WARNING against colistin gradient tests The EUCAST Development Laboratory, together with several EUCAST Network Laboratories, have investigated the ability of current gradient tests (Etest and MTS) to accurately predict colistin MIC values. Both gradient tests underestimate the MIC-values, especially on and above the breakpoint of 2 mg/mL, leading to false susceptibility. 2016/07/07
