We directly tested 484 organisms from clinical (n  = 310) and simulated (n  = 174) positive blood cultures using the NG-Test Carba 5 assay for carbapenemase-producingEnterobacterales detection. The assay identified all but 4 of the KPC (170/171), OXA-48-like (22/22), VIM (19/21), and NDM (14/15) producers with no false positives.
