如何计算G F R Staging
learn.whatIsHeading
Glomerular filtration rate stages kidney disease and guides treatment intensity. GFR <15 indicates near end-stage renal disease.
分步指南
- 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
例题解析
输入
Age 65, female, African American, Cr 1.4, race factor applied
结果
GFR ≈ 45 (Stage 3b)
Moderate kidney disease
常见错误注意事项
- ✕Using MDRD in patients not meeting formula criteria
- ✕Not adjusting for race or body composition
常见问题
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.
