what is glu in blood test

In a blood test, GLU stands for glucose, which is a type of sugar that serves as the primary source of energy for your body's cells. Glucose levels in the blood are a key indicator of how well your body is managing blood sugar, and they are commonly measured to diagnose or monitor conditions like diabetes and prediabetes.

Normal Blood Glucose Levels:

• Fasting Blood Sugar (FBS): 70–99 mg/dL (milligrams per deciliter)
• Postprandial (after meals): Less than 140 mg/dL
• A1C Test: Below 5.7% (indicates average blood sugar over the past 2–3 months)

Why is it important?

• High Glucose Levels: May indicate diabetes or prediabetes.
• Low Glucose Levels: Could suggest hypoglycemia, which can cause symptoms like dizziness, confusion, or fainting.

If your glucose levels are outside the normal range, consult your healthcare provider for further evaluation and management.
