Renal Clearance Calculator
Renal Clearance Calculator
Calculate renal clearance from urine and plasma drug concentrations
Clᵣ = (U × V) / P
U = urine concentration |
V = urine flow rate |
P = plasma concentration
Renal Clearance
0 mL/min
How Renal Clearance Is Calculated
Renal clearance represents the volume of plasma from which a substance is completely removed by the kidneys per unit of time.
The standard equation is: Clᵣ = (U × V) / P
The calculator converts the entered urine and plasma concentrations into compatible units and converts urine flow into mL/min before performing the calculation.
Educational use: This calculator is intended for
pharmacology and pharmacokinetics education. Clinical interpretation
should consider the specific drug, sampling conditions, renal
function, and the method used to measure concentrations.
