Estimez la fonction rénale avec l'équation de Cockcroft-Gault.
Creatinine Clearance
100.0 mL/min
Creatinine Clearance vs Age
Formule
Cockcroft-Gault Equation
CrCl = [(140 - Age) x Weight(kg)] / [72 x Serum Creatinine] x (0.85 if female)
This equation estimates creatinine clearance as a proxy for glomerular filtration rate (GFR).
Kidney Function Stages
Exemple Résolu
A 50-year-old male, 80 kg, serum creatinine 1.0 mg/dL.
- 01CrCl = (140 - 50) x 80 / (72 x 1.0)
- 02= 90 x 80 / 72
- 03= 7200 / 72 = 100 mL/min (Normal)
Questions Fréquentes
What is creatinine clearance?
Creatinine clearance measures how well the kidneys filter creatinine from the blood. It serves as an estimate of the glomerular filtration rate (GFR).
Why is this equation important?
The Cockcroft-Gault equation is widely used for adjusting drug dosages in patients with reduced kidney function. Many drug labels reference this equation.
What is a normal creatinine level?
Normal serum creatinine is typically 0.7-1.3 mg/dL for men and 0.6-1.1 mg/dL for women. Higher values may indicate reduced kidney function.
