Glucose in a blood test refers to the measurement of the amount of sugar (glucose) present in your bloodstream. This test is commonly used to diagnose and monitor diabetes and prediabetes. Here’s what you need to know:

• Purpose: The test helps determine if your blood sugar levels are within a normal range or if you have diabetes or prediabetes.
• Types of 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.

If your results are outside the normal range, it may indicate diabetes or prediabetes. Consult your healthcare provider for further evaluation and management.
