Translating A1C to Daily Blood Sugar
While A1C is reported as a percentage, daily blood sugar is measured in mg/dL or mmol/L. The Estimated Average Glucose (eAG) metric helps patients bridge this gap, showing what their overall average blood sugar looks like on a day-to-day basis.
The ADAG Mathematical Relationship
The mathematical link between A1C and average blood sugar was established by the A1C-Derived Average Glucose (ADAG) study, which collected thousands of glucose readings from patients worldwide to map HbA1c to mean glucose levels.
Why Daily Readings Fluctuate Around the Average
An average glucose level of 126 mg/dL (A1C of 6.0%) doesn't mean your blood sugar is always 126. It will naturally rise after meals and fall during sleep. eAG represents the middle of all these fluctuations.
When to Seek Urgent Medical Attention
- Glycemic swings accompanied by severe shakiness, confusion, or cold sweats.
- High blood sugar with persistent vomiting, deep breathing, or confusion.
- Unexplained vision changes, tingling in feet, or rapid weight loss.
Frequently Asked Questions
Estimated Average Glucose (eAG) is a translation of your A1C percentage into the same units (mg/dL or mmol/L) used in daily home finger-stick glucose meters.
The formula is: eAG (mg/dL) = (28.7 * A1C) - 46.7. This standard translation is recommended by the American Diabetes Association (ADA).
