Creatinine Clearance (Cockcroft–Gault) Calculator estimates kidney function by calculating creatinine clearance in mL/min. It uses serum creatinine, age, weight, and gender to provide an estimate of renal function, which is useful in assessing dosing for many medications. The formula is: CrCl = [(140 – age) × weight (kg) × 0.85 if female] / (72 × serum creatinine). Although widely used for decades, this formula has limitations such as overestimating kidney function and not being adjusted for standardized creatinine assays or body surface area. It should be used with caution and not as the sole guide for clinical decisions.
