Organ Function
eGFR
Estimated glomerular filtration rate — measures how well your kidneys filter waste from the blood.
Optimal Range
> 90 mL/min (optimal) · 60-89 (mild decline)
Why It Matters
Kidney function declines with age and is a powerful predictor of cardiovascular events and mortality. Early detection of declining eGFR allows intervention through blood pressure management, hydration, and medication adjustment.
