24 Hours Urine Creatinine Clearance Test
The 24 Hours Urine Creatinine Clearance test is a diagnostic laboratory test used to evaluate how effectively the kidneys are filtering waste from the blood. By measuring creatinine levels in both blood and urine collected over a 24-hour period, this test provides an estimate of the glomerular filtration rate (GFR), a key indicator of kidney function.
What This Test Measures
-
Creatinine concentration in urine collected over 24 hours
-
Blood creatinine level
-
Overall kidney filtration efficiency (creatinine clearance)
Why This Test Is Ordered
-
To assess kidney function and detect kidney disease
-
To monitor progression of chronic kidney conditions
-
To evaluate kidney performance before or during treatment
-
To help adjust medication dosages that are cleared by the kidneys
Sample Required
-
24-hour urine collection
-
Blood sample (usually taken once during the collection period)
Preparation & Instructions

-
Individuals with suspected or known kidney disease
-
Patients with diabetes, hypertension, or other conditions affecting kidney health
-
Those needing detailed kidney function assessment beyond routine blood tests
Turnaround Time
-
Results are typically available within 24–48 hours after sample submission
