Use Cockcroft-Gault CrCl when you need to estimate creatinine clearance with the Cockcroft-Gault equation. Enter Age, Weight, Serum creatinine, and Sex using the definitions and units below so the result can be reproduced.

Age

An integer count or setting from 18 through 120, expressed in years.

Weight

A finite measured or assumed value greater than or equal to 5e-324, expressed in kg.

Serum creatinine

A finite measured or assumed value greater than or equal to 5e-324, expressed in mg/dL.

Sex

A sequence, category, or text value; accepted values are female, male.

The published tool contract uses this rule: Estimate creatinine clearance with the Cockcroft-Gault equation.

Creatinine clearance

The calculated creatinine clearance in mL/min.

The output is an estimate tied to the stated model and coefficients; it is not a direct measurement and should retain that label when reported. It is informational and cannot diagnose a condition, select treatment, or replace professional interpretation of the original measurements. Age must remain between 18 and 120.

Retain the original Age, Weight, Serum creatinine, and Sex values and their units alongside the result. Creatinine-Based Clearance is useful when you instead need to compute renal creatinine clearance as urine volume times urine creatinine divided by plasma creatinine and the collection time in minutes. MDRD eGFR provides another view by helping you estimate glomerular filtration rate with the four variable MDRD equation.

• Creatinine-Based Clearance

  Compute renal creatinine clearance as urine volume times urine creatinine divided by plasma creatinine and the collection time in minutes.

• MDRD eGFR

  Estimate glomerular filtration rate with the four variable MDRD equation.

• BUN Creatinine Ratio

  Compute the blood urea nitrogen to serum creatinine ratio.
