“Antimicrobial resistance is a global health emergency that will seriously jeopardize progress in modern medicine.” - Dr. Tedros Adhanom Ghebreyesus, Director General, WHO. 

Thermo Scientific products for antimicrobial susceptibility testing (AST) can help clinicians, veterinarians, food scientists, and public health officials determine pathogen antimicrobial susceptibility patterns while supporting global and regional antimicrobial stewardship. From manual disc diffusion to automated instrumentation with true minimum inhibitory concentration (MIC) results, our powerful, comprehensive testing solutions help you achieve accurate, reliable, consistent results and optimized workflows.

 

The Thermo Scientific Sensititre System lets you combine manual, semi-automated, and fully automated tests within a single integrated AST platform using broth microdilution (BMD), the gold standard for AST accuracy.¹ With over 300 antimicrobials available, including the latest on the market, on both standard and customizable MIC plates, the Sensititre System allows you to consolidate confirmatory tests while meeting FDA, CLSI, and EUCAST breakpoint requirements.

Helping laboratories address the growing global challenge of antimicrobial resistance (AMR)

In this video, experts from Thermo Fisher Scientific discuss how innovation in antimicrobial susceptibility testing (AST) is helping laboratories address the growing global challenge of antimicrobial resistance (AMR). Recorded at ESCMID Global 2026, the conversation explores the latest resistance trends, the importance of continuously evolving AST panels, and how collaboration, automation, and scientific innovation are shaping the future of microbiology.

 

As antimicrobial resistance continues to evolve, laboratories need AST solutions that keep pace with emerging pathogens and newly approved therapies. Discover how Thermo Scientific Sensititre custom panels and next-generation Gram-negative (GN) panels provide the flexibility, clinical relevance, and up-to-date antimicrobial coverage needed to support confident treatment decisions and effective antimicrobial stewardship.

Guiding treatment decisions for the critically ill- when is a true MIC not a true MIC?

Without accurate, actionable minimum inhibitory concentration (MIC) data, clinicians may be working in the dark – but despite the MIC result’s significant potential impact on patient care, there is still uncertainty around the best way to generate it. Download our latest white paper to hear directly from the experts on the impact of definitive MIC results on therapeutic treatment decisions and patient care.

Explore our wide range of standard MIC plates and antimicrobials

Choose from our comprehensive selection of standard MIC plates for Gram positive, Gram negative, yeast and fastidious organisms, as well as veterinary and surveillance plates. Or, design your own custom plate tailored to your formulary. Our latest Sensititre Plate Guide includes everything you need to get to know the Sensititre System.
