1. What is eAG (Estimated Average Glucose)?

Estimated Average Glucose (eAG) converts HbA1c percentage to the same units (mg/dL) as daily glucose meter readings, helping patients understand their average blood glucose levels over the past 2-3 months in more familiar terms.

2. How Does the Calculator Work?

The calculator uses the eAG conversion formula:

Where:

• \( HbA1c \) — Glycated hemoglobin percentage
• 28.7 — Conversion coefficient
• 46.7 — Adjustment factor

Explanation: This linear equation provides an estimated average glucose level that corresponds to the HbA1c measurement, allowing for better patient understanding and diabetes management.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients relate their long-term glucose control to their daily glucose meter readings, improving diabetes education and self-management motivation.

4. Using the Calculator

Tips: Enter HbA1c value as a percentage (e.g., 6.5 for 6.5%). The calculator will provide the estimated average glucose in mg/dL, which corresponds to typical glucose meter readings.

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: eAG helps patients understand their average blood glucose levels in the same units as their daily glucose meter readings, making the HbA1c result more meaningful.

Q2: How accurate is the eAG conversion?
A: The conversion is based on large clinical studies and provides a reliable estimate of average glucose levels over the previous 2-3 months.

Q3: What are target eAG levels?
A: For most adults with diabetes, target eAG is typically below 154 mg/dL, which corresponds to an HbA1c below 7%.

Q4: Does eAG replace daily glucose monitoring?
A: No, eAG complements daily monitoring by providing a long-term average, while daily readings help with immediate treatment adjustments.

Q5: Are there limitations to eAG calculation?
A: The conversion assumes a consistent relationship between average glucose and HbA1c, which may vary slightly between individuals.
