No
The description focuses on traditional broth dilution methods and instrument-based reading, without mentioning any AI or ML algorithms for interpretation or analysis. The performance evaluation compares instrument reads to expected results, not to an AI/ML model's output.
No.
This device is an in vitro diagnostic (IVD) device used to determine antimicrobial agent susceptibility, not to provide therapy directly.
Yes
Explanation: The device determines the susceptibility of bacteria to antimicrobial agents, which provides information crucial for diagnosing and guiding treatment for bacterial infections.
No
The device description explicitly mentions a "MicroScan® WalkAway instrument" which is a piece of hardware used for incubation and reading of the panels. The submission is for adding instrument read capability, indicating the software is part of a larger hardware system.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The primary intended use is "To determine bacterial antimicrobial agent susceptibility." This involves testing biological samples (bacterial colonies grown from patient samples) in vitro (outside the body) to provide information about a patient's health status (specifically, how susceptible a bacterial infection is to certain antibiotics).
- Device Description: The device is a panel containing various antimicrobial agents used in a laboratory setting to perform susceptibility testing on bacterial cultures. This is a classic example of an IVD.
- Performance Studies: The performance studies involve testing the device's ability to accurately determine susceptibility compared to a reference method, which is typical for IVD validation.
The device fits the definition of an In Vitro Diagnostic device as it is intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, treatment, or prevention of disease. In this case, the information is about the susceptibility of a bacterial infection to antimicrobial agents, which directly informs treatment decisions.

Intended Use / Indications for Use
Intended Use: To determine bacterial antimicrobial agent susceptibility
Indications for Use: The MicroScan MICroSTREP plus® Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of aerobic streptococci, including Streptococcus pneumoniae. After inoculation, panels are incubated for 20 – 24 hours at 35°C +/- 1°C in a non-CO2 incubator, and read visually according to the Package Insert. Additionally, the panels may be incubated in and read by a MicroScan® WalkAway instrument.
This particular submission is for the addition of instrument read capability of the antimicrobial Erythromycin, at concentrations of 0.015 to 2 mcg/ml on the MicroScan MICroSTREP plus® Panel.
The organisms which may be used for Erythromycin susceptibility testing on this panel are:
Streptococcus pneumoniae
Streptococcus pyogenes
viridans group streptococci

Device Description
The MicroScan MICroSTREP plus® Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of aerobic streptococci, including Streptococcus pneumoniae. After inoculation, panels are incubated for 20 – 24 hours at 35°C +/- 1°C in a non-CO2 incubator, and read according to the Package Insert.
The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test. 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 15 µl Mueller-Hinton broth supplemented with 2-5% lysed horse blood (LHB) and buffered with 50 mM HEPES, after inoculation of the broth with a standardized suspension of the organism in saline. After incubation in a non-CO2 incubator for 20-24 hours, the minimum inhibitory concentration (MIC) for the test organism is manually read by observing the lowest antimicrobial concentration showing inhibition of growth. Additionally, the panels may be incubated in and read by a MicroScan® WalkAway instrument.

The external evaluation was conducted with stock and CDC Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed instrument read method for the MICroSTREP plus® Panel by comparing its performance with Expected Results determined before the evaluation.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed instrument read method for the MicroScan MICroSTREP plus® Panel demonstrated substantially equivalent performance with streptococcal isolates when compared with an expected result generated on 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 MICroSTREP plus® Panel demonstrated acceptable performance with an overall Essential Agreement of 98.6% for Erythromycin instrument read results compared with the Expected Result.
Instrument reproducibility testing demonstrated acceptable reproducibility and precision with Erythromycin and the WalkAway® instrument.
Quality Control testing demonstrated acceptable results for Erythromycin.
