HbA1c to Estimated Average Glucose
The HbA1c test is not measured in the usual unit measurements like regular blood sugar tests (mg/dl and mmol/l). Instead, it is usually reported as a percentage of total hemoglobin. Therefore you will see your HbA1c results like this 6.5% as opposed to 6.5 mg/dl or 117 mmol/l. Use the facility below to determine your average blood sugar level based on your Hba1c result.

OBJECTIVE—The A1C assay, expressed as the percent of hemoglobin that is glycated, measures chronic glycemia and is widely used to judge the adequacy of diabetes treatment and adjust therapy. Day-to-day management is guided by self-monitoring of capillary glucose concentrations (milligrams per deciliter or millimoles per liter). We sought to define the mathematical relationship between A1C and average glucose (AG) levels and determine whether A1C could be expressed and reported as AG in the same units as used in self-monitoring.
