What Gram-Negative Species Is It?

Why you need to know the difference

Gram-negative bloodstream infections (BSI) are associated with high mortality rates and can be difficult to treat due to increasing resistance to antimicrobial agents, especially for Pseudomonas aeruginosa. Patients with Gram-negative BSI are either subjected to broader-than-necessary antimicrobial therapy that can lead to subsequent infections with multi-drug resistant pathogens and the risk of toxicity complications, or are undertreated, increasing the risk for adverse patient outcomes.1

QuickFISH Provides 20 Minute Identification and Differentiation of Gram-negative Species

  • Results 1-3 days earlier than conventional methods.
  • Allows for early, aggressive and appropriate therapy for patients with P. aeruginosa or another Gram-negative species such as E. coli or K. pneumoniae.
  • Provide clinicians with timely information necessary to match antibiotics to organisms in the critical first hours of infection.
