Kuinka laskea G F R Staging
Mikä on G F R Staging?
Glomerular filtration rate stages kidney disease and guides treatment intensity. GFR <15 indicates near end-stage renal disease.
Vaiheittainen opas
- 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

Usein kysytyt kysymykset
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.
