Creatinine clearance estimates kidney filtration from serum creatinine and body size. It is not a diagnosis and may differ from lab-reported eGFR.

Test how a different serum creatinine value changes the Cockcroft-Gault estimate.
Calculate your baseline first
It uses the Cockcroft-Gault equation: ((140 − age) × weight in kg) ÷ (72 × serum creatinine). For female sex, the result is multiplied by 0.85.
No. Creatinine clearance from Cockcroft-Gault is commonly used for medication dosing estimates, while eGFR is often reported by laboratories for kidney function staging. They can produce different numbers.
No. This tool provides an estimate only. Kidney assessment depends on clinical history, repeat labs, urine testing, medications, hydration status and clinician interpretation.
