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.
