The description focuses on a miniaturized version of the doubling dilution technique and automated monitoring of growth, with no mention of AI or ML algorithms for interpretation or analysis.
No
This device is an in vitro diagnostic device used as a laboratory aid for antimicrobial susceptibility testing, determining a microorganism's susceptibility to antimicrobial agents, rather than directly treating a patient.
Yes
The device is described as a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents" and is used for "antimicrobial susceptibility testing," which are diagnostic procedures to determine the effectiveness of antibiotics against specific microorganisms.
No
The device description clearly outlines physical components (VITEK® 2 AST-GN Cards, saline, incubator/reader) and a physical process (filling, sealing, incubation, monitoring growth). While software is involved in generating the report and potentially controlling the process, the core of the device is a physical in vitro diagnostic test system.
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 how the device tests isolated colonies in a laboratory setting using a miniaturized version of a standard laboratory method (doubling dilution technique).
- Performance Studies: The performance studies compare the device's results to a "CLSI broth microdilution reference method," which is a standard laboratory technique for in vitro testing.
- Intended User/Care Setting: The intended user is a "laboratory aid," further confirming its use in a laboratory environment for diagnostic purposes.
All these points align with the definition and characteristics of an In Vitro Diagnostic device.

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.

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 Cefepime by comparing its performance with the CLSI broth microdilution reference method incubated at 16-20 hrs.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
VITEK® 2 AST-GN Cefepime 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 data is representative of performance on both the VITEK®2 and VITEK® 2 Compact instrument platforms. VITEK® 2 AST-GN Cefepime demonstrated acceptable performance of 93.8% overall Essential Agreement and 96.1% overall Category Agreement with the reference method.

(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.”
