does diabetes show up in blood test

Yes, diabetes can be diagnosed through blood tests. 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 Blood Sugar 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 liquid. A level of 200 mg/dL or higher after 2 hours indicates diabetes.

These tests help healthcare providers determine if you have diabetes or prediabetes.
