The summary describes an automated system for antimicrobial susceptibility testing based on miniaturized doubling dilution, monitoring growth over time. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in the provided text. The performance evaluation compares the device to a reference method, not a training/test set for an AI model.
No
The device is a laboratory aid for antimicrobial susceptibility testing, providing quantitative or qualitative susceptibility results, not a direct therapeutic treatment device.
Yes
The device aids in the determination of in vitro susceptibility to antimicrobial agents, providing diagnostic information about the effectiveness of antibiotics against specific microorganisms.
No
The device description clearly outlines physical components like "VITEK® 2 AST Cards," a "VITEK® 2" system, and a "VITEK® 2 Compact" system, which are hardware. The software is used to process data from these hardware components.
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 with the VITEK® 2 and VITEK® 2 Compact Systems as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This clearly indicates it is used to test samples in vitro (outside the body) to provide information about a patient's condition (susceptibility to antibiotics).
- Device Description: The description details how the device works by testing isolated colonies in a miniaturized microdilution methodology. This is a standard method for in vitro diagnostic testing in microbiology.
- Performance Studies: The performance studies compare the device's results to a "CLSI broth microdilution reference method," which is a recognized standard for in vitro susceptibility testing.
- Predicate Device: The mention of a predicate device (K172731; VITEK® 2 AST-GN Amikacin) further confirms its classification as a medical device, and specifically an IVD, as predicate devices are used for comparison in regulatory submissions for new medical devices, including IVDs.
- Intended User: The intended user is a "laboratory aid," which aligns with the use of IVDs in clinical laboratories.
All these factors strongly indicate that the VITEK® 2 AST-Gram Negative Delafloxacin is 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.
