  • Research summary

    The iFAST Antimicrobial Susceptibility Test (AST) System, manufactured by iFAST Diagnostics based in the UK, is an automated in vitro diagnostic system for quantitative and qualitative AST for most clinically significant Gram-negative aerobic microorganisms direct from positive blood cultures.

    The iFAST AST System is intended to be a safe and effective Quantitative and Qualitative test system, and the performance of the iFAST system will be assessed according to the standard ISO 20776-2:2022 Part 2: Evaluation of performance of antimicrobial susceptibility test devices against reference broth microdilution (BMD).

    To obtain UKCA Mark approval and to support claims that the system accurately performs both qualitative and quantitative antimicrobial susceptibility testing, the following will be evaluated:

    1. The iFAST AST system will be compared with the standard susceptibility methods that are used routinely in 3 typical UK hospital microbiology laboratories.

    2. Furthermore, per the ISO 20776-2:2022 standard, the iFAST results will be compared with a Broth Micro Dilution reference method performed by a central reference laboratory

    3. The evaluation will also assess the usability of iFAST and confirm its potential for delivering results within 3h of receiving a positive whole blood culture.
