No
The description details a standard automated antimicrobial susceptibility testing system based on microdilution methodology and growth monitoring, with no mention of AI or ML techniques for data analysis or interpretation.
No.
The device is described as a laboratory aid for determining the in vitro susceptibility of Streptococcus pneumoniae to antimicrobial agents, which is a diagnostic function, not a therapeutic one.
Yes
The device is designed for antimicrobial susceptibility testing, which helps determine the effectiveness of antimicrobial agents against specific pathogens, and is intended for use "as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This information is crucial for guiding treatment decisions, making it a diagnostic tool.
No
The device description clearly outlines physical components (AST Cards, VITEK 2 System, VITEK 2 Compact) and processes involving bacterial isolates, saline, 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 Streptococcus pneumoniae" and is 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 (in this case, the susceptibility of a bacterial infection to antibiotics).
- Device Description: The description details how the device works by testing bacterial isolates in a laboratory setting using miniaturized microdilution methodology.
- Performance Studies: The performance studies compare the device's results to a "CLSI microbroth dilution reference method," which is a standard laboratory technique for in vitro testing.
- Predicate Device: The mention of a predicate device (K031865; VITEK 2 Gram Positive Moxifloxacin for Streptococcus pneumoniae) which is also an AST device, further supports its classification as an IVD.
All these points align with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes.

Intended Use / Indications for Use
VITEK® 2 Gram Positive Telithromycin for Streptococcus pneumoniae is designed for antimicrobial susceptibility testing of Streptococcus pneumoniae. VITEK 2 Gram Positive Telithromycin for Streptococcus pneumoniae is a qualitative test. It 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.
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 gramnegative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus agalactiae, and S. pneumoniae.

Device Description
VITEK® 2 Gram Positive Telithromycin for Streptococcus pneumoniae is designed for antimicrobial susceptibility testing of Streptococcus pneumoniae. It 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. 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 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.

An external evaluation was conducted with fresh and stock clinical isolates and stock challenge strains. The external evaluations were designed to confirm the acceptability of VITEK 2 Gram Positive Telithromycin for Streptococcus pneumoniae by comparing its performance with the CLSI microbroth dilution reference method.
Summary of Performance Studies
VITEK 2 Gram Positive Telithromycin for Streptococcus pneumoniae 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 Feb. 5, 2003.
The data is representative of performance on both the VITEK 2 System and VITEK 2 Compact instrument platforms, as evidenced in the AST equivalency study presented in the VITEK 2 Compact 510(k), K050002. Reproducibility and Quality Control demonstrated acceptable results.

(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.”
