does a normal blood test show diabetes

A normal blood test typically does not include specific tests for diabetes. However, certain blood tests can indicate diabetes or prediabetes. Here are the key tests used to diagnose diabetes:

• Fasting Plasma Glucose (FPG) Test: Measures blood sugar after an overnight fast. A result of 126 mg/dL or higher indicates diabetes.
• A1C Test: Measures average blood sugar levels over the past 2-3 months. An A1C level of 6.5% or higher indicates diabetes.
• Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a glucose-rich drink. A result of 200 mg/dL or higher after 2 hours indicates diabetes.

If you suspect you have diabetes, ask your healthcare provider for these specific tests.
