Creatinine clearance test measures kidney function by assessing which organ?

Creatinine clearance gauges how well the kidneys filter waste from the blood. It measures how much creatinine is removed into the urine over a set period (often 24 hours) by comparing urine creatinine with plasma creatinine. The organ involved is the kidney, since it’s responsible for filtering blood and producing urine; the liver, heart, and lungs do not perform this waste clearance. In practice, the calculation uses the urine creatinine concentration, the total urine volume, and the plasma creatinine concentration to estimate renal filtration capacity, which is why this test is a direct measure of kidney function.
