what's a glucose test

A glucose test measures the amount of glucose (sugar) in your blood. It is commonly used to diagnose and monitor diabetes and prediabetes. There are several types of glucose tests:

• Fasting Blood Glucose Test: Measures blood sugar after an overnight fast.
• Random Blood Glucose Test: Measures blood sugar at any time, regardless of when you last ate.
• Oral Glucose Tolerance Test (OGTT): Measures blood sugar before and after drinking a sugary drink to see how your body processes glucose.
• A1C Test: Provides an average blood sugar level over the past 2-3 months.

These tests help healthcare providers assess your blood sugar control and determine if you have diabetes or prediabetes.
