1. What is the eAG Equation?

The eAG (estimated Average Glucose) equation converts HbA1c percentage to an estimated average glucose level in mg/dL. This provides a more intuitive understanding of average blood glucose levels over the previous 2-3 months.

2. How Does the Calculator Work?

The calculator uses the eAG equation:

Where:

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

Explanation: The equation provides a linear conversion from HbA1c percentage to estimated average glucose levels in mg/dL.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients better understand their average glucose levels and facilitates more effective diabetes management and treatment adjustments.

4. Using the Calculator

Tips: Enter HbA1c value as a percentage. The value must be valid (HbA1c > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: eAG provides a more intuitive measure that corresponds to daily glucose meter readings, helping patients better understand their diabetes control.

Q2: What is the relationship between HbA1c and average glucose?
A: HbA1c represents the average blood glucose level over the past 2-3 months. The conversion formula provides an estimated average glucose value.

Q3: How accurate is the eAG conversion?
A: The conversion is based on large clinical studies and provides a reliable estimate, though individual variations may occur.

Q4: What are target eAG levels?
A: Target eAG levels typically correspond to HbA1c targets. For example, an HbA1c of 7% corresponds to an eAG of approximately 154 mg/dL.

Q5: Can this calculator be used for diabetes diagnosis?
A: No, this calculator is for educational purposes only. Diabetes diagnosis should be made by healthcare professionals using appropriate diagnostic criteria.
