24 Hours Creatinine Clearance Calculator



Welcome to the 24 Hours Creatinine Clearance Calculator, a powerful tool designed to estimate the renal function by calculating the creatinine clearance rate over a 24-hour period. This article will guide you through the usage of the calculator, explain the underlying formula, provide an example for better understanding, address frequently asked questions, and conclude with the importance of monitoring creatinine clearance.

How to Use

Using the 24 Hours Creatinine Clearance Calculator is straightforward. Simply input the required values into the designated fields, press the “Calculate” button, and receive the estimated creatinine clearance rate. This tool is particularly useful for healthcare professionals, researchers, and anyone interested in assessing kidney function.


The creatinine clearance rate is calculated using the Cockcroft-Gault equation, a widely accepted formula for estimating renal function. The formula is as follows:


  • Age is the age of the individual in years.
  • Weight is the weight of the individual in kilograms.
  • Serum creatinine is the serum creatinine concentration in mg/dL.
  • Constant is 1.23 for men and 1.04 for women.
  • k is 0.85 for females.


Let’s consider a 40-year-old male with a weight of 70 kg and a serum creatinine level of 1.2 mg/dL.

In this example, the estimated creatinine clearance rate is 92.5 mL/min.


Q: Why is creatinine clearance important?

Creatinine clearance is a crucial indicator of kidney function, helping assess how efficiently the kidneys are filtering waste from the blood. Monitoring creatinine clearance is essential for diagnosing and managing various renal conditions.

Q: Can this calculator be used for all age groups?

Yes, the calculator is suitable for adults. However, it is not recommended for use in pediatric populations.

Q: Are there any limitations to the Cockcroft-Gault equation?

While widely used, the Cockcroft-Gault equation may have limitations in certain populations, such as those with extremes in muscle mass or abnormal body composition.


The 24 Hours Creatinine Clearance Calculator simplifies the estimation of renal function using the trusted Cockcroft-Gault equation. Regular monitoring of creatinine clearance is crucial for the early detection and management of kidney-related issues. Embrace this tool to make informed decisions regarding kidney health.
