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 Enteric Pathogens Nucleic Acid Test (EP) is a multiplexed, qualitative test for simultaneous detection and identification of common pathogenic enteric bacteria and genetic virulence markers from liquid or soft stool preserved in Cary-Blair media, collected from individuals with signs and symptoms of gastrointestinal infection. The test is performed on the automated Nanosphere Verigene System utilizing reverse transcription (RT), polymerase chain reaction (PCR), and array hybridization to detect specific gastrointestinal microbial nucleic acid gene sequences associated with the following pathogenic bacteria: - Campylobacter Group (comprised of C. coli, C. jejuni, and C. lari), - Salmonella species, - Shigella species (including S. dysenteriae, S. boydii, S. sonnei, and S. flexneri), - Vibrio Group (comprised of V. cholerae and V. parahaemolyticus), - Yersinia enterocolitica. In addition, EP detects the Shiga toxin 1 gene and Shiga toxin 2 gene virulence markers. Shiga toxin producing E. coli (STEC) typically harbor one or both genes that encode for Shiga Toxins 1 and 2. EP is indicated as an aid in the diagnosis of specific agents of gastrointestinal illness, in conjunction with other clinical, laboratory, and epidemiological information; however, is not to be used to monitor these infections. EP also aids in the detection and identification of acute gastroenteritis in the context of outbreaks. Due to the limited number of positive specimens collected for certain organisms during the prospective clinical study, performance characteristics for Yersinia enterocolitica, Vibrio Group and Shigella species were primarily established with contrived specimens. Concomitant culture is necessary for organism recovery and further typing of bacterial agents. EP results should not be used as the sole basis for diagnosis, treatment, or other patient management decisions. Confirmed positive results do not rule out co-infection with other organisms that are not detected by this test, and may not be the sole or definitive cause of patient illness. Negative EP results in the setting of clinical illness compatible with gastroenteritis may be due to infection by pathogens that are not detected by this test or non-infectious causes such as ulcerative colitis, irritable bowel syndrome, or Crohn's disease.

The Verigene Respiratory Virus Plus Nucleic Acid Test (RV+) on the Verigene System is a qualitative nucleic acid multiplex test intended to simultaneously detect and identify multiple respiratory virus nucleic acids in nasopharyngeal (NP) swab specimens from individuals with signs and symptoms of respiratory tract infection. The following virus types and subtypes are identified using the RV+: Influenza A, Influenza A subtype H1, Influenza A subtype H3, 2009 H1N1, Influenza B, Respiratory Syncytial Virus (RSV) subtype A, and RSV subtype B. The test is not intended to detect Influenza C virus. Detecting and identifying specific viral nucleic acids from individuals exhibiting signs and symptoms of respiratory infection aids in the diagnosis of respiratory viral infection, if used in conjunction with other clinical and laboratory findings. Negative results for Influenza A, Influenza B, or RSV do not preclude influenza virus or RSV infection and should not be used as the sole basis for diagnosis, treatment, or patient management decisions. Conversely, positive results do not rule-out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease. The use of additional laboratory testing and clinical presentation must be considered in order to obtain the final diagnosis of respiratory viral infection. Performance characteristics for Influenza A Virus were established when Influenza A/H3, A/H1, and 2009 H1N1 were the predominant Influenza A viruses circulating. These characteristics may vary when other Influenza A viruses are emerging. If infection with a novel Influenza A virus is suspected based on current clinical and epidemiological screening criteria recommended by public health authorities, specimens should be collected with appropriate infection control precautions used specifically for novel virulent influenza viruses and sent to state or local health department for testing. Viral culture should not be attempted in these cases unless a BSL 3+ facility is available to receive and culture specimens.

The Verigene Clostridium difficile Nucleic Acid Test (CDF) is a qualitative, multiplexed in vitro diagnostic test for the rapid detection of toxin A (tcdA), toxin B (tcdB), and tcdC gene sequences of toxigenic strains Clostridium difficile and for presumptive identification of PCR ribotype 027 strains from unformed (liquid or soft) stool specimens collected from patients suspected of having C. difficile infection (CDI). Presumptive identification of the PCR ribotype 027 strain of C. difficile is by detection of the binary toxin (cdt) gene sequence and the single base pair deletion at nucleotide 117 in the tcdC gene. The tcdC gene encodes for a negative regulator in C. difficile toxin production. The test is performed on the Verigene System and utilizes automated specimen preparation and polymerase chain reaction (PCR) amplification, combined with a nanoparticle-based array hybridization assay to detect the toxin gene sequences associated with toxin-producing C. difficile.

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.

BC-GN is performed directly on blood culture media using blood culture bottles identified as positive by a continuous monitoring blood culture system and which contain gram-negative bacteria as determined by gram stain. BC-GN is indicated for use in conjunction with other clinical and laboratory findings to aid in the diagnosis of bacterial bloodstream infections; however, is not used to monitor these infections. Sub-culturing of positive blood cultures is necessary to recover organisms for antimicrobial susceptibility testing (AST), for identification of organisms not detected by BC-GN, to detect mixed infections that may not be detected by BC-GN, for association of antimicrobial resistance marker genes to a specific organisms, or for epidemiological typing. The BC-GN test is performed on the Verigene System platform, which is a fully automated, bench-top, molecular diagnostics workstation consisting of Verigene Reader and a bank of up to 32 Verigene Processor SP units. The System enables the detection of bacterial DNA from blood culture, unformed stool, or nasopharyngeal swab, depending on the test, through automated nucleic acid extraction and hybridization.
