A1C Formula:
From: | To: |
The A1C test measures your average blood sugar level over the past 2-3 months. It's an important tool for diabetes management and diagnosis.
The calculator uses the ADAG formula:
Where:
Explanation: This formula converts average glucose levels to the A1C percentage that doctors use to monitor diabetes control.
Details: A1C 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.
Tips: Enter your average glucose level in mg/dL based on meter readings or continuous glucose monitoring data.
Q1: What's 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: Every 3 months if changing treatment or not meeting goals, every 6 months if stable and meeting targets.
Q3: Can A1C be inaccurate?
A: Yes, conditions like anemia or recent blood loss can affect results. Discuss with your doctor if concerned.
Q4: What's the difference between A1C and eAG?
A: A1C shows long-term control (%), while eAG translates this to average glucose levels (mg/dL).
Q5: Should I use this instead of lab tests?
A: No, this is for estimation only. Always follow up with lab tests as recommended by your healthcare provider.
