The description focuses on traditional broth dilution susceptibility testing and automated reading of growth inhibition, with no mention of AI/ML for interpretation or analysis.
No
This device is an in-vitro diagnostic (IVD) device used for antimicrobial susceptibility testing, not a therapeutic device. It helps determine the susceptibility of bacteria to antimicrobial agents, which guides treatment but does not directly provide therapy.
Yes
The device is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of bacterial colonies, which directly aids in diagnosing the appropriate treatment for infections.
No
The device is a physical panel containing dehydrated antimicrobial agents used for susceptibility testing, requiring incubation and reading by instrumentation or visually. It is not solely 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 staphylococci and enterococci." This is a diagnostic test performed on biological samples (bacterial colonies) outside of the body (in vitro).
- Device Description: The description details how the device works by performing miniaturized broth dilution susceptibility tests on bacterial samples. This is a standard method for in vitro diagnostic testing in microbiology.
- Performance Studies: The performance studies compare the device's performance to a "frozen Reference panel" and a "CLSI frozen Reference Panel," which are typical comparisons for validating the accuracy of an IVD device.
- Predicate Device: The mention of "Predicate Device(s)" with K numbers (which are associated with FDA premarket notifications for medical devices, including IVDs) further confirms its classification as a medical device, and given its function, specifically an IVD.
The device is designed to provide information about the susceptibility of bacteria to antimicrobial agents, which is crucial for diagnosing and guiding treatment of infections. This clearly falls under the definition of 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 staphylococci and enterococci. 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 AST portions can be read visually, according to the Package Insert. This particular submission is for the addition of the antimicrobial agent Trimethoprim/Sulfamethoxazole, at concentrations of 0.5/9.5 to 8/152 ug/ml, to the test panel. The gram-positive organisms which may be used for Trimethoprim/Sulfamethoxazole susceptibility testing in this panel are: Staphylococcus aureus Staphylococcus epidermidis Staphylococcus species - Coagulase Negative Staphylococcus saprophyticus

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 antimicrobial agent susceptibility of colonies grown on solid media of rapidly growing aerobic and facultative anaerobic gram-positive staphylococci and enterococci. 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 System, 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.

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 Synergies plus" Gram-Positive Panel by comparing its performance with a frozen Reference panel. Challenge strains were compared to Expected Results determined prior to the evaluation.
Summary of Performance Studies
The proposed MicroScan® Synergies plus™ Gram-Positive MIC/Combo Panel demonstrated substantially equivalent performance when compared with a CLSI frozen Reference Panel, as defined in the FDA document "Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA', dated February 5, 2003. The Premarket Notification (510/k]) presents data in support of the MicroScan® Synergies plus™ Gram-Positive MIC/Combo Panel with Trimethoprim/Sulfamethoxazole. The Synergies plus" Gram-Positive Panel demonstrated acceptable performance with an overall Essential Agreement of >98% for Trimethoprim/Sulfamethoxazole when compared with the frozen Reference panel. Instrument reproducibility testing demonstrated acceptable reproducibility and precision for Trimethoprim/Sulfamethoxazole, with Turbidity inoculum preparation method and the WalkAway® System or equivalent. Quality Control testing demonstrated acceptable results for Trimethoprim/Sulfamethoxazole.

(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.”
