What is the normal creatinine clearance range for healthy men?

1. 80-120 mL/min

2. 88-128 mL/min

3. 97-137 mL/min

4. 100-140 mL/min

The correct answer is: 97-137 mL/min

The normal creatinine clearance range for healthy men typically falls within the range of 97 to 137 mL/min. This measurement reflects the kidney's ability to filter creatinine, a waste product from muscle metabolism, from the blood. Maintaining a clear range for creatinine clearance is essential in assessing renal function, as it provides insight into the kidneys' effectiveness in filtering out nitrogenous waste. Values outside this range can indicate abnormal kidney function. A clearance rate lower than normal suggests impaired renal function and potential issues such as kidney disease, while a rate consistently above this range could also suggest hyperfiltration or other renal abnormalities. Recognizing the range of 97 to 137 mL/min as normal for healthy men helps radiographers and other healthcare providers interpret lab results accurately, particularly when evaluating patients for procedures that may impact renal function, such as those involving contrast media.
