1. What is the eAG Equation?

The eAG (Estimated Average Glucose) equation converts A1C percentage to average blood sugar levels. This provides a more intuitive understanding of glucose control for diabetes management.

2. How Does the Calculator Work?

The calculator uses the eAG equation:

Where:

• \( A1C \) — Glycated hemoglobin percentage
• \( eAG \) — Estimated Average Glucose in mg/dL

Explanation: This linear equation provides an estimated average blood glucose level that corresponds to a given A1C value.

3. Importance of eAG Calculation

Details: Converting A1C to eAG helps patients better understand their glucose control in familiar units (mg/dL) and facilitates more effective diabetes management discussions between patients and healthcare providers.

4. Using the Calculator

Tips: Enter A1C value as a percentage (e.g., 6.5 for 6.5%). The value must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between A1C and average blood sugar?
A: A1C represents average blood glucose levels over the past 2-3 months. The eAG equation converts this percentage to an estimated average glucose value in mg/dL.

Q2: How accurate is the eAG conversion?
A: The eAG equation provides a good estimate for most people, but individual variations in red blood cell lifespan and other factors can affect the accuracy.

Q3: What A1C range is considered normal?
A: For non-diabetic individuals, A1C is typically below 5.7%. Values between 5.7-6.4% indicate prediabetes, and 6.5% or higher suggests diabetes.

Q4: Should eAG replace regular blood glucose monitoring?
A: No, eAG provides an average but doesn't show glucose variability. Regular self-monitoring is still important for daily diabetes management.

Q5: Are there different conversion formulas?
A: Yes, some organizations use slightly different formulas, but the ADAG study formula (28.7 × A1C - 46.7) is widely accepted and used.
