Creatinine Clearance Calculator (24-Hour Urine Method) for Mild Kidney Impairment
Example values for a patient with mildly elevated serum creatinine suggesting reduced kidney function.
Calculates creatinine clearance in mL/min using the 24-hour urine collection method. Enter your Urine Creatinine Concentration, Total Urine Volume, Serum Creatinine, Collection Time to get an instant creatinine clearance (ml/min). Formula: (urine_creatinine * urine_volume) / (serum_creatinine * collection_time).

How It Works
How It Works
This calculator measures how well your kidneys are clearing creatinine from your blood using a 24-hour urine collection. It compares the amount of creatinine in your urine to the amount in your blood over a specific time period.
The formula multiplies urine creatinine by total urine volume, then divides that result by serum creatinine multiplied by collection time. This provides a clearance rate in milliliters per minute (mL/min).
- Enter urine creatinine concentration (mg/dL)
- Enter total urine volume collected (mL)
- Enter serum creatinine level (mg/dL)
- Enter total collection time (minutes)
Understanding the Results
The result shows how many milliliters of blood are cleared of creatinine each minute. Higher values usually indicate better kidney filtration, while lower values may suggest reduced kidney function.
Results should always be interpreted by a healthcare provider, as normal ranges can vary based on age, sex, and body size.
- Reported in mL per minute (mL/min)
- Higher values generally reflect better kidney filtration
- Lower values may indicate decreased kidney function
- Discuss results with a healthcare professional for proper evaluation
