24-Hour Urine Creatinine Clearance Calculator
Calculate Creatinine Clearance (CrCl) from a 24-hour urine collection to assess kidney function.
Input Parameters
Enter details for calculation.
Creatinine Clearance
Expert Tip
Normal range: Male 97-137 mL/min, Female 88-128 mL/min. This directly measures clearance compared to estimated GFR.
Calculation Methodology & Details
Formula
1440 is the number of minutes in 24 hours. Calculates glomerular clearance capacity.
