Recalls for Positive Blood Culture Identification And Ast Kit

Rare isolates of Enterobacteriaceae may generate a susceptible meropenem Minimum Inhibitory Concentration (MIC) using the affected device and a resistant result by broth microdilution. In order to mitigate any risk associated with these rare isolates, the firm has implemented an Expert Rule that suppresses the meropenem result for isolates that display a profile consistent with those that generated a false-susceptible result. The firm has responded to this risk by implementing a set of suppression rules, in a software update, to prevent incorrect results.

The kits may produce an elevated rate of false positive calls for the Staphylococcus aureus identification probe (SAU).
