The summary describes a traditional broth dilution susceptibility test system and its performance metrics (Essential Agreement). There is no mention of AI, ML, or any computational methods that would suggest their use in determining susceptibility. The reading is described as determining the lowest concentration showing inhibition of growth, which is a standard method for MIC determination.
No.
This device is an in vitro diagnostic (IVD) device used for antimicrobial susceptibility testing, which helps determine the effectiveness of antimicrobial agents against specific microorganisms. It does not directly treat or diagnose a disease.
Yes
The device is used to determine the susceptibility of bacterial colonies to antimicrobial agents, which provides information for diagnosing and treating infections.
No
The device description clearly outlines a physical panel with dehydrated antimicrobial agents that are rehydrated and incubated. While instrumentation is used to read the results, the core of the device is a physical panel, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly 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 the body) on biological samples (bacterial colonies).
- Device Description: The description further clarifies that the device performs "Antimicrobial Susceptibility Testing (AST)," which is a common type of in vitro diagnostic test used to determine how effective different antibiotics are against a specific bacterial infection.
- Performance Studies: The performance studies describe comparing the device's performance to a "frozen Reference panel," which is typical for validating the accuracy of an IVD device. The metric used, "Essential Agreement," is also a standard measure for evaluating the performance of AST devices.
- Predicate Device: The mention of a "Predicate Device" (MicroScan® Dried Gram-Positive Panels) is a strong indicator that this is a medical device undergoing regulatory review, and the predicate device is also an IVD.
Therefore, based on the provided information, the MicroScan® Synergies plus™ Gram-Positive MIC/Combo Panel is an In Vitro Diagnostic device.

Intended Use / Indications for Use
To determine antimicrobial agent susceptibility.
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°C +/- 1°C, 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 clindamycin, at concentrations of 0.03 to 8 ug/ml Long Dilution Sequence and 0.12 - 2 ug/ml 5-Dilution Breakpoint Sequence, for Staphylococcus spp., to the test panel.
The Gram-positive organisms which may be used for clindamycin susceptibility testing in this panel are:
- Staphylococcus aureus (penicillinase and non-penicillinase producing strains)
- . Staphylococcus epidermidis (penicllinase and non-penicillinase producing strains)

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 anaerobic 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.

(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.”
