1. What is A1C?

The A1C test measures your average blood glucose levels over the past 2-3 months. It's an important test for diagnosing and monitoring diabetes.

2. How Does the Calculator Work?

The calculator uses the ADA-recommended formula:

Where:

• \( \text{A1C} \) — Glycated hemoglobin percentage

Explanation: This formula provides an estimated average glucose (eAG) that corresponds to your A1C result.

3. Importance of A1C Measurement

Details: A1C reflects long-term glucose control and is used to diagnose prediabetes and diabetes, as well as to monitor treatment effectiveness.

4. Using the Calculator

Tips: Enter your A1C percentage (typically between 4% and 14%). The calculator will estimate your average blood glucose level in mg/dL.

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 treatment plan and stability.

Q3: Does this calculator work for all patients?
A: The relationship between A1C and average glucose may vary in certain conditions like anemia or hemoglobin variants.

Q4: Why convert A1C to average glucose?
A: It helps patients understand their A1C result in terms they're familiar with from daily glucose monitoring.

Q5: Are there limitations to this conversion?
A: The formula provides an estimate; individual variations in glucose fluctuations may affect the actual average.
