Estimated glomerular filtration rate (eGFR)
Bladder and kidney healtheGFR (estimated Glomerular Filtration Rate): Calculated using the CKD-EPI formula based on creatinine level, age, sex, and ethnic background.
It estimates how much blood your kidneys filter per minute, with normal values typically above 90 ml/min/1.73m². Values below 60 ml/min/1.73m² indicate moderate kidney impairment, while values below 30 ml/min/1.73m² signifies severe impairment.

Why this matters
eGFR reveals potential kidney health issues before serious symptoms appear. Normal values are typically above 90 ml/min/1.73m². Values below 60 ml/min/1.73m² indicate moderate kidney impairment, while values below 30 ml/min/1.73m² signifies severe impairment. Early warning signs may include fatigue, swelling, or changes in urination.
Monitoring eGFR helps track kidney function over time, supporting lifestyle measures such as blood pressure control, hydration, and avoiding kidney-damaging medications.
