The description focuses on automated microbial growth monitoring and comparison to a reference method, with no mention of AI or ML algorithms for interpretation or analysis.
No
Explanation: This device is for in vitro diagnostic use, specifically for antimicrobial susceptibility testing. It provides information to aid in determining susceptibility to antimicrobial agents, but it does not directly treat or diagnose a disease in a patient.
Yes
The device is designed for "antimicrobial susceptibility testing" and provides a "qualitative test" as a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This directly supports diagnosis by identifying effective treatments based on antimicrobial susceptibility.
No
The device description clearly states it involves physical components like "VITEK® 2 AST-GN Cards" containing antimicrobial medium and is used with the "VITEK® 2 and VITEK® 2 Compact Systems," which are instruments that fill, seal, incubate, and read the cards. This indicates a hardware component is integral to the device's function.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it is "designed for antimicrobial susceptibility testing of Gram negative bacilli" and is intended for use "as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." The term "in vitro" is a key indicator of an IVD.
- Device Description: The description details a test performed on isolated colonies (biological samples) outside of the body, using a miniaturized version of a standard laboratory technique (doubling dilution).
- Performance Studies: The performance studies compare the device's results to a "CLSI broth microdilution reference method," which is a standard laboratory method for determining antimicrobial susceptibility.
- Key Metrics: The reported metrics (Essential Agreement and Category Agreement) are standard performance measures for antimicrobial susceptibility testing devices.
- Predicate Device: The mention of a predicate device (VITEK® 2 GN Piperacillin/tazobactam) with a K number (K113200) indicates that this device is being compared to a previously cleared IVD.
All of these factors align with the definition and characteristics of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition. In this case, the information provided is the susceptibility of bacteria to an antimicrobial agent, which is crucial for guiding treatment decisions.

Device Description
The antimicrobial presented in VITEK® 2 AST-GN Cards is in concentrations equivalent by efficacy to standard method concentrations in mcg/ml. The VITEK® 2 AST Cards are essentially miniaturized versions of the doubling dilution technique for determining the minimum inhibitory concentration (MIC) microdilution methodology.
The isolate to be tested is diluted to a standardized concentration in 0.45 - 0.50% saline before being used to rehydrate the antimicrobial medium within the card. The VITEK® 2 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 MIC value along with the interpretive category result for each antimicrobial contained on the card.

Description of the training set, sample size, data source, and annotation protocol
An external evaluation was conducted with fresh and stock clinical isolates, as well as a set of challenge strains. The external evaluations were designed to confirm the acceptability of VITEK® 2 AST-GN Tobramycin by comparing its performance with the CLSI broth microdilution reference method incubated at 16-20 hrs.

Summary of Performance Studies
VITEK® 2 AST-GN Tobramycin demonstrated substantially equivalent performance when compared with the CLSI broth microdilution reference method, as defined in the FDA Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA (Issued August 28, 2009). The Premarket Notification (510[k]) presents data in support of VITEK® 2 AST-GN Tobramycin. An external evaluation was conducted with fresh and stock clinical isolates, as well as a set of challenge strains. The external evaluations were designed to confirm the acceptability of VITEK® 2 AST-GN Tobramycin by comparing its performance with the CLSI broth microdilution reference method incubated at 16-20 hrs. The data is representative of performance on both the VITEK® 2 and VITEK® 2 Compact instrument platforms.
Key Metrics

§ 866.1645 Fully automated short-term incubation cycle antimicrobial susceptibility system.
(a)
Identification. A fully automated short-term incubation cycle antimicrobial susceptibility system is a device that incorporates concentrations of antimicrobial agents into a system for the purpose of determining in vitro susceptibility of bacterial pathogens isolated from clinical specimens. Test results obtained from short-term (less than 16 hours) incubation are used to determine the antimicrobial agent of choice to treat bacterial diseases.(b)
Classification. Class II (special controls). The special control for this device is FDA's guidance document entitled “Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA.”
