No
The summary describes a standard broth dilution susceptibility test read by an automated system, with no mention of AI or ML in the device description, intended use, or performance studies.
No
This device is for determining the antimicrobial susceptibility of bacteria, which is a diagnostic purpose, not a therapeutic one.
Yes
This device is used to determine the antimicrobial susceptibility of organisms, which aids in diagnosing the appropriate treatment for infections.
No
The device description clearly states that the panels are read on the WalkAway® SI System or equivalent instruments, which are hardware components. The panels themselves are also physical, dried media. The submission is for a specific antimicrobial agent on these physical panels, read by a hardware system.
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-Negative bacilli." This is a diagnostic test performed in vitro (outside the living body) on biological samples (bacterial colonies).
- Device Description: The description details how the device works by using miniaturized broth dilution susceptibility tests to determine the minimum inhibitory concentration (MIC) of antimicrobial agents. This process is a standard method for in vitro diagnostic testing of bacterial susceptibility.
- Performance Studies: The performance studies compare the device's performance to a "NCCLS frozen Reference panel," which is a common practice for validating in vitro diagnostic tests. The metrics reported (Essential Agreement) are also typical for evaluating the performance of antimicrobial susceptibility testing devices.
- Predicate Device: The predicate device listed is "MicroScan Dried Gram Negative MIC/Combo Panels," which are also IVDs used for similar purposes.
The device is designed to provide information about the susceptibility of bacteria to antimicrobial agents, which is crucial for guiding treatment decisions in a clinical setting. This falls squarely within the definition of an In Vitro Diagnostic device.

Device Description
MicroScan® Synergies plus™ Gram-Negative MIC/Combo Panels 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 anaerobic gram-negative bacilli. The MicroScan® Synergies plus™ Gram-Negative MIC/Combo Panels are read on the WalkAway® SI System or equivalent (upgraded WalkAway® 40 or WalkAway® 96 instruments).
The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test that have been diluted in Mueller-Hinton Broth to concentrations bridging the range of clinical interest and are presented in micro-titer wells in dried form. rapID/S plus™ panels are inoculated and rehydrated with a standardized suspension of the organism and incubated at 35℃ in the WalkAway® SY System or equivalent for 4.5 - 18 hours. The minimum inhibitory concentration (MIC) for the test organism is determined by the lowest antimicrobial concentration showing inhibition of growth.

The external evaluation was conducted with fresh and stock Efficacy isolates and stock Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed rapID/S plasm-Negative Panel by comparing its performance with an NCCLS frozen Reference panel. Challenge strains were compared to Expected Results determined prior to the evaluation.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panel demonstrated substantially equivalent performance when compared with an NCCLS frozen Reference Panel, as defined in the FDA DRAFT document "Guidance on Review Criteria for Assessment of Antimicrobial Susceptibility Devices", dated March 8, 2000.

(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.”
