What is the clearance of a substance when its concentration in the plasma is 10 mg/dl, its concentration in the urine is 100 mg/dl & urine flow is 2 ml/min:
The Clearance of a Substance 'X' is equal to the concentration of substance X in urine (UX) times the urine flow per unit of time (V.) divided by the arterial plasma level of X (PX), or UXV./PX.
This value is called the clearance of X (CX).
