Creatinine clearance is a test that requires the collection of urine for 24 hours. It measures how well the kidneys are filtering waste from the blood. The other options listed do not require a 24-hour urine collection. A clean catch specimen is urine collected midstream to avoid contamination. Blood urea nitrogen measures the amount of nitrogen in the blood that comes from urea, a waste product of protein metabolism. Culture and sensitivity involves testing a sample of urine to identify any bacteria present and determine which antibiotics will be most effective for treatment.
