Intended Use
VITEK® 2 Gram Negative Levofloxacin is designed for antimicrobial susceptibility testing of Enterobacter cloacae, Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa, Serratia marcescens, Acinetobacter baumannii, Acinetobacter Iwoffi, Citrobacter koseri, Citrobacter freundii, Enterobacter aerogenes, Enterobacter sakazakii, Klebsiella oxytoca, Morganella morganii, Pantoea agglomerans, Proteus vulgaris, Providencia rettgeri, Providencia stuartii, Pseudomonas fluorescens. VITEK 2 Gram Negative Levofloxacin is a quantitative test. It is intended for use with the VITEK 2 and VITEK 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. The VITEK® 2 Antimicrobial Susceptibility Test (AST) is intended to be used with the VITEK® 2 and VITEK® 2 Compact Systems for the automated quantitative or qualitative susceptibility testing of isolated colonies for the most clinically significant aerobic gramnegative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus agalactiae, and S. pneumoniae.
Device Description
The antimicrobial presented in VITEK 2 AST Cards is in concentrations equivalent by efficacy to standard method concentrations in mog/m!. The VITEK 2 AST Cards are essentially miniaturized versions of the doubling dilution technique for determining the minimum inhibitory concentration (MIC) microdilution methodology. The bacterial isolate to be tested is diluted to a standardized concentration in 0.45% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK 2 System automatically fills, seals and places the card into the incubator/reader. The VITEK 2 Compact has a manual filling and sealing operation. The VITEK 2 monitors the growth of each well in the card over a defined period of time (up to 18 hours). At the completion of the incubation cycle, a report is generated that contains the MC value along with the interpretive category result for each antibiotic contained on the card.
More Information

No
The summary describes a standard automated antimicrobial susceptibility testing system based on microdilution methodology and growth monitoring. There is no mention of AI or ML in the device description, intended use, or performance studies. The evaluation compares the device to a standard reference method, not an AI/ML model.

No.
This device is described as a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents" and is intended for use in susceptibility testing, not for direct therapeutic treatment of patients.

Yes

The device is designed for "antimicrobial susceptibility testing" and provides "in vitro susceptibility to antimicrobial agents," which are diagnostic activities. It aids in determining the appropriate treatment by identifying how effective certain antimicrobial agents are against specific microorganisms.

No

The device description clearly outlines physical components (VITEK 2 AST Cards, VITEK 2 and VITEK 2 Compact Systems) and a physical process (diluting bacterial isolates, filling and sealing cards, incubation). While software is involved in monitoring and reporting, the core functionality relies on hardware and physical consumables.

Based on the provided text, the device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it is "designed for antimicrobial susceptibility testing" and is a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This clearly indicates testing performed outside of the body.
  • Device Description: The description details the process of testing bacterial isolates diluted in saline and placed into a card containing antimicrobial medium. This is a classic in vitro testing methodology.
  • Performance Studies: The performance studies compare the device's performance with the "CLSI broth microdilution reference method," which is a standard in vitro diagnostic technique.

The core function of the device is to test the susceptibility of bacterial isolates to antimicrobial agents in vitro (outside of a living organism), which is the definition of an IVD.

An external evaluation was conducted with fresh and stock clinical isolates and stock challenge strains. The external evaluations were designed to confirm the acceptability of VITEK 2 Gram Negative Levofloxacin by comparing its performance with the CLSI broth microdilution reference method. The data is representative of performance on both the VITEK 2 and VITEK 2 Compact instrument platforms, as evidenced in the AST equivalency study presented in the VITEK 2 Compact 510(k), K050002.
