1. What is the eAG Calculator?

The eAG (Estimated Average Glucose) calculator converts HbA1c percentage values to average glucose levels in mg/dL, providing a more intuitive understanding of long-term glucose control for diabetes management.

2. How Does the Calculator Work?

The calculator uses the eAG conversion formula:

Where:

• \( HbA1c \) — Glycated hemoglobin percentage
• \( eAG \) — Estimated average glucose in mg/dL

Explanation: This formula provides a linear conversion between HbA1c levels and estimated average glucose levels over the preceding 2-3 months.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients better understand their glucose control in familiar units (mg/dL) and facilitates more effective diabetes management and treatment decisions.

4. Using the Calculator

Tips: Enter the HbA1c percentage value. The calculator will provide the corresponding estimated average glucose level in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between HbA1c and eAG?
A: eAG represents the average glucose level over the previous 2-3 months, which corresponds to the HbA1c percentage measurement.

Q2: What are target eAG levels for diabetes management?
A: Generally, an eAG below 154 mg/dL (HbA1c < 7%) is recommended for most adults with diabetes, though individual targets may vary.

Q3: How accurate is the eAG estimation?
A: The formula provides a good estimation for most individuals, but actual average glucose may vary based on individual glucose patterns and other factors.

Q4: Can eAG be used instead of daily glucose monitoring?
A: No, eAG complements but does not replace daily glucose monitoring, which provides immediate feedback and helps adjust therapy.

Q5: Are there different conversion formulas?
A: Yes, different organizations may use slightly different conversion formulas, but the ADAG study formula (28.7 × HbA1c - 46.7) is widely accepted.
