does glucose test show diabetes

A glucose test can help indicate diabetes, but it is not the only test used for diagnosis. Here are the common 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 on two separate tests 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 suggests diabetes.
• Hemoglobin A1C Test: Reflects average blood sugar levels over the past 2-3 months. An A1C level of 6.5% or higher indicates diabetes.

While a glucose test (like FPG or OGTT) can show elevated blood sugar levels, the A1C test is often used alongside these tests for a more comprehensive diagnosis. Always consult a healthcare provider for accurate diagnosis and management.
