetes Care 2008): estimated average glucose in mg/dL equals 28.7 times A1c minus 46.7. We also show the value in mmol/L.
Per American Diabetes Association criteria, an A1c below 5.7 percent is normal, 5.7 to 6.4 percent indicates prediabetes, and 6.5 percent or higher indicates diabetes. Diagnosis should be confirmed by a clinician.
No. This is an educational estimate of average glucose. Interpret your A1c and any treatment changes with your healthcare provider, who can consider your full clinical picture.
