No
This device is an in vitro diagnostic (IVD) tool designed to determine antimicrobial susceptibility of bacterial colonies, not to treat or prevent a disease or condition in a patient.
Yes
Explanation: The device is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of bacterial colonies, which provides information for diagnosing and treating infections.
No
The device is a physical panel containing dried 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 device is used to determine the antimicrobial susceptibility of bacterial colonies grown on solid media. This is a diagnostic test performed in vitro (outside the body) on a biological sample (bacterial colonies).
- Device Description: It describes a miniaturized broth dilution susceptibility test, which is a standard method for in vitro antimicrobial susceptibility testing.
- Performance Studies: The studies compare the device's performance to a "frozen Reference panel," which is a common practice for validating in vitro diagnostic tests. The metrics used (Essential Agreement) are also typical for evaluating the performance of AST systems.
- Predicate Device: The predicate devices listed are also MicroScan panels, which are known IVD devices for antimicrobial susceptibility testing.
The entire description points to a device designed to perform a diagnostic test on a biological sample in a laboratory setting, which is 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℃ +/- 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 vancomycin, at concentrations of 0.25 to 64 µg/ml, to the test panel.
The gram-positive organisms which may be used for vancomycin susceptibility testing in this panel are:
- Enterococcus spp. (e.g., Enterococcus faecalis)
- Staphylococcus spp.
- Staphylococcus aureus (including methicillin-resistant strains)
- Staphylococcus epidermidis (including methicillin-resistant 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 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® SJ 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 (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed MicroScan® Synergies plus™ Gram-Positive MIC/Combo Panel demonstrated substantially equivalent performance when compared with a 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 vancomycin.
The Synergies plus™ Gram-Positive Panel demonstrated acceptable performance with an overall Essential Agreement of >97% for vancomycin when compared with the frozen Reference panel.
Instrument reproducibility testing demonstrated acceptable reproducibility and precision for vancomycin, with Turbidity inoculum preparation method and the WalkAway® SI System or equivalent.
Quality Control testing demonstrated acceptable results for vancomycin.
Efficacy total for the Rapid read method equaled five hundred and seven (507) isolates. Results for forty-two (42) isolates were not reported due to read times ≥16 hours. Performance claims are based on the Rapid read method. Overnight Instrument and Manual read method(s) Essential Agreement & Categorical Agreement percentages were of equal, or greater, values than the Rapid read method.

(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.”
