Event Description
A customer in (b)(6) contacted biomɒieux to report a misidentification of paracoccus sanguinis as brucella melitensis in association with the vitek 2 gn id test kit. Testing via maldi-tof did not provide an organism identification. The sample was a blood culture after colonoscopy from a patient with recurring fever after a long-term stay on (b)(6). Upon obtaining the result of brucella melitensis: the laboratory safely stored the strain. The laboratory staff (three persons) were treated same day with amphotericin sulbactam (ab) due to potential exposure to a select agent. The strain was sent to a reference laboratory for confirmatory testing; paracoccus sanguinis was identified by the reference laboratory (testing method unknown). No dna of brucella was found. The customer indicated the organism misidentification did not lead to any adverse event related to the patient's state of health; details regarding patient treatment were not provided by the customer. Additionally, the three laboratory personnel are showing no signs of adverse impact and remain in good health. As the strain is potentially a select agent, submission to biomerieux was not appropriate. Biomerieux internal investigation was conducted. The investigation concluded: paracoccus sanguinis is not a claimed species for the vitek 2 gn id card. When an isolate is tested in the gn id card, the gram negative knowledge base will attempt to match the reactions to known bio patterns stored in the knowledge base. If the reaction pattern of an unclaimed species is tested and match those in the knowledge base with a high degree of confidence, a misidentification can occur. The vitek 2 product information contains the following warning in the limitations section: "testing of unclaimed species may result in an unidentified result or a misidentification. " when an identification of brucella melitensis is reported by the gn id card, the system software prints the following message on the laboratory report: "important! presumptive identification. " a presumptive identification should always be confirmed with another method before reporting results. Review of complaint history for the last thirteen (13) month timeframe revealed one other complaint of a misidentification as brucella, and indicates the report was also due to testing of an unclaimed species (roseomonas rosea). The vitek 2 gn id test kit and associated knowledge base are performing as intended. Product labeling and software provide information to ensure additional attention for organism identifications of brucella melitensis.
