Glomerular filtration rate stages kidney disease and guides treatment intensity. GFR <15 indicates near end-stage renal disease.
Hướng dẫn từng bước
- 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

Age 65, female, African American, Cr 1.4, race factor applied
Kết quả
GFR ≈ 45 (Stage 3b)
Moderate kidney disease
Lỗi thường gặp cần tránh
- ✕Using MDRD in patients not meeting formula criteria
- ✕Not adjusting for race or body composition
Câu hỏi thường gặp
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.
