A glucose lab test measures the amount of glucose (sugar) in your blood. It is commonly used to diagnose and monitor diabetes or 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 solution to assess how your body processes glucose.
- Hemoglobin A1C Test: Provides an average blood sugar level over the past 2-3 months.
These tests help healthcare providers evaluate your blood sugar control and determine if you have diabetes or are at risk for developing it.
