Frequently Asked Questions

Trova risposte rapide

What is hemoglobin A1c?

Hemoglobin A1c (HbA1c) is a form of hemoglobin that is chemically linked to glucose. It reflects average blood glucose levels over the past 2-3 months and is used to diagnose and monitor diabetes.

How accurate is this calculator?

This calculator uses the American Diabetes Association (ADA) formula: A1c = (46.7 + average glucose in mg/dL) / 28.7. While it provides a good estimate, laboratory testing is required for precise clinical diagnosis.

What glucose units does the calculator support?

The calculator supports both mg/dL (milligrams per deciliter) and mmol/L (millimoles per liter) units. You can switch between them using the unit selector.

Can I calculate glucose from A1c?

Yes, the calculator works both ways. You can calculate estimated A1c from glucose values, or calculate estimated average glucose from an A1c percentage.
