Creatinine Clearance Calculator

Calculate creatinine clearance using Cockcroft-Gault equation

About this calculator

The Creatinine Clearance Calculator uses the Cockcroft-Gault equation to estimate kidney function by measuring how efficiently your kidneys filter creatinine from your blood. This calculation is essential for healthcare providers to assess renal function, adjust medication dosages, and monitor kidney health over time. The tool provides a quick, reliable estimate of glomerular filtration rate, helping detect early kidney disease and guide treatment decisions for patients with various medical conditions.

How to use

Enter your age, weight, and serum creatinine level into the calculator fields. Select your gender from the dropdown menu, as the equation uses different calculations for males and females. Click calculate to get your creatinine clearance result in mL/min, which indicates your kidney's filtering capacity.

Frequently asked questions

What is a normal creatinine clearance range?

Normal creatinine clearance ranges from 90-120 mL/min for healthy adults. Values below 60 mL/min may indicate kidney dysfunction requiring medical evaluation.

How accurate is the Cockcroft-Gault equation?

The Cockcroft-Gault equation provides good estimates for most adults but may be less accurate in elderly, obese, or very thin patients.

When should I check my creatinine clearance?

Regular monitoring is recommended for patients with diabetes, hypertension, kidney disease, or those taking medications that affect kidney function.
