Vancomycin Two-Level AUC

A transparent steady-state, one-compartment alternative when a validated Bayesian model is not being used—not a replacement for Bayesian software or local protocol.

Required model acknowledgement

Timing and model assumptions determine whether this result is usable.

This calculator requires two accurately timed post-distribution levels from the same steady-state interval, a stable dose and interval, and stable elimination. It is not valid for rapidly changing renal function, dialysis or other extracorporeal clearance, infusion overlap, undocumented doses, or samples taken during distribution.

  • This is first-order one-compartment estimation, not Bayesian forecasting.
  • The 400–600 AUC/MIC context applies to serious invasive MRSA infections with MIC assumed to be 1 mg/L; it is not a universal vancomycin target.
  • The calculator will not recommend a replacement dose or interval.

About this tool

Vancomycin AUC Calculator – Two Levels

Use this two-level vancomycin AUC calculator only when its steady-state, timing, and one-compartment assumptions fit the clinical situation and a validated Bayesian model is not being used.

The tool requires two accurately timed post-distribution levels from the same steady-state interval. It keeps model restrictions visible and does not automatically recommend a replacement regimen.
