Glucose
- Sample Type
- Standard
- Fasting
- No
- Unit
- mg/dL
Glucose is the primary energy source for the body's cells and is the key marker for carbohydrate metabolism. In a clinical panel, it is used to diagnose and monitor Diabetes Mellitus (Type 1, Type 2, and Gestational) and to evaluate metabolic disorders. Precise regulation is maintained by insulin and glucagon; chronic elevation (hyperglycemia) leads to systemic microvascular and macrovascular damage, while acute drops (hypoglycemia) can cause immediate neurological impairment.

Why Context Matters
Fasting status is the most common confounder. Additionally, acute stress, recent surgery, corticosteroid use, and severe infection can transiently elevate glucose levels (stress hyperglycemia) without indicating chronic diabetes. Conversely, heavy alcohol consumption or intense exercise can cause unexpected drops.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
