Metabolic
Fasting Glucose
Blood sugar level measured after an overnight fast — a basic but important metabolic marker.
Optimal Range
72-85 mg/dL (optimal) · < 100 mg/dL (normal)
Why It Matters
Fasting glucose reveals baseline blood sugar regulation. Levels above 85 mg/dL, while clinically 'normal,' are associated with increased long-term metabolic and cardiovascular risk.
