Community AnswerAnswered by Dr. Emily Smith 🩺Answered: 1/12/2025The A1C test is a simple blood test that measures your average blood sugar levels over the past 2-3 months. Here’s how it works: Where to Get Tested: The A1C test is typically done in a doctor’s office or a lab. Preparation: No fasting is required before the test, but your doctor may recommend other tests (like cholesterol) that might require fasting. Procedure: A healthcare professional will draw a small blood sample from your finger or arm. Results: The results are given as a percentage. Normal levels are below 5.7%, prediabetes is 5.7% to 6.4%, and diabetes is 6.5% or above. For more detailed information, you can visit the CDC's A1C Test page.
