Radian®
Automated Disk Diffusion Set up and Interpretation
Product Overview
Radian® is a fully integrated solution that automates the seeding of Mueller Hinton plates, application of antibiotic discs, transfer of prepared agar plates to incubators, plate imaging, zone measurement, zone interpretation, and result output using the Halo Recognition Algorithms, part of the Radian® Expert System AI.
- Automatic McFarland suspension seeding
- Customizable antibiotic disk application
- Automated zone size reading and interpretation using CLSI Rules
Disk diffusion testing has been a mainstay of laboratory methods for susceptibility testing, but despite its low cost, requires manual intervention for set up and reading. The Radian® system is the first of this kind that offers a fully automated and integrated system for disk diffusion testing.
Streamline AST Workflow
Radian® delivers major workflow efficiencies, freeing staff for higher value tasks while expediting results.1, 3-10
Ensure Standardized Best Practices
Radian® automatically applies standards and enables laboratories to configure their own interpretation rules, ensuring consistent results. 2,10
Maximize Traceability Across Platforms
Integrating WASPLab® and Radian® with your LIS ensures comprehensive data traceability, aiding daily routines.
Improve AST Turnaround Time
When validated by the laboratory, Radian® has the potential of early susceptibility reading, allowing for more timely results.1, 2-4, 6-8
Increases Productivity While decreasing Operational Cost
The Radian® system is the first of this kind that offers a fully automated and integrated system for disk diffusion testing. Starting with the creation of McFarland suspensions, Meuller Hinton agar plates are then automatically seeded and susceptibility disks applied. Radian® increases productivity, allowing laboratory staff more time to manage their ever-increasing workload.2, 5, 10
Unmatched Flexibility and Customization
Radian® is a flexible antimicrobial susceptibility testing (AST) platform that can be used with many types of antimicrobial disks. Radian’s high-capacity antimicrobial carousel allows users to select from up to 50 antibiotics for protocols using up to 6-8 discs per 100mm plate.
Fully Automate, Digitally Read and Interpret AST Results
Radian® can be retrofitted onto most existing WASPLab® platforms, taking advantage of the WASPLab® telecentric high-definition camera. Digital interpretations are made with the specialized imaging capabilities in combination with Halo Recognition Algorithms (to measure zone diameters) used by Radian® Expert System.
Streamlining AST workflow using automation and AI allows for standardization, labor savings, and improved turnaround time. When validated by the laboratory, Radian® has the potential of early susceptibility reading for more timely results.1, 2-4, 6-8
Radian® Expert System
Through the easy and intuitive graphic interface, the operator has all the specimen’s data at their fingertips and can customize Radian® Expert System interpretation rules autonomously. The flexible, customizable, and user-friendly platform interprets susceptible, intermediate, or resistant results. Digital interpretations are made with the specialized imaging capabilities in combination with Halo Recognition Algorithms used by Radian® Expert System in the WASPLab® software.
