Renal clearance uses the rate at which a compound is “cleared” from the body, i.e., is excreted in the urine, to determine aspects of renal function. The practical aspect of the clearance principle is that by applying it to select compounds, one can estimate glomerular filtration rate and renal plasma flow. powerbilt persimmon woods
