About
Creatinine clearance (CrCl) estimates kidney function and is commonly used for drug dosing adjustments. The Cockcroft-Gault equation estimates CrCl from serum creatinine, age, weight, and sex. Unlike eGFR, this value is not normalized to body surface area, making it particularly useful for drug dosing in clinical practice.
Formula
CrCl = [(140 − Age) × Weight (kg)] / [72 × Serum Creatinine (mg/dL)]
If female: multiply result by 0.85
Interpretation
| CrCl (mL/min) | Kidney Function |
|---|---|
| ≥ 90 | Normal |
| 60 – 89 | Mild decrease |
| 30 – 59 | Moderate decrease |
| 15 – 29 | Severe decrease |
| < 15 | Kidney failure |
