1. What is the eAG Equation?

The eAG (estimated Average Glucose) equation converts HbA1c percentage to an average glucose value in mg/dL. This helps patients and healthcare providers better understand what HbA1c results mean in terms of daily glucose levels.

2. How Does the Calculator Work?

The calculator uses the eAG equation:

Where:

• \( HbA1c \) — Glycated hemoglobin percentage
• 28.7 and 46.7 — Conversion coefficients

Explanation: The equation provides an estimated average glucose level that corresponds to the HbA1c measurement over the previous 2-3 months.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients better understand their diabetes control in terms of daily glucose measurements they are familiar with, improving diabetes management and treatment adherence.

4. Using the Calculator

Tips: Enter HbA1c value as a percentage (e.g., 6.5). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: eAG provides glucose values in familiar units (mg/dL) that patients use with their glucose meters, making HbA1c results more understandable.

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 is the normal range for eAG?
A: For non-diabetic individuals, eAG is typically below 140 mg/dL, corresponding to an HbA1c below 6.5%.

Q4: Can eAG replace daily glucose monitoring?
A: No, eAG provides an average but doesn't show glucose variability. Daily monitoring is still essential for diabetes management.

Q5: Are there limitations to this conversion?
A: The conversion may be less accurate in individuals with certain medical conditions that affect red blood cell turnover or hemoglobin variants.
