Siemens Recalls MicroScan Synergies Plus® And RapID/S Plus Gram Negative Panels

Siemens Healthcare Diagnostics (NYSE:SI) has issued a voluntary recall of its MicroScan Synergies plus ® Negative and rapID/S plus Negative panels. These panels are used for determining antimicrobial susceptibility and/or identification for gram-negative bacteria. An internal investigation has confirmed an increase in false susceptible and false intermediate misreads for imipenem and/or meropenem when read rapidly (< 16 hours) on the MicroScan ® WalkAway Microbiology System¹. The investigation determined that no other antimicrobial agent results are affected. Siemens has notified the FDA of this action.

This defect could potentially lead to misclassification of a resistant or partially resistant strain of gram negative bacteria which may result in treatment with an inappropriate antibiotic or a delay in initiating appropriate therapy. As a result of these findings, Siemens has issued a voluntarily recall for MicroScan Synergies plus Negative and rapID/S plus Negative panels shipped from June 2011 through August 2013. This issue is not panel lot specific or related to a particular WalkAway instrument model. Dried Overnight Gram Negative Panels are not impacted by the issue.
