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 selected gram-negative bacteria and resistance markers. BC-GN is performed directly on blood culture media using blood culture bottles identified as positive by a continuous monitoring blood culture system and which contain gram-negative bacteria as determined by Gram stain.

BC-GN detects and identifies the following Bacterial Genera and Species—Acinetobacter spp., Citrobacter spp., Enterobacter spp., Proteus spp., Escherichia coli1, Klebsiella pneumoniae, Klebsiella oxytoca, and Pseudomonas aeruginosa— and Resistance Markers—CTX-M (blaCTX-M), KPC (blaKPC), NDM (blaNDM), VIM (blaVIM), IMP (blaIMP), and OXA (blaOXA).

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 used to monitor these infections. Sub-culturing of positive blood cultures is necessary to recover organisms for antimicrobial susceptibility testing (AST), for identification of organisms not detected by BC-GN, to detect mixed infections that may not be detected by BC-GN, for 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. (S. dysenteriae, S. flexneri, S. boydii, and S. sonnei).
