1. What is the eAG Equation?

The eAG (estimated Average Glucose) equation converts HbA1c percentage to average glucose levels in mg/dL. This provides a more intuitive understanding of glucose control for patients and healthcare providers.

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 an estimated average glucose level that corresponds to the HbA1c measurement, helping patients understand their glucose control in more familiar units.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients better understand their diabetes management by relating long-term glucose control to daily glucose measurements they might be more familiar with.

4. Using the Calculator

Tips: Enter HbA1c value as a percentage. The value must be greater than 0. The calculator will provide the corresponding estimated average glucose in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: eAG helps patients relate their HbA1c results to the daily glucose meter readings they're more familiar with, improving understanding of diabetes control.

Q2: How accurate is the eAG conversion?
A: The conversion is based on large clinical studies and provides a good estimate, though individual variations may occur due to differences in glucose fluctuations.

Q3: What is the normal range for eAG?
A: For non-diabetic individuals, eAG is typically below 140 mg/dL. Diabetes management targets vary but often aim for eAG below 154 mg/dL (HbA1c < 7%).

Q4: Can eAG replace daily glucose monitoring?
A: No, eAG is an estimated average and doesn't show glucose variability. Daily monitoring is still essential for making immediate treatment adjustments.

Q5: Are there limitations to this conversion?
A: The conversion may be less accurate in certain conditions like hemoglobin variants, anemia, or renal failure that can affect HbA1c measurements.
