Creatinine Clearance Calculator

This Creatinine Clearance Calculator helps users estimate their creatinine clearance using the Cockcroft-Gault formula, adjust it for body surface area, and categorize their renal function based on input parameters such as gender, age, weight, and serum creatinine levels.

How to Use the Creatinine Clearance Calculator

This guide will walk you through the steps to use the Creatinine Clearance Calculator effectively. Please follow each step carefully and make sure you have all the necessary information available.

Step 1: Gather Required Information

To use the calculator, you need the following information:

  • Gender: Male or Female
  • Age: in years (between 18 and 120).
  • Weight: in kilograms (between 20 and 300).
  • Serum Creatinine: in mg/dL (between 0.1 and 20), ensuring the measurement is recent and accurate.

Step 2: Input Information

Enter the gathered information into the calculator’s fields:

  1. Gender: Select the appropriate option from the dropdown list.
  2. Age: Type your age into the provided field. The calculator requires age input to be between 18 and 120.
  3. Weight: Enter your weight in kilograms. Ensure the weight is within the allowed range of 20 to 300 kg.
  4. Serum Creatinine: Input the serum creatinine level in mg/dL, making sure the level is between 0.1 and 20.

Step 3: Calculate the Results

Once all inputs are filled correctly, activate the calculator to compute the results. It will automatically perform the following calculations:

  • Creatinine Clearance (Cockcroft-Gault): Provides an estimation of creatinine clearance using the Cockcroft-Gault formula. The result is displayed in mL/min.
  • Creatinine Clearance (normalized to 1.73 m² BSA): Adjusts creatinine clearance to a standard body surface area (BSA) of 1.73 m². The result is shown in mL/min/1.73m².
  • Renal Function Category: Categorizes renal function into different stages such as Normal, Mild Decrease, Moderate Decrease, Severe Decrease, or Kidney Failure based on the calculated clearance.

Step 4: Interpret the Results

Review the calculated outputs:

  • Check the Creatinine Clearance (Cockcroft-Gault) value for an overview of kidney function efficiency.
  • Consider the Creatinine Clearance normalized to BSA if you need an estimation adjusted for body size.
  • Use the Renal Function Category to understand the possible clinical relevance of the results in terms of kidney health status.

If the results indicate any levels of kidney impairment, it is advisable to consult with a healthcare professional for a detailed assessment and appropriate action.
