Crcl Calculator

Step-by-Step Guide to Using the Creatinine Clearance (CrCl) Calculator

Step 1: Provide Patient’s Age

Begin by entering the patient’s age in years. Ensure the age entered is between 18 and 120 years, as this is required for a valid calculation. This field is a mandatory input.

Step 2: Select Patient’s Gender

Select the appropriate gender of the patient from the provided dropdown options. You can choose either “Male” or “Female.” This selection is essential to calculate the creatinine clearance accurately and is mandatory.

Step 3: Input Patient’s Weight

Enter the patient’s weight in kilograms. The acceptable range for weight input is between 20 kg and 300 kg. This field must be filled out and is a necessary component of the formula used to compute the result.

Step 4: Enter Serum Creatinine Level

Input the patient’s serum creatinine level in milligrams per deciliter (mg/dL). The valid range for this measurement is 0.1 to 20 mg/dL, and it should be input with precision to the tenths place as per provided step size (0.1). This field is required for calculation.

Step 5: Interpret the Results

• Creatinine Clearance (Cockcroft-Gault): The calculator will compute and display the creatinine clearance using the Cockcroft-Gault equation. This result will be formatted as a number with one decimal place and include the suffix “mL/min.”
• Renal Function Category: Based on the calculated creatinine clearance, the patient’s renal function is categorized into one of the following groups:
  • Normal: CrCl ≥ 90 mL/min
  • Mild Decrease: CrCl between 60 and 89 mL/min
  • Moderate Decrease: CrCl between 30 and 59 mL/min
  • Severe Decrease: CrCl between 15 and 29 mL/min
  • Kidney Failure: CrCl < 15 mL/min

Utilize this categorized information to better understand the patient’s renal status and take appropriate clinical actions.
