1. What is A1C?

A1C (glycated hemoglobin) is a blood test that measures your average blood sugar levels over the past 2-3 months. It provides a broader picture of diabetes management than daily glucose readings.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Average Glucose — Your average blood glucose level in mg/dL over a period of time

Explanation: This formula provides an estimated A1C percentage based on your average glucose levels, helping you understand your long-term glucose control.

3. Importance of A1C Measurement

Details: A1C testing is crucial for diabetes management as it reflects average blood sugar levels over time, helping healthcare providers assess treatment effectiveness and adjust medications accordingly.

4. Using the Calculator

Tips: Enter your average glucose level in mg/dL. The value must be greater than 0. For best results, use glucose data from continuous monitoring or frequent testing over several weeks.

5. Frequently Asked Questions (FAQ)

Q1: How often should A1C be tested?
A: Most people with diabetes should have A1C tested every 3-6 months, depending on their treatment plan and stability of glucose levels.

Q2: What are normal A1C values?
A: Below 5.7% is normal, 5.7%-6.4% indicates prediabetes, and 6.5% or higher suggests diabetes. Target levels vary based on individual circumstances.

Q3: How accurate is this calculator?
A: This provides an estimate based on mathematical correlation. For clinical decisions, always rely on laboratory-measured A1C results.

Q4: Can A1C be affected by other factors?
A: Yes, conditions like anemia, hemoglobin variants, kidney disease, and certain medications can affect A1C accuracy.

Q5: What's the difference between A1C and daily glucose readings?
A: Daily readings show immediate glucose levels, while A1C reflects average control over 2-3 months. Both are important for comprehensive diabetes management.
