The document describes a standard in vitro diagnostic device for antimicrobial susceptibility testing using broth dilution and fluorogenic identification. There is no mention of AI or ML technologies in the device description, intended use, or performance studies. The reading of results is described as being done by "MicroScan® Instrumentation" or visually, which are not indicative of AI/ML.
No
This device is an in vitro diagnostic (IVD) device used to determine antimicrobial susceptibility, not to treat a health condition.
Yes
The device is used to "determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media," which provides information on the presence and susceptibility of microorganisms, aiding in the diagnosis and treatment of infections. This falls under the definition of a diagnostic device, as it provides information for medical diagnosis.
No
The device is a physical panel with dried antimicrobial agents that is inoculated with a bacterial suspension and incubated. While it is read by instrumentation (which likely includes software), the core device being submitted is a physical panel, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is used to "determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of rapidly growing aerobic and facultative anaerobic gram-positive enterococci and staphylococci." This is a diagnostic test performed in vitro (outside of the body) on biological samples (bacterial colonies).
- Device Description: The description details how the device works by performing miniaturized broth dilution susceptibility tests on bacterial cultures. This is a standard method for in vitro diagnostic testing in microbiology.
- Anatomical Site: The "Not Applicable (in vitro diagnostic device)" entry further confirms its nature as an IVD.
- Intended User/Care Setting: While not explicitly stated, the description of the device and its use in determining antimicrobial susceptibility strongly implies use in a clinical microbiology laboratory setting, which is where IVD tests are typically performed.
The entire context of the provided information points to a device designed to perform diagnostic testing on biological samples in a laboratory setting, which is the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The MicroScan® Synergies plus™ Gram-Positive MIC/Combo Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of rapidly growing aerobic and facultative anaerobic gram-positive enterococci and staphylococci. After inoculation, panels are incubated for 4.5 - 18 hours at 35℃ +/- 1℃, in a WalkAway® SI, or equivalent, and read by the MicroScan® Instrumentation. Additionally, the panels may be incubated in a non-CO2 incubator and the Antimicrobial Susceptibility Testing (AST) portions can be read visually, according to the Package Insert.
This particular submission is for the addition of the antimicrobial gentamicin, at concentrations of 0.06 to 32 µg/ml Long Dilution Sequence for staphylococci, to the test panel.
The Gram-positive organisms which may be used for gentamicin susceptibility testing in this panel are:
Staphylococcus species (coagulase-positive and coagulase-negative).

Device Description
MicroScan® Synergies plus™ Gram-Positive MIC/Combo Panels, utilizing both the MicroScan® Rapid Fluorogenic Identification and Dried Overnight Antimicrobial Susceptibility Testing (AST) technologies, are designed for use in determining quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of rapidly growing aerobic and facultative anacrobic Gram-positive enterococci and staphylococci.
The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test that have been diluted in water and dehydrated. Various antimicrobial agents are diluted in water, buffer, or minute concentrations of broth, to concentrations bridging the range of clinical interest. Panels are rehydrated with Synergies plus" Pos Broth, after inoculation with a standardized suspension of the organism. After incubation in the WalkAway® SI, or equivalent, for 4.5 - 18 hours, the minimum inhibitory concentration (MIC) for the test organism is read by determining the lowest antimicrobial concentration showing inhibition of growth.

§ 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.”
