Recall – Erroneous result from automated lab test system due to software error

Company: Biomerieux Inc
Date of Enforcement Report: 3/31/2021
Class II


VITEK 2 (version numbers 8.01, 8.02 (8.0x) and 9.01, 9.02 (9.0x) with the external communication configured to HL7 (system, test, automated, antimicrobial susceptibility, short incubation). VITEK 2 is an automated system consisting of instruments, software and reagent cards designed for the identification and antimicrobial susceptibility testing of bacteria and yeast. The VITEK 2 utilizes growth-based biochemical patterns to determine identification. The VITEK 2 provides minimal inhibitory concentration (MIC) results for most organism/drug combinations as well as a category interpretation (S, I, or R) consistent with accepted criteria.

Recall Number: Z-1307-2021


Biomerieux has identified a potential safety risk worst case of a false susceptible erroneous test result associated with this event. The problem is when HL7 Connection is used, the results in the VITEK 2 do not match the results sent to the LIS and the Laboratory Technician would need to change results in the LIS to match those in the VITEK 2. If the isolate is sent more than once to LIS, a software defect prevents the system from sending the expertised interpretation results and the Therapeutic Corrections (TC) is not sent to Laboratory Information Systems (LIS).


Biomerieux Inc. on 1/28/2021. Voluntary:  Firm Initiated recall is ongoing.
