The next dimension in blood culture detection

VIRTUO Microbial Detection System, a fully automated blood culture solution with real-time notification of blood volume, quicker time to detection1 and virtually zero hands on time.

  • Flexibility to be placed where ever is the best for your workflow
  • Load & Go motion activated loading allows any trained skill level load the instrument
  • Smart scanning images the bottle to provide instant recognition of barcode labels and automated blood volume level detection
  • Meet the CAP standard MIC.22640 with 100% confidence with real-time notification alarms for over filled and under filled bottles
  • Precision robotics load and unload bottles automatically
  • Coupled with FAN® PLUS media and MYLA®, bioMérieux’s microbiology middleware solution, customers can maximize their efficiency and facilitate better patient outcomes


BACT/ALERT VIRTUO is the new standard in blood culture detection system from bioMérieux. The flexible platform fits into nearly any size lab, even outside the routine microbiology lab. With minimal training, the motion activated loading lets any skill level load the instrument. Just load bottles onto the motion activated loading bay and the bottles are automatically moved to a carousel and into the smart scanning station. The scanning station will rotate and image the bottle label and directly senses the blood fill level and records on every bottle in real time. The bottle is loaded and unloaded into newly designed racks by a robotic arm. High fidelity optics and new algorithms are incorporated to increase performance and time to detection. Advanced reporting is available with MYLA middleware providing a comprehensive view of microbiology workflow, instrumentation and quality indicators: Contamination rates, blood volume and time to detection. When used together, BACT/ALERT VIRTUO and FAN PLUS Media can help clinicians rapidly diagnose bloodstream infections to improve patient outcomes and to aid in Antimicrobial Stewardship.

Ultimate workflow efficiency

The VIRTUO system with its integrated features work together to provide a seamlessly efficient workflow. This new workflow maximizes efficiency and helps laboratorians provide more rapid results to physicians to impact patient care positively.
