1. What is the A1C to Glucose Conversion?

The estimated Average Glucose (eAG) calculation converts hemoglobin A1C values to an average blood glucose level. This helps patients and clinicians understand A1C results in the same units as daily glucose measurements (mg/dL).

2. How Does the Calculator Work?

The calculator uses the ADAG (A1C-Derived Average Glucose) study formula:

Where:

• \( eAG \) — Estimated average glucose (mg/dL)
• \( A1C \) — Hemoglobin A1C percentage

Explanation: The formula was derived from a large international study that correlated A1C values with continuous glucose monitoring data.

3. Importance of eAG Calculation

Details: eAG helps translate A1C results into more familiar glucose measurement units, making it easier for patients to understand their diabetes control and relate it to their daily glucose monitoring.

4. Using the Calculator

Tips: Enter A1C value as a percentage (typically between 4-15%). The calculator will provide the corresponding average glucose level in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: Why convert A1C to eAG?
A: Many patients are more familiar with daily glucose readings in mg/dL than with A1C percentages. eAG helps bridge this understanding gap.

Q2: How accurate is the eAG calculation?
A: The formula is based on extensive research but represents an average. Individual variations in glucose patterns can affect the relationship between A1C and average glucose.

Q3: Does eAG replace A1C testing?
A: No, eAG is derived from A1C and doesn't replace it. A1C remains the gold standard for assessing long-term glucose control.

Q4: What's the difference between eAG and daily glucose readings?
A: eAG represents an average over 2-3 months, while daily readings show moment-to-moment variations. Both are important for diabetes management.

Q5: Are there limitations to this conversion?
A: The relationship may be less accurate in conditions that affect red blood cell turnover (like anemia) or in certain ethnic populations.
