A glucose blood test is used to measure the amount of glucose (sugar) in your blood. It is primarily used to:

• Diagnose Diabetes: Helps determine if you have diabetes or prediabetes.
• Monitor Diabetes: Tracks how well your diabetes is being managed over time.
• Check for Hypoglycemia or Hyperglycemia: Identifies if your blood sugar levels are too low or too high.

There are different types of glucose blood tests, including:

• Fasting Blood Sugar Test: Measures blood sugar after an overnight fast.
• Random Blood Sugar 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.
• A1C Test: Provides an average blood sugar level over the past 2-3 months.

These tests are crucial for managing and preventing complications related to diabetes.
