Laboratory Specialists, Inc. (LSI) provides susceptibility testing of new antimicrobial agents for clinical microbiology laboratories (list of agents is shown below). If there are other agents not included on our current list, please contact us to inquire about the possibility of testing in the future. This AST service is either funded by pharmaceutical companies in support of their specific antimicrobial agents or available as a fee-based test. All testing is performed with MIC frozen panels according to CLSI reference broth microdilution testing (1, 2), unless otherwise stated. A set of quality assurance isolates with known MICs are used to validate each lot of MIC panels. Quality control testing, with at least one CLSI recommended QC strain, is included on each day of testing. In addition, proficiency strains are tested twice a year utilizing the PASS proficiency program (MicroTech Laboratories, Westlake, OH) that is designed to test new agents not yet available with other proficiency programs.
To submit an isolate for MIC testing download the submission form,
