System Overview

BACT/ALERT® VIRTUO® ushers in a new dimension of blood culture detection. The system provides fully automated detection of the presence of microbes in bottles of blood and sterile body fluids. Almost endlessly versatile, BACT/ALERT® VIRTUO® fits into various lab sizes and types, including labs outside the routine microbiology lab. The latest example of ingenuity in automation, it reduces hands-on time for increased lab efficiency. These benefits can be further boosted through highly sophisticated MAESTRIA™ software that provides relevant information from multiple instruments and your LIS at your fingertips, when and where you need it. For these reasons and more, BACT/ALERT® VIRTUO® seamlessly integrates your blood culture workflow to provide efficient and actionable results to help you achieve better patient outcomes.

  • Automated efficiency: leverage skilled resources where most valuable
  • Fast results: thermal stability & ultra-sensitive algorithms shorten time to positivity
  • Modular for various lab sizes: scalable to meet your volume needs
  • Real-time blood level detection: act immediately & monitor collection practices
  • Active monitoring: receive real-time notifications & data


Ultimate Workflow Efficiency

Your laboratory faces some critical challenges these days: higher volumes, the need for fast turnaround time and the need to use staff resources effectively. Clinicians and their patients count on you meeting these challenges. The intelligent automation of BACT/ALERT® VIRTUO® ensures your workflow couldn’t be easier.
