LIAISON PLEX® Gram-Positive Blood Culture Assay
Optimize Treatment in Hours—Not Days
The LIAISON PLEX® Gram-Positive Blood Culture Assay integrates with your standard-of-care workflow for maximum clinical impact through the molecular detection and differentiation of 17 targets including 13 gram-positive bacteria frequently found to cause bacteremia, plus 4 resistance genes associated with these bacteria.
Disease state
Sepsis is the leading cause of mortality in U.S. hospitals, with over 1.7 million cases diagnosed annually.1 Delays in optimal treatment significantly increase the risk of mortality, with estimates indicating a 7.6% rise in fatality rates for each hour of delay.2 The financial burden of acute sepsis hospitalization is substantial, with annual costs estimated at $62 billion.3
Gram-positive bacteremia accounts for approximately 60% of all positive blood cultures. Invasive gram-positive bacteremia often requires therapeutic adjustments from more generalized empiric therapy.4

Sepsis is a disease associated with high mortality.
The value of LIAISON PLEX® Gram-Positive Blood Culture Assay
Empower clinicians to rapidly optimize treatment for gram-positive bacteremia.
Clinical impact
Comprehensive pathogen and resistance gene coverage enhances diagnostic accuracy, empowering informed decisions to optimize patient management while also reinforcing antimicrobial stewardship—ultimately aiding in the fight against bloodstream infections and sepsis.
Outstanding economic value
Designed for seamless workflow integration, the Gram stain-based panel selection enhances diagnostic stewardship while optimizing operational costs.
The right assay design
Non-amplified molecular chemistry helps minimize false results that may occur with PCR-based amplification of non-viable DNA in blood culture media.
How the LIAISON PLEX® Gram-Positive Blood Culture Assay works
LIAISON PLEX® Gram-Positive Blood Culture Assay is a syndromic in vitro diagnostic test for the detection and identification of invasive pathogenic gram-positive bacteria. Subculturing is necessary for the identification and susceptibility testing of organisms not detected by the assay, in conjunction with standard of care culture workflows.
