The Cockcroft-Gault formula estimates creatinine clearance (CrCl) to assess renal function using age, weight, sex, and serum creatinine — crucial for adjusting drug dosages in patients with impaired kidney function.

The Cockcroft-Gault Creatinine Clearance (CrCl) Calculator is a widely used tool to estimate a patient’s kidney function. It uses a formula incorporating a patient’s age, weight, sex, and serum creatinine level to calculate an estimated creatinine clearance in mL/min. This estimate is crucial for healthcare professionals, particularly for adjusting drug dosages in patients with impaired kidney function, ensuring medication safety and efficacy. While newer equations exist, Cockcroft-Gault remains commonly referenced due to its historical use in drug development studies.
Our calculators apply published formulas as precisely as we can. Even so, no formula captures every detail of a real patient. Use the result as one input to your own assessment, not the final word.
