  Vergene Amplification Tray - 700uL, BC-GP REF 20-011-018 The Verigene(R) Gram-Positive Blood Culture Nucleic Acid Test (BC-GP) 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-GP is performed directly on blood culture bottles identified as positive by a continuous monitoring blood culture system and which contain gram-positive bacteria.

  Great Basin Staph lD/R Blood Culture Panel The Great Basin Staph lD/R Blood Culture Panel is a qualitative, multiplex in vitro diagnostic assay intended for use with the P4500 PortraitrM Analyzer System. The Staph lD/R Blood Culture Panel is capable of simultaneous detection and identification ol Staphylococcus aureus, Staphylococcus epidermidis, Staphylococcus lugdunensrs and various Staphylococcus species to the genus level and the detection of the mecA gene for methicillin resistance from patient positive blood culture specimens.

  The Great Basin Staph ID/R Panel is being recalled because the S. aureus probe could potentially result in a false positive.

  Verigene BC-GP Kit (Catalog number 20-005-018); 1) 20 Verigene BC-GP Test Cartridges; are qualitative multiplexed in vitro diagnostic tests for simultaneous detection and identification of selected gram-positive (BC-GP) and gram-negative (BC-GN) bacteria and resistance markers.

  There is a specific Extraction Tray lot containing Tips that may slightly increase the occurrence of Process SP Processing Error when used due to the Processor SP experiencing difficulty releasing the Tip to the final location in the Tip Assembly. The difficult releasing the Tip can result in a Processing Error and occasionally the Tip to be dropped into the Processor SP.

  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.

  Nanosphere has received several reports relating to an increased rate of Processing Errors during procedures performed on the Processor SP caused by Tips in Tip Holder Assemblies for the following products and lots of Extraction Trays.

  FirmArray Blood Culture Identification (BCID) Panel, Model 2.0 The FilmArray Blood Culture Identification (BCID) Panel is a qualitative multiplexed nucleic acid-based in vitro diagnostic test designed to test positive blood cultures to quickly identify the organism that is growing in the blood culture. The following gram-positive bacteria, gram-negative bacteria, and yeast are identified using the FilmArray BCID Panel: Enterococci, Listeria monocytogenes, commonly encountered Staphylococci (including specific differentiation of Staphylococcus aureus), commonly encountered Streptococci (with specific differentiation of Streptococcus agalactiae, Streptococcus pneumoniae, and Streptococcus pyogenes), Acinetobacter baumannii, commonly encountered Enterobacteriaceae (including specific differentiation of the Enterobacter cloacae complex, Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae, Proteus, and Serratia marcescens), Haemophilus influenzae, Neisseria meningitidis (encapsulated), Pseudomonas aeruginosa, Candida albicans, Candida glabrata, Candida krusei, Candida parapsilosis, and Candida tropicalis. The FilmArray BCID Panel also contains assays for the detection of genetic determinants of resistance to methicillin (mecA), vancomycin (vanA and vanB), and carbapenems (blaKPC) to aid in the identification of potentially antimicrobialresistant organisms in positive blood culture samples.

  BioFire has identified an increased risk of false positive results when the FilmArray Blood Culture Identification (BCID) Panel is used with bioMrieux BacT/ALERT Standard Anaerobic (SN) blood culture bottles. False positive results have been observed for Pseudomonas aeruginosa and Enterococcus.

  Verigene Processor SP, Model Numbers 10-0000-07 and 10-0000-07R. Used with assay: Luminex, VERIGENE Gram-Positive Blood Culture Nucleic Acid Test,BC-GP, IVD - Product Usage: IVD sample processor, which utilizes a single-use disposable test consumable and a self-contained Verigene Test Cartridge for each sample tested.

  Luminex has determined that three (3) separate test fixtures used by field service engineers to service the VERIGENE SP Processors were procured from unapproved sources and, in some cases, were manufactured using unvalidated processes. These text fixtures were used to calibrate and verify VERIGENESP devices.
