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 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 organisms, or for epidemiological typing. The BC-GN test is performed on the Verigene System platform, which is a fully automated, bench-top, molecular diagnostics workstation consisting of Verigene Reader and a bank of up to 32 Verigene Processor SP units. The System enables the detection of bacterial DNA from blood culture, unformed stool, or nasopharyngeal swab, depending on the test, through automated nucleic acid extraction and hybridization.
