The LIAISON PLEX® Gram-Negative Blood Culture (BCN) Assay, performed using the automated, sample-to-result LIAISON PLEX® System, is a qualitative multiplexed in vitro diagnostic test for the simultaneous detection and identification of selected gram-negative pathogens and/or selected genetic determinants associated with antimicrobial resistance in positive blood culture bottles. LIAISON PLEX® BCN Assay is performed directly on blood culture media using blood culture bottles identified as positive by a continuous monitoring blood culture system which contain gram-negative bacteria as determined by Gram stain.

The LIAISON PLEX® BCN Assay detects and identifies the following:

Resistance Markers:

CTX-M (blaCTX-M)

IMP (blaIMP)

KPC (blaKPC)

NDM (blaNDM)

OXA (blaOXA)

VIM (blaVIM)

MCR

SME (blaSME)

Gram Negative Genera and Species:

Enterobacteriaceae / Morganellaceae

Acinetobacter baumannii

Acinetobacter spp.

Citrobacter spp.

Enterobacter spp. (1)

Escherichia coli (2)

Haemophilus influenzae

Klebsiella oxytoca

Klebsiella pneumoniae

Klebsiella variicola

Morganella morganii

Neisseria meningitidis

Proteus spp.

Pseudomonas aeruginosa

Pseudomonas spp.

Salmonella spp.

Serratia marcescens

Stenotrophomonas maltophilia

(1) Due to reclassification, Klebsiella aerogenes will be reported Enterobacter spp.

(2) LIAISON PLEX® BCN Assay will not distinguish between Escherichia coli and Shigella spp. (S. dysenteriae, S. boydii, S. flexneri and S. sonnei)

LIAISON PLEX® BCN Assay contains targets for the detection of genetic determinants associated with resistance to carbapenems (blaCTX-M, blaIMP, blaKPC, blaNDM, blaOXA48-like, blaVIM, blaSME) to aid in the identification of potentially antimicrobial-resistant organisms in positive blood culture samples. In addition, the panel includes an assay for the detection of the mobilized genetic determinant MCR, an emerging marker of public health importance. The antimicrobial resistance gene or marker detected may or may not be associated with the agent responsible for disease. Negative results for these select antimicrobial resistance gene and marker assays do not indicate susceptibility, as multiple mechanisms of resistance to ß-lactams and colistin exist.

LIAISON PLEX® BCN Assay is indicated for use in conjunction with other clinical and laboratory findings to aid in the diagnosis of bacterial bloodstream infections (BSI). LIAISON PLEX® BCN Assay is not intended to monitor treatment of 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 LIAISON PLEX® BCN Assay, to detect mixed infections that may not be detected by LIAISON PLEX® BCN Assay, for association of antimicrobial resistance marker genes to a specific organism, or for epidemiological typing.

Indications for use read by OCR from a scanned FDA summary, so letters may be misread. Check the PDF before quoting it.
