Calculadora de Depuración de Creatinina
Calcula la depuración de creatinina con la fórmula de Cockcroft-Gault para función renal.
Creatinine Clearance
100.0 mL/min
Creatinine Clearance vs Age
Fórmula
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
Ejemplo Resuelto
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)
Preguntas Frecuentes
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.
