Creatinine Clearance (Cockcroft-Gault)
Estimate creatinine clearance for drug dosing and renal function assessment.
- Formula
- CrCl = [(140 - Age) x Weight] / [72 x SCr], x 0.85 if female.
- Clinical context
- Used for drug dosing adjustment, especially renally cleared medications.
- Limitations
- Overestimates CrCl in rapidly changing renal function and is limited at extremes of age or weight.
