1. What is A1C Blood Test?

The A1C test measures your average blood sugar levels over the past 2-3 months. It's a crucial test for diabetes diagnosis and management, showing how well blood sugar is controlled over time.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( eAG \) — Estimated Average Glucose (mg/dL)
• 46.7 and 28.7 — Conversion factors

Explanation: This formula converts average glucose levels (eAG) to the A1C percentage that would be measured in a blood test.

3. Importance of A1C Measurement

Details: A1C is important because it provides a bigger picture of blood sugar control than daily glucose tests. It's used to diagnose prediabetes and diabetes, and to monitor treatment effectiveness.

4. Using the Calculator

Tips: Enter your average glucose level (eAG) in mg/dL. The value must be greater than 0. The calculator will estimate what your A1C test result would likely be.

5. Frequently Asked Questions (FAQ)

Q1: What is a normal A1C level?
A: Below 5.7% is normal, 5.7% to 6.4% indicates prediabetes, and 6.5% or higher on two tests indicates diabetes.

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

Q3: Can A1C be inaccurate?
A: Yes, conditions like anemia or recent blood loss can affect results. Always consult your doctor about test results.

Q4: What's the difference between A1C and daily glucose tests?
A: Daily tests show your blood sugar at one moment, while A1C shows your average over months.

Q5: Can I use this instead of lab testing?
A: No, this is only an estimation. Always rely on actual lab tests for diagnosis and treatment decisions.
