Several blood tests are commonly used to diagnose and monitor diabetes:
-
A1C Test: Measures your average blood sugar levels over the past 2-3 months. It is used to diagnose prediabetes and diabetes and to monitor how well your diabetes is being managed.
- Normal: Below 5.7%
- Prediabetes: 5.7% to 6.4%
- Diabetes: 6.5% or above
-
Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast.
- Normal: Less than 100 mg/dL
- Prediabetes: 100 to 125 mg/dL
- Diabetes: 126 mg/dL or higher
-
Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary drink. It is often used to diagnose gestational diabetes.
- Normal: Less than 140 mg/dL
- Prediabetes: 140 to 199 mg/dL
- Diabetes: 200 mg/dL or higher
-
Random Blood Sugar Test: Measures blood sugar at any time of the day, regardless of when you last ate.
- Diabetes: 200 mg/dL or higher (with symptoms of diabetes)
These tests help healthcare providers determine if you have diabetes or prediabetes and how well your treatment plan is working.
