Data set for Kamau et al. Evaluation of VITEK® REVEAL^TM Fast AST System vs. VITEK® 2 for Antimicrobial Susceptibility Testing of Gram-negative Bacteria from Positive Blood Cultures Lauren Naatz (24489119) Medical bacteriology Gram-negative bacteria bloodstream infection fast antimicrobial susceptibility testing VITEK REVEAL VITEK 2 phenotypic AST time to result <p dir="ltr">This study compared the VITEK® REVEAL^TM fast AST system for direct testing from positive blood cultures (PBCs) with the standard-of-care VITEK® 2.A total of 250 prospectively collected PBC bottles containing monomicrobial Gram-negative organisms were assessed. AST was performed using VITEK® REVEAL^TM directly from PBC and VITEK® 2 from isolated colonies recovered from the PBC. Essential agreement (EA), categorical agreement (CA), and discrepancy rates were calculated. Time to result (TTR) was also recorded. When compared to VITEK® 2, VITEK® REVEAL^TM demonstrated EA of 97.51% and CA of 94.83% across 4,180 organism–antimicrobial comparisons with agreement exceeding 95% for most antimicrobials. When evaluating instrument run time (not inclusive of the 18-24 h subculture times), the REVEAL^TM reported final results approximately 4 hours sooner than VITEK® 2 (median 8.0 h vs 11.9 h). REVEAL^TM reported final results for resistant isolates faster than susceptible or intermediate isolates (median 5.4 h vs 6.5 h). VITEK® REVEAL^TM provides fast, accurate phenotypic AST directly from positive blood cultures comprising monomicrobial Gram-negative organisms and complements VITEK® 2 by accelerating early susceptibility reporting.</p> 2026-09-15T19:46:45Z Dataset Dataset 10.6084/m9.figshare.33819883.v1 https://figshare.com/articles/dataset/Data_set_for_Kamau_et_al_Evaluation_of_VITEK_REVEAL_sup_TM_sup_Fast_AST_System_vs_VITEK_2_for_Antimicrobial_Susceptibility_Testing_of_Gram-negative_Bacteria_from_Positive_Blood_Cultures/33819883 CC BY 4.0
