Glomerular filtration rate stages kidney disease and guides treatment intensity. GFR <15 indicates near end-stage renal disease.
चरण-दर-चरण मार्गदर्शिका
- 1Calculate GFR from serum creatinine using MDRD or CKD-EPI formula
- 2Stage 1: GFR ≥90, Stage 2: 60-89, Stage 3a: 45-59, Stage 3b: 30-44, Stage 4: 15-29, Stage 5: <15
- 3Each stage guides specific interventions

Moderate kidney disease
सामान्य गलतियां जिनसे बचना है
- ✕Using MDRD in patients not meeting formula criteria
- ✕Not adjusting for race or body composition
अक्सर पूछे जाने वाले प्रश्न
Why stage kidney disease?
Each stage has different risk of progression, complications, and treatment urgency.
Why do GFR estimates differ?
Different formulas (MDRD, CKD-EPI) account for different populations. CKD-EPI more accurate.
