what is glucose in a blood test

Glucose in a blood test refers to the measurement of the amount of sugar (glucose) present in your bloodstream. Glucose is a primary source of energy for your body's cells and is derived from the foods you eat. The test is commonly used to:

• Diagnose Diabetes: High glucose levels may indicate diabetes or prediabetes.
• Monitor Diabetes Management: For individuals with diabetes, it helps track how well blood sugar levels are controlled.
• Assess Overall Health: Abnormal glucose levels can also indicate other health issues.

There are different types of blood glucose tests, including:

• 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.
• A1C Test: Provides an average blood glucose level over the past 2-3 months.

Normal fasting blood glucose levels are typically between 70-99 mg/dL. Levels above this range may indicate prediabetes or diabetes.
