| Item | Formula / Note | Source / Standard |
|---|---|---|
| Equation choice | adults use creatinine based equations while children need the Schwartz equation | CKD-EPI 2009 creatinine equation (optional race coefficient) |
| Albumin staging | staging uses both filtration rate and albuminuria dimensions | KDIGO 2012, CKD evaluation |
| Dose adjustment | renally cleared drugs need dose adjustment as filtration falls | WHO Model Formulary |
