A blood glucose test measures the amount of glucose (sugar) in your blood. Glucose is a primary source of energy for your body's cells, and its levels are tightly regulated by insulin, a hormone produced by the pancreas.
Types of Blood 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 consuming a sugary drink to assess how your body processes glucose.
- Hemoglobin A1C Test: Provides an average blood glucose level over the past 2-3 months.
Why It's Important:
- Diagnosis: Helps diagnose prediabetes, diabetes, or gestational diabetes.
- Monitoring: Tracks how well diabetes is being managed.
- Prevention: Identifies risk factors for developing diabetes.
