Final answer:
Creatinine clearance is reported in units of mL/min. This measurement reflects the kidney's ability to clear creatinine from the bloodstream and is an important indicator of renal function.
Step-by-step explanation:
The correct answer to the question is d. mL/min. Creatinine clearance is reported in units of milliliters per minute (mL/min), which reflects the volume of blood plasma that is cleared of creatinine by the kidneys per minute. The creatinine clearance test is a measure of the glomerular filtration rate (GFR), indicating how well the kidneys are filtering wastes from the blood. A typical range for normal creatinine clearance, which can be age-dependent, is 90-139 mL/min for adult males less than 40 years old and 80-125 mL/min for adult females less than 40 years old.
For calculating creatinine clearance (CCr), you need the creatinine concentration in urine (U), the urine flow rate (V), and the creatinine concentration (B) in plasma. The formula is given as UxV/B. To make comparisons consistent among individual physical differences, the creatinine clearance is often adjusted for body surface area (BSA) and reported as mL/min/1.73 m².
