A glucose test in blood measures the amount of glucose (sugar) in your bloodstream. 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.
- Hemoglobin A1C Test: Provides an average blood sugar level over the past 2-3 months.
These tests help healthcare providers assess how well your body manages glucose and determine if you have diabetes or are at risk for developing it.
