Comparison of Target Detection Rates of Multiplex Gastrointestinal PCR Panels: A Systematic Literature Review & Meta-Analysis

Cepheid
18 Jun 2026

Multiplex gastrointestinal (GI) panels have transformed the detection of infectious gastroenteritis by enabling rapid identification of multiple pathogens from a single test. However, broader panels can introduce challenges, including detection of non-clinically relevant organisms, increased diagnostic uncertainty, and potential overtreatment.

Developed by Cepheid and presented at IDWeek 2025, this scientific poster explores how targeted multiplex GI panel design can improve diagnostic confidence while supporting antimicrobial stewardship. Discover how targeted multiplex GI panel design can improve diagnostic confidence, support antimicrobial stewardship, and optimize laboratory efficiency.

Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Diagnostic tests include bacterial culture, microscopy, chemistry assays, molecular diagnostics and MALDI-TOF. Tests can be carried out in the laboratory or at the point-of-care.
