The description focuses on a traditional microdilution methodology and automated reading of growth, with no mention of AI or ML algorithms for interpretation or analysis.
No.
The device is used for in vitro susceptibility testing to antimicrobial agents, which is a diagnostic purpose, not a therapeutic one.
Yes
The device aids in determining in-vitro susceptibility to antimicrobial agents, which is a diagnostic function to guide treatment decisions.
No
The device description clearly outlines physical components (AST Cards, VITEK 2 System) and a process involving rehydration, filling, sealing, incubation, and reading, indicating it is a hardware-based system with associated software, not a software-only device.
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 Staphylococcus aureus... It is intended for use with the VITEK 2® System 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 for diagnosis or treatment.
- Device Description: The description details how the device works by testing bacterial isolates in a laboratory setting using a miniaturized dilution technique. This is a classic method used in IVD devices for susceptibility testing.
- Intended User / Care Setting: It is described as a "laboratory aid," further reinforcing its use in a clinical laboratory setting for diagnostic purposes.
- Performance Studies: The performance studies compare the device's results to a reference method (NCCLS agar dilution), which is standard practice for validating IVD devices.
The information provided strongly aligns with the definition and characteristics of an In Vitro Diagnostic device.

Device Description
VITEK® 2 Gram Positive Moxifloxacin is designed for antimicrobial susceptibility testing of Staphylococcus aureus (methicillin-susceptible strains only). It is intended for use with the VITEK® 2 System as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. The antimicrobial presented in VITEK 2 AST 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 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 automatically fills, seals and places the card into the incubator/reader. 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 antibiotic contained on the card.

§ 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.”

Dear Ms. Weaver:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).
