How does this tool work?
HbA1c reflects your average blood glucose over about two to three months. This tool uses a well-known formula that estimates the average glucose (eAG) from the HbA1c percentage, and shows it in the two common units: mg/dL and mmol/L.
The result is an estimate and may differ slightly from your daily meter readings. Do not use it to diagnose or to change a medication dose, as your doctor interprets HbA1c and decides your plan. To learn more, read the Sihtak article on reading your HbA1c test.
Frequently asked questions
What does an HbA1c of 7% mean?
An HbA1c of 7% corresponds to an estimated average glucose of about 154 mg/dL (8.6 mmol/L). Many people with diabetes are set a target near this by their doctor, but the target varies from person to person and is decided by your doctor based on your situation.
Does this tool diagnose diabetes?
No. The tool only converts numbers to help you understand them. Diagnosis relies on tests requested and interpreted by a doctor, and is not based on this tool.
What is the difference between average glucose and a fasting reading?
Estimated average glucose summarizes a period of months, while a fasting reading measures a single moment. So they can differ, and each complements the other in following diabetes with your doctor.
