1. What is the eAG Calculator?

The eAG (Estimated Average Glucose) calculator converts HbA1c values from mmol/mol to mg/dL, providing an estimated average blood glucose level. This helps translate long-term glucose control into more familiar daily glucose measurements.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( HbA1c \) — Glycated hemoglobin in mmol/mol
• \( eAG \) — Estimated Average Glucose in mg/dL

Explanation: This formula provides a mathematical relationship between HbA1c levels and estimated average glucose, allowing for better patient understanding of glucose control.

3. Importance of eAG Calculation

Details: Converting HbA1c to eAG helps patients relate their long-term glucose control to daily blood glucose measurements, improving diabetes management and understanding of treatment goals.

4. Using the Calculator

Tips: Enter HbA1c value in mmol/mol. The value must be a positive number. The calculator will provide the estimated average glucose in mg/dL.

5. Frequently Asked Questions (FAQ)

Q1: Why convert HbA1c to eAG?
A: eAG translates the HbA1c percentage into the same units (mg/dL) as daily glucose monitoring, making it easier for patients to understand their glucose control.

Q2: What is a normal HbA1c range?
A: For non-diabetics, HbA1c is typically below 42 mmol/mol (6.0%). For diabetics, target is usually below 53 mmol/mol (7.0%), but individual targets may vary.

Q3: How often should HbA1c be tested?
A: Most people with diabetes should have HbA1c tested every 3-6 months, depending on their treatment plan and glucose control stability.

Q4: Are there limitations to eAG calculation?
A: eAG provides an average and doesn't show glucose variability. Individual results may vary based on glucose patterns throughout the day.

Q5: Can eAG replace daily glucose monitoring?
A: No, eAG complements but doesn't replace daily glucose monitoring, which shows real-time glucose levels and patterns.
