VERIGENE™ Gram-Negative Blood Culture Test

The VERIGENE® Gram-Negative Blood Culture Test (BC-GN) identifies genus, species, and genetic resistance determinants for a broad panel of gram-negative bacteria directly from positive blood culture bottles


While conventional microbiological methods may require 2-4 days to produce bacterial identification and resistance results, VERIGENE BC-GN provides results within two hours of blood culture positivity.

Intended Use

The VERIGENE Gram-Negative Blood Culture Nucleic Acid Test (BC-GN), performed using the sample-to-result VERIGENE System, is a qualitative, multiplexed in vitro diagnostic test for the simultaneous detection and identification of potentially pathogenic gram-negative bacteria which may cause bloodstream infection (BSI). BC-GN is performed directly on blood culture media using BACTEC™ Plus Aerobic/F, BACTEC™ Standard/10 Aerobic/F or BacT/ALERT SA Standard Aerobic blood culture bottles identified as positive by a continuous monitoring blood culture system and which contain gram-negative bacteria.

BC-GN independently detects and identifies the following Bacterial Genera and Species—Acinetobacter spp., Citrobacter spp., Enterobacter spp., Proteus spp., Escherichia coli1, Klebsiella pneumoniae, Klebsiella oxytoca, Pseudomonas aeruginosa, and Serratia marcescens— and Resistance Markers—CTX-M, KPC, NDM, VIM, IMP, and OXA.

BC-GN is indicated for use in conjunction with other clinical and laboratory findings to aid in the diagnosis of bacterial bloodstream infections; however, is not to be used to monitor these infections. Sub-culturing of positive blood cultures is necessary to recover organisms for susceptibility testing, identification of organisms not detected by BC-GN, differentiation of mixed growth, association of antimicrobial resistance marker genes to a specific organism, or for epidemiological typing.

  1. BC-GN will not distinguish Escherichia coli from Shigella spp. including S. dysenteriae, S. flexneri, S. boydii, and S. sonnei.
