No
The description focuses on automated quantitative or qualitative susceptibility testing using miniaturized doubling dilution techniques and monitoring growth over time. There is no mention of AI or ML algorithms being used for interpretation or analysis.
No.
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 means it helps determine how susceptible bacteria are to certain drugs, rather than directly treating a condition in a patient.
Yes
The device is designed for antimicrobial susceptibility testing of Gram-positive microorganisms and provides quantitative or qualitative susceptibility testing results (MIC values and interpretive categories), which are used as a laboratory aid in determining in vitro susceptibility to antimicrobial agents. This directly contributes to diagnosing and guiding treatment for bacterial infections.
No
The device description clearly outlines physical components (AST Cards, VITEK 2/Compact Systems) and a process involving rehydrating media, filling/sealing cards, and incubation, indicating it is a hardware-based system with software control, 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's for "antimicrobial susceptibility testing of Gram positive microorganisms" and is a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." "In vitro" means "in glass" or "in the lab," referring to tests performed outside of a living organism.
- Device Description: The description details how the device works by testing bacterial isolates in a card containing antimicrobial medium, which is a classic in vitro method for determining susceptibility.
- Performance Studies: The performance studies compare the device's performance to a "CLSI broth microdilution reference method," which is another standard in vitro diagnostic technique.
- Predicate Device: The predicate device listed is also an IVD (VITEK 2 Gram Positive Vancomycin), indicating the regulatory pathway for this type of device.
All of these points align with the definition and characteristics of an In Vitro Diagnostic device.

Intended Use / Indications for Use
VITEK® 2 Gram Positive Daptomycin is designed for antimicrobial susceptibility testing of Gram positive microorganisms 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. VITEK 2 Gram Positive Daptomycin is a quantitative test. Daptomycin has been shown to be active against the microorganisms listed below according to the FDA label for the antimicrobial.
Active in vitro and in clinical infections:
Enterococcus faecalis (vancomycin-susceptible strains only) Staphylococcus aureus (including methicillin-resistant strains)
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 gramneqative 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 mooml. 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 - 0 .50% 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 MIC value along with the interpretive category result for each antibiotic contained on the card.

(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.”
