FDA Devices recall · Reported August 20, 2014
Verigene Gram-Negative Blood Culture Nucleic Acid Test (BC-GN), performed using the sample-to-result Verigene System, is a qualitative multiplexed in vitro diagnostic test for the simultaneous detection and identification of selected gram-negative bacteria and resistance markers. 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.

Recall Insight
This recall's affected scope, documented in the Recall Profile below, stays within a single-region or limited-distribution footprint. Distribution scope (see Distribution below) directly affects the consumer exposure window and determines whether a recall remains regional or escalates into a nationwide advisory.
Within the same product category the archive holds 6 closely related recalls, 6 from FDA Devices - clustering in a narrow category often points to a systemic quality-control or supplier issue rather than a one-off defect. Always verify the recall number against the official agency record before acting.

Product description
Verigene Gram-Negative Blood Culture Nucleic Acid Test (BC-GN), performed using the sample-to-result Verigene System, is a qualitative multiplexed in vitro diagnostic test for the simultaneous detection and identification of selected gram-negative bacteria and resistance markers. 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.
Reason for recall
Nanosphere has determined that a portion of BC-GN Test Cartridge Lot number 040214021A has an elevated risk for No Call results and False Negative results. The BC-GN Test Cartridge (20-006-021) is distributed as part of the Verigene BC-GN Test Kit (20-005-021), which is labeled as "IVD". Therefore, Nanosphere has initiated a voluntary recall to retrieve the following BC-GN Test Cartridges: Test Ca
