BACT/ALERT VIRTUORecalls & reported problems across all models

We found 2 models of BACT/ALERT VIRTUO by Biomerieux , Inc. in the FDA's device registry (GUDID). Together they are named in 41 adverse event reports in the FDA's MAUDE database, received between Dec 13, 2017 and May 21, 2026 — classified as 2 injuries, 39 malfunctions.

The most frequently reported specific device problem is “False Negative Result” (7 reports).

2 FDA recall records name at least one of these models by its device identifier.

Reports come from manufacturers, hospitals and patients and are not verified by the FDA. A report does not prove the device caused the event. Widely used products collect more reports, so totals can't be used to compare products or estimate failure rates. Only reports that name a model's exact device identifier are counted.

   The BACT/ALERT VIRTUO Instrument Firmware version R2.0 allows relocation of the four (4) resident calibration standards so that Field System Engineers (FSE) can service the associated cells P24 - P27, where the calibration standards typically reside. If the calibration standards are not returned to the designated locations, an anomaly may occur.
