Estimate Kidney Function with Cockcroft-Gault
Formula
The Cockcroft-Gault equation estimates creatinine clearance (CrCl), a measure of kidney function used for drug dosing adjustments. It uses age, weight, sex, and serum creatinine level.
Normal CrCl is approximately 90-140 mL/min. Values below 60 mL/min suggest significant kidney impairment. Many medications require dose reductions when CrCl drops below certain thresholds.
Common use cases:
- Drug dosing adjustments for kidney function
- Monitoring kidney health over time
- Clinical assessment of renal function
