Calculate creatinine clearance and assess kidney function.
Cockcroft–Gault estimate = [(140 − Age) × Weight] ÷ (72 × Serum creatinine), with the applicable sex adjustment.The estimate uses the measurement, age and other fields requested by the selected equation. Laboratory methods, units, timing, medication, medical history and population-specific limitations can materially affect interpretation.
Creatinine Clearance Calculator applies an educational screening or laboratory-related equation to the information entered. Calculate creatinine clearance and assess kidney function. It helps explain a numeric relationship but cannot confirm a diagnosis or individual medical risk.
It is an estimate generated from the values entered on this page and the calculation method shown in the formula and methodology sections.
The calculator validates the entered values, applies the protected formula shown on the page and then rounds only the displayed result where appropriate.
Use current source values, confirm units and time periods, include every requested cost or measurement, and avoid rounding inputs before the final calculation.
Different calculators may use different assumptions, time periods, rounding rules, reference standards or included costs. Compare the inputs and limitations before comparing answers.
No. It is an educational estimate and cannot account for every medical history, medication, measurement issue or individual biological factor.
Recalculate whenever a material input changes, such as a rate, price, balance, measurement, time period, fee, contribution or project dimension.
Use a recent value from a reliable measurement source and verify the unit before calculating. Discuss unexpected or abnormal results with a qualified clinician rather than changing treatment based on the calculator.
