Webfunction. A healthy kidney should yield a clearance rate for creatinine and thus a GFR of 97 to 137 ml/min for a male, and 88 to 128 ml/min for a female. Thus, if we apply this concept of clearance and GFR to other substances processed by the kidneys we could use these values to determine: How the kidneys handle the particular substance. If the The kidney's ability to perform many of its functions depends on the three fundamental functions of filtration, reabsorption, and secretion, whose sum is called renal clearance or renal excretion.
