learn.whatIsHeading
Glomerular filtration rate stages kidney disease and guides treatment intensity. GFR <15 indicates near end-stage renal disease.
Panduan Langkah demi Langkah
- 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

Why do GFR estimates differ?
Different formulas (MDRD, CKD-EPI) account for different populations. CKD-EPI more accurate.
