Nanosphere, Inc.: The Verigene Gram-Positive Blood Culture Nucleic Acid Test (BC-UP) performed using the sample-to-result Verigene System is a qualitative, multiplexed in vitro diagnostic test for the simultaneous detection and identification of potentially pathogenic gram-positive bacteria which may cause bloodstream infection (BSI). BC-UP is performed directly on blood culture bottles identified as positive by a continuous monitoring blood culture system and which contain gram-positive bacteria. BC-UP detects and identifies the following bacterial genera and species: Staphylococcus spp., Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus lugdunensis, Enterococcus faecalis, Enterococcus faecium, Streptococcus spp., Streptococcus pneumoniae, Streptococcus pyogenes, Streptococcus agalactiae, Streptococcus anginosus, group and Listeria spp. In addition, BC-UP detects the mnecA resistance marker, inferring mecA-mediated, methicillin resistance, and the vanA and vanB resistance markers, inferring vanA/vanB-mediated vancomycin resistance. In mixed growth, BC-UP does not specifically attribute van-mediated vancomycin resistance to either E. faecalis or E. faecium, or mecA-mediated methicillin resistance to either S. aureus or S. epidermidis. BC-UP is indicated for use in conjunction with other clinical and laboratory findings to, aid in the diagnosis of bacterial bloodstream infections; however, is not to be used to, monitor these infections. Sub-culturing of positive blood cultures is necessary to recover, organisms for susceptibility testing, identification of organisms not detected by BC-UP, differentiation of mixed growth, association of antimicrobial resistance marker genes to a specific organism, or for epidemiological typing.

Root cause

Nonconforming Material/Component

Action

Nanosphere sent a Field Notification Letter dated October 10, 2013, to all affected customers. The letter identified the product, the problem and the action to be taken by the customer. Instructions were included in the letter for customers to determine whether or not the extraction tray lots should be returned. If the extraction tray lots are to be returned, customers were to complete and return the attached form and replacement tip holder assemblies will be supplied at no cost. Customers could then dispose of the recalled unused tip holder assemblies. Customers with questions were instructed to contact their Nanosphere technical support representative. For questions regarding this recall call 1-888-837-4436, ext 3.
