The most common tests for measuring blood sugar levels include:
- Fasting Blood Sugar Test: Measures blood glucose after an overnight fast. Normal levels are below 100 mg/dL.
- A1C Test: Provides an average blood sugar level over the past 2-3 months. Results are given as a percentage:
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
- Random Blood Sugar Test: Measures blood sugar at any time, regardless of when you last ate. A level of 200 mg/dL or higher suggests diabetes.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary solution. It’s often used to diagnose gestational diabetes.
These tests help diagnose diabetes, prediabetes, or monitor blood sugar control in people with diabetes.
