The polymyxins are important antimicrobial agents against antibiotic-resistant gram-negative *** 2020,the Clinical and Laboratory Standards Institute modified the clinical breakpoints for polymyxin susceptibility test by eliminating the"susceptible"interpretive category,only reporting intermediate(≤2 mg/L)and resistant(≥4 mg/L).However,the European committee on antimicrobial susceptibility testing recommended the use of clinical breakpoints of W2 mg/L as susceptible and>2 mg/L as *** first-line laboratorians and clinicians in China have been perplexed by the inconsistence of international polymyxin clinical breakpoints and discouraged by the difficulty of conducting polymyxin susceptibility ***,it is urgently needed to make it clear for the laboratorians in China to know how to accurately carry out polymyxin susceptibility testing and standardize the interpretation of susceptibility testing *** this end,the experts from relevant fields were convened to formulate this consensus statement on the testing and clinical interpretation of polymyxin *** recommendations are proposed accordingly for laboratorians and clinicians to streamline their daily work.
