The primary blood test used to diagnose and monitor diabetes is the A1C test, also known as the hemoglobin A1C or HbA1c test. This test measures your average blood sugar levels over the past 2 to 3 months. It is a simple blood test that does not require fasting.
Key Points:
- A1C Test: Measures the percentage of your red blood cells that have sugar-coated hemoglobin.
- Normal Range: Below 5.7%
- Prediabetes Range: 5.7% to 6.4%
- Diabetes Range: 6.5% or above
Other tests that may be used include:
- Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary liquid.
- Random Blood Sugar Test: Measures blood sugar at any time, regardless of when you last ate.
