What is the normal creatinine clearance level for males?

The normal creatinine clearance level for males typically ranges from about 97 to 137 mL/min, with the average being around 107 mL/min. This measurement reflects the kidneys' ability to filter creatinine from the blood, which is a byproduct of muscle metabolism. A level above 107 mL/min indicates that the kidneys are functioning well within the standard range, suggesting effective renal clearance capabilities.

While the upper limit of normal can extend beyond this figure, particularly in very fit or muscular individuals, the answer of 107 mL/min is considered a key reference point for assessing kidney function in clinical settings. Levels significantly above this range may not be typical for all populations, which distinguishes this option as the most aligned with accepted clinical standards for the measurement in question.
