What is Creatinine Clearance (24-hr Urine)?
Measures kidney filtration rate by comparing creatinine levels in blood and a 24-hour urine collection. More accurate than blood creatinine alone for assessing kidney function.
Why is this test important?
Provides the most accurate measurement of GFR. Essential for drug dosing in patients with kidney impairment. Useful when eGFR calculation may be inaccurate (muscle wasting, obesity).
How to Prepare
Collect all urine for 24 hours in the provided container. A blood sample is also needed.
