The Impact of a Rapid Blood Culture Identification System on a Pediatric Institution

Although automated blood systems can save time, subcultures are required for growth of the organism, specific biochemical testing, assays for the identification of potential pathogens and antimicrobial susceptibility testing. Pediatric blood cultures present unique problems such as fastidious organisms, antimicrobial treatment and small specimen volumes. Furthermore, contamination of blood cultures by skin microbiota such as coagulase-negative Staphylococci may be problematic in specific populations such as immunocompromised patients where determining true pathogens can be more difficult.

GenMark’s ePlex® System is a molecular amplification and identification system with three panels for the identification of organisms causing bloodstream infections and certain associated antibiotic resistance genes. To aid in reducing the time to identification of key pathogens, resistances and possible contaminants, the ePlex® Blood Culture Identification (BCID) Panels are fully automated sample-to-answer PCR-based assays designed to identify gram-positive and gram-negative bacteria, fungi and bacterial resistance genes in approximately 90 minutes from positive blood culture.


Automated identification platforms for the identification of bacterial and fungal pathogens from positive blood cultures have revolutionized the process for treating these important infections. The BCID panels have the most comprehensive list of potential pathogens and contaminants of any system available and include several unique pediatric pathogens including Neisseria meningitidis and Haemophilus influenzae.

The use of the blood culture identification system achieves its maximum laboratory and clinical value when fully integrated into the laboratory information system, the hospital clinical care systems and Antimicrobial Stewardship Programs. Full integration can improve workflow, information flow and revolutionize patient care through the identification of important pathogenic bacteria and fungi, contaminating bacteria and key antimicrobial resistance markers.

In addition, given the importance of identifying pathogens and associated resistance in normally sterile body site (NSBS) samples, there are ongoing studies to examine the off-label use of the ePlex system for faster identification from these specimens. This webinar will also highlight some preliminary research use only (RUO) data looking at a variety of NSBS specimens tested using the BCID Panels.
