The device description explicitly states that the panels are "read visually according to the Package Insert" and the MIC is "manually read by observing the lowest antimicrobial concentration showing inhibition of growth." There is no mention of automated analysis, image processing, or any terms related to AI/ML.
No
This device determines bacterial susceptibility to antimicrobials, which guides treatment but does not directly treat a condition.
Yes
The device determines bacterial susceptibility to antimicrobial agents, which is a diagnostic function used to guide treatment.
No
The device description clearly outlines a physical panel (MicroScan® MICroSTREP plus™ Panel) that is inoculated, incubated, and visually read. This involves physical components and processes, not just software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "determine bacterial susceptibility to Tetracycline" and "For determining antimicrobic susceptibility with aerobic streptococci, including Streptococcus pneumoniae." This clearly indicates the device is used to perform tests on biological samples (bacterial cultures) in vitro (outside the body) to provide information about a patient's condition (specifically, how susceptible their bacterial infection is to a particular antibiotic).
- Device Description: The description details a laboratory test method (broth dilution susceptibility test) performed on bacterial cultures. It involves incubating the organism with different concentrations of an antimicrobial agent and observing the results. This is a classic example of an in vitro diagnostic procedure.
- Performance Studies: The performance studies compare the device's results to a "Reference panel," which is typical for validating an IVD. The metrics like "Essential Agreement" are also relevant to IVD performance evaluation.
The device is designed to be used in a laboratory setting to analyze biological samples and provide diagnostic information, which aligns perfectly with the definition of an In Vitro Diagnostic device.

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 visually 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 115 ul 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.

Summary of Performance Studies
The proposed MicroScan® MICroSTREP plus™ Panel demonstrated substantially equivalent performance with streptococcal isolates when compared with an NCCLS frozen Reference Panel, as defined in the FDA DRAFT document "Guidance on Review Criteria for Assessment of Antimicrobial Susceptibility Devices", dated March 8, 2000.
The Premarket Notification (510[k]) presents data in support of the new MICroSTREP plus™ Panel with Tetracycline.
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 MICroSTREP plus™ Panel by comparing its performance with an NCCLS frozen Reference panel. The MICroSTREP plus™ Panel demonstrated acceptable performance with an overall Essential Agreement of 92.9% for Tetracycline when compared with the frozen Reference panel.
Reproducibility testing demonstrated acceptable reproducibility and precision with Tetracycline.
Quality Control testing demonstrated acceptable results for Tetracycline.
