About
The Cockcroft-Gault equation calculates creatinine clearance to estimate kidney function and guide medication dosing. It considers age, weight, sex, and serum creatinine, incorporating adjustments for body weight when necessary. This widely-used formula helps healthcare providers assess renal function and adjust medication doses accordingly.
Limitations
The equation may be less accurate in elderly patients, those with extreme body weights, or unusual muscle mass. It tends to overestimate GFR in obese patients and underestimate it in elderly or malnourished patients. Results should be interpreted alongside clinical judgment and other kidney function markers.
