The summary describes a standard antimicrobial susceptibility testing panel and its performance compared to a reference method. There is no mention of AI or ML in the device description, intended use, or performance studies.
No.
The device is used for in-vitro diagnostic testing to determine antimicrobial susceptibility, not for treating patients.
Yes
The device is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of bacterial colonies, which is a diagnostic purpose to guide treatment decisions.
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 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) to provide information about a patient's potential response to antimicrobial treatment.
- Device Description: The description details how the device works by performing miniaturized broth dilution susceptibility tests on bacterial samples. This process 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," which is a common practice for validating the accuracy and reliability of IVD devices. The mention of "Essential Agreement" and comparison to FDA guidance for AST systems further confirms its classification as an IVD.
The device is designed to be used in vitro (outside the body) to analyze biological samples (bacterial colonies) and provide diagnostic information (antimicrobial susceptibility).

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 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 Antimicrobial Susceptibility Testing (AST) portions can be read visually, according to the Package Insert.
This particular submission is for the addition of the antimicrobial Ampicillin, at concentrations of 0.12 to 64 ug/ml for the Long Dilution Sequence and 2 - 8 µg/ml for the Breakpoint Dilution Sequence, to the test panel.
The gram-positive organisms which may be used for Ampicillin susceptibility testing in this panel are:
Enterococcus species

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® 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 (study type, sample size, AUC, MRMC, standalone performance, key results)
Efficacy total for the Rapid read method equaled two hundred and ninety three (293) isolates and Challenge total equaled seventy two (72). Results for sixteen (16) isolates, thirteen (13) in Efficacy and three (3) in Challenge, 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.
The Synergies plus™ Gram-Positive Panel demonstrated acceptable performance with an overall Essential Agreement of >97% for Ampicillin when compared with the frozen Reference panel.
Instrument reproducibility testing demonstrated acceptable reproducibility and precision for Ampicillin, with Turbidity inoculum preparation method and the WalkAway® SI System or equivalent.
Quality Control testing demonstrated acceptable results for Ampicillin.

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.”
