WebThere are three ways to calculate vancomycin clearance from levels (without the use of a population Vd model): 1) Two levels after the first dose, 2) a steady state peak and trough, or 3) three non-steady-state levels. Patients are often less stable when they first initiate vancomycin, so measuring two levels after the first dose may be unreliable.
