Creatinine Clearance (Cockcroft-Gault Equation) Calculator

The Creatinine Clearance Calculator is a simple yet powerful tool designed to help healthcare professionals and patients calculate their Creatinine Clearance (CrCl) using the Cockcroft-Gault equation. This tool is particularly useful in assessing kidney function and determining the appropriate dosage of medications that are excreted through the kidneys.

With the option to toggle between different units of measurement (e.g., kg ↔ lb, µmol/L ↔ mg/dL, cm ↔ inches), this calculator ensures flexibility and ease of use for users worldwide.

✅ Key Features of the Tool

• Accurate CrCl Calculation using the Cockcroft-Gault equation
• Unit Conversion: Easily switch between metric and imperial units (e.g., kg to lb, cm to inches)
• Dynamic Color Bar Indicator: Displays whether the CrCl result is in the low, normal, or high range
• Responsive Design: Works perfectly on both desktop and mobile devices
• User-Friendly Interface: Clean and intuitive design with easy-to-use input fields and interactive conversion arrows

🎯 How the Calculator Works

The calculator takes the following inputs:

1. Age (in years)
2. Weight (toggle between kg and lb)
3. Serum Creatinine Level (toggle between µmol/L and mg/dL)
4. Height (optional, toggle between cm and inches)

Based on the provided values, it calculates the Creatinine Clearance (CrCl) using the formula:

CrCl (mL/min) = [(140 - Age) × Weight] / (Serum Creatinine × 0.813)

For females, the result is multiplied by 0.85 to adjust for gender differences in muscle mass.

🚦 Understanding the Results

After the calculation, the tool provides a color-coded bar to indicate the CrCl result:

• 🔴 Low (CrCl < 60 mL/min) – May indicate impaired kidney function
• 🟢 Normal (CrCl 60-120 mL/min) – Indicates normal kidney function
• 🔵 High (CrCl > 120 mL/min) – May be normal or indicate higher muscle mass or other factors

The result also includes the BMI if the height is provided, helping users assess their overall health.

💡 When to Use the Calculator

This tool is ideal for:

• Healthcare professionals to adjust medication dosages based on kidney function
• Patients to monitor their kidney health
• Pharmacists to calculate the appropriate drug clearance rates
