Yes, a blood test can detect diabetes. The most common blood tests used to diagnose diabetes include:
- A1C Test: Measures your average blood sugar levels over the past 2-3 months. An A1C level of 6.5% or higher indicates diabetes.
- Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast. A level of 126 mg/dL or higher suggests diabetes.
- Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary drink. A level of 200 mg/dL or higher after 2 hours indicates diabetes.
These tests help healthcare providers diagnose diabetes and monitor its management.
