1. What is the eAG Formula?

The eAG (Estimated Average Glucose) formula converts A1C percentage to an average glucose value in mg/dL. This helps translate A1C results into more familiar glucose measurement units that patients use daily.

2. How Does the Calculator Work?

The calculator uses the eAG formula:

Where:

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

Explanation: This linear equation provides an estimated average glucose level that corresponds to the A1C measurement over the previous 2-3 months.

3. Importance of eAG Calculation

Details: Converting A1C to eAG helps patients better understand their diabetes control by relating it to their daily glucose monitoring numbers, improving diabetes management and treatment adherence.

4. Using the Calculator

Tips: Enter A1C value as a percentage (e.g., 6.5). The calculator will provide the corresponding estimated average glucose in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between A1C and average glucose?
A: A1C represents the average blood glucose level over the past 2-3 months. The eAG formula converts this percentage to mg/dL units.

Q2: What A1C range is considered normal?
A: For non-diabetics, A1C is typically below 5.7%. 5.7%-6.4% indicates prediabetes, and 6.5% or higher suggests diabetes.

Q3: How accurate is the eAG conversion?
A: The formula provides a good estimate, but individual variations exist due to factors like red blood cell lifespan and glucose fluctuations.

Q4: Can eAG replace daily glucose monitoring?
A: No, eAG provides an average but doesn't show glucose variability or hypoglycemic episodes that daily monitoring captures.

Q5: Are there different conversion formulas?
A: Yes, some organizations use slightly different coefficients, but 28.7 and 46.7 are widely accepted values from the ADAG study.
