Intended Use
The VITEK® Gram Positive Susceptibility Test is intended to be used with the VITEK® System for automated quantitative or qualitative susceptibility testing of isolated colonies of the most clinically significant aerobic gram-negative bacilli, Staphylococcus spp., Enterococcus spp., Streptococcus agalactiae, and S. pneumoniae. VITEK® Gram Positive Rifampin is designed for antimicrobial susceptibility testing of Staphylococcus aureus and Staphylococcus epidermidis. VITEK Gram Positive Rifampin is intended for use with the VITEK System as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents.
Device Description
VITEK® Gram Positive Rifampin is designed for antimicrobial susceptibility testing of Staphyloccocus aureus and Staphylococcus epidermidis. It is intended for use with the VITEK® System as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents. The antimicrobial presented in VITEK GPS Cards is in concentrations equivalent by efficacy to standard method concentrations in mcg/ml. The VITEK GPS Cards are essentially miniaturized versions of the doubling dilution technique for determining the minimum inhibitory concentration (MIC) microdilution methodology. After the card is inoculated with a standardized organism suspension, it is placed in the Reader/Incubator of the VITEK System. Organism growth inside the card is optically monitored throughout the 6-15 hour incubation cycle. MIC results are automatically calculated once a predetermined growth threshold is reached, and a report is generated that contains the MIC result and the interpretive category result.

No
The description focuses on optical monitoring and automated calculation based on a predetermined growth threshold, not AI/ML algorithms. There is no mention of AI, ML, or related terms.

No
The device is a laboratory aid for determining in vitro antimicrobial susceptibility, not a device used to treat patients or alleviate a medical condition.

Yes

The device is intended for susceptibility testing to determine the in vitro susceptibility of microorganisms to antimicrobial agents, which is a key component of diagnosing and guiding treatment for infections. It's explicitly described as a "laboratory aid in the determination of in vitro susceptibility to antimicrobial agents," implying its role in the diagnostic process.

No

The device description explicitly mentions "VITEK GPS Cards" which are physical components containing antimicrobial agents and are inoculated with organism suspensions. The system also includes a "Reader/Incubator" which is hardware. Therefore, the device is not software-only.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states it's for "in vitro susceptibility testing of isolated colonies" and "as a laboratory aid in the determination of in vitro susceptibility to antimicrobial agents." This clearly indicates testing is performed outside of the body on biological samples (isolated colonies of bacteria).
  • Device Description: The description details how the device works by "optically monitored throughout the 6-15 hour incubation cycle" after being "inoculated with a standardized organism suspension." This process of testing a biological sample in a laboratory setting is characteristic of an IVD.
  • Performance Studies: The performance studies compare the device's performance to a "reference method" for susceptibility testing, further confirming its role in laboratory diagnostics.

The definition of an In Vitro Diagnostic (IVD) is a medical device that is used to perform tests on samples such as blood, urine, or tissue, to detect diseases or other conditions. This device fits that description by testing bacterial isolates to determine their susceptibility to antibiotics.

§ 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.”
