    Molecular Insights for Gastrointestinal (GI) Care

    Infectious gastroenteritis can be caused by a variety of bacterial, viral and parasitic organisms. Rapid and accurate diagnostic testing is essential to identify the infectious agent and guide the right treatment for patients.¹ 

    The Panther Fusion® GI Bacterial Assay supports informed clinical decision-making with differential diagnosis of the most common bacterial causes of acute diarrhea while seamlessly integrating into existing laboratory workflows.

    Superior Workflow2

    Valid rate of 97.8% after initial test and a 99.6% valid rate after retest,2 on a system with a large sample capacity, high throughput and minimal hands-on time.

    Sensitive and Specific2

    In a clinical trial evaluating over 1700 samples, The Panther Fusion GI Bacterial Assay showed a positive percent agreement (PPA) of more than 97% for all targets.2

    Customizable Flexible Panel

    Deliver only the results needed with customizable testing that simplifies diagnostic stewardship.

    Just a few Bacteria Account for Most Foodborne Illness in the United States3

    Other than Norovirus, Campylobacter, Salmonella and STEC are some of the leading causes of foodborne illness in the United States.

    Salmonella spp.

    1.28M cases per year 

    Among foodborne illnesses, Salmonella is the leading cause of death.3

    Campylobacter spp.

    1.87M cases per year

    Campylobacter is the most common bacterial cause of diarrheal illness in the United States.3

    Shigella spp.

    450,000 infections

    Antimicrobial-resistant Shigella infections result in an estimated $93 million in direct medical costs.⁵

    E. coli (STEC)

    265,000 cases per year

    STEC O157 causes about 36% of these cases, and non-O157 serogroups cause the rest of the cases.4

    More than gut instinct. Performance you can count on.

    The Panther Fusion® GI Bacterial Assay delivers rapid Multiplex real-time PCR detection of the most common bacterial causes of acute gastroenteritis. Deliver results that can enhance patient care and streamline laboratory workflows without adding needless complexity.

    Bacterial GI targets

    • Salmonella spp.
    • Shigella spp./EIEC
    • Campylobacter spp.
    • Shiga toxin (STEC)

    Part of a broad portfolio of molecular tests on a single platform, The Panther Fusion® GI Bacterial Assay can help support informed clinical decision-making and simplify stewardship programs. 

    Simple pre-analytical processing with Aptima® Multitest Tubes lets you run just one GI panel at a time or all at once without adding extra steps.

    Innovation never rests, and neither do we.

    Our GI portfolio is under development to bring the diagnostic power of Hologic to a wide range of gastrointestinal illnesses.
