No
The summary describes a traditional automated antimicrobial susceptibility testing system based on microdilution methodology and growth monitoring. There is no mention of AI or ML in the intended use, device description, or performance studies.
No.
The device is described as a laboratory aid for determining the susceptibility of microorganisms to antimicrobial agents, not for direct therapeutic treatment.
Yes
The "Intended Use / Indications for Use" explicitly states that the device is designed for "antimicrobial susceptibility testing" and is a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This indicates it helps diagnose the susceptibility of microorganisms to antibiotics, which is a diagnostic function.
No
The device description explicitly details physical components (VITEK 2 AST Cards, saline, incubator/reader) and a physical process (filling, sealing, incubation) that are integral to the device's function. It is not solely software.
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 microorganisms" and is a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
- Device Description: The description details how the device tests bacterial isolates outside the human body using a miniaturized microdilution methodology.
- Function: The device determines the susceptibility of microorganisms to antimicrobial agents, which is a diagnostic test performed on samples taken from a patient (though the sample itself isn't described as being from a specific anatomical site or age range in this text).
- Performance Studies: The performance studies compare the device's performance to a "CLSI broth microdilution reference method," which is a standard laboratory technique for in vitro testing.
- Predicate Device: The predicate device listed is also an "Antimicrobial Susceptibility Test," further indicating the device's function as an IVD.
All these points align with the definition and characteristics of an In Vitro Diagnostic device.

Intended Use / Indications for Use
VITEK® 2 Gram Negative Doripenem is designed for antimicrobial susceptibility testing of Gram negative 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 Negative is a quantitative test. Doripenem 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: Acinetobacter baumannii Escherichia coli Klebsiella pneumoniae Proteus mirabilis Pseudomonas aeruginosa
Active in vitro but clinical significance unknown: Citrobacter freundii Enterobacter cloacae Enterobacter aerogenes Klebsiella oxytoca Serrata marcescens
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
The antimicrobial presented in VITEK 2 AST Cards is in concentrations equivalent by efficacy to standard method concentrations in mog/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 - 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.

Description of the test set, sample size, data source, and annotation protocol
The external evaluations were designed to confirm the acceptability of VITEK 2 Gram Negative Doripeners by comparing its performance with the CLSI broth microdilution reference method.
Summary of Performance Studies
VITEK 2 Gram Negative Doripenem 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 March 5, 2007.
The data is representative of performance on both the VITEK 2 Compact instrument platforms, as evidenced in the AST equivalency study presented in the VITEK 2 Compact 510(k), K050002.

(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.”
