1. What is the A1C Calculator?

The A1C calculator estimates hemoglobin A1C (glycated hemoglobin) from average glucose levels (eAG). This is based on the Diabetes Canada recommended equation and provides an important measure of long-term blood glucose control.

2. How Does the Calculator Work?

The calculator uses the Diabetes Canada equation:

Where:

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

Explanation: The equation converts average glucose levels over the past 2-3 months into an A1C percentage, which reflects the percentage of hemoglobin that has glucose attached to it.

3. Importance of A1C Measurement

Details: A1C is a crucial marker for diabetes management, providing a 2-3 month average of blood glucose levels. It's used for both diagnosis and monitoring of diabetes.

4. Using the Calculator

Tips: Enter your average glucose level in mg/dL. The value should be based on multiple glucose measurements over time for accurate results.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal A1C level?
A: Below 5.7% is normal, 5.7%-6.4% indicates prediabetes, and 6.5% or higher suggests diabetes.

Q2: How often should A1C be tested?
A: For diabetes management, typically every 3-6 months depending on control and treatment plan.

Q3: Can A1C be inaccurate in some cases?
A: Yes, conditions affecting hemoglobin (like anemia) or recent blood loss can affect A1C accuracy.

Q4: What's the difference between A1C and eAG?
A: A1C shows percentage of glycated hemoglobin, while eAG converts this to average glucose in mg/dL.

Q5: Why use the Diabetes Canada equation specifically?
A: Diabetes Canada provides this equation as their standard for converting between A1C and eAG values.
