No
The device description explicitly states that the minimum inhibitory concentration (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.
The device is used to determine the susceptibility of bacteria to antimicrobial agents, which aids in diagnosis and treatment planning rather than directly treating a condition.
Yes
The device determines antimicrobial agent susceptibility of bacterial colonies, which is a diagnostic function used to guide treatment decisions for bacterial infections.
No
The device description clearly outlines a physical panel with wells containing antimicrobial agents, requiring incubation and manual visual reading. This involves physical components and processes, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "determine bacterial antimicrobial agent susceptibility" of specific organisms (aerobic streptococci, including Streptococcus pneumoniae). This is a diagnostic test performed in vitro (outside the body) on a biological sample (bacterial colonies grown on solid media).
- Device Description: The description details a miniaturized broth dilution susceptibility test where antimicrobial agents are diluted and incubated with a standardized suspension of the organism. The results (minimum inhibitory concentration) are read manually. This process is characteristic of an in vitro diagnostic test used to assess the properties of a biological sample.
- Performance Studies: The performance studies compare the device's performance to a reference panel, which is standard practice for evaluating the accuracy and reliability of an IVD. The metric used, "Essential Agreement," is also a common measure in the evaluation of antimicrobial susceptibility testing devices.
The device is designed to provide information about the susceptibility of bacteria to antimicrobial agents, which is crucial for guiding treatment decisions. This falls squarely within the definition of an In Vitro Diagnostic device.

After inculation, 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 (MC) 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 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 MCroSTREP plus™ Panel demonstrated acceptable performance with an overall Essential Agreement of 99% for Amoxicillin/Clavulanic Acid when compared with the frozen Reference panel.
Reproducibility testing demonstrated acceptable reproducibility and precision with Amoxicillin/ Clavulanic Acid.
Quality Control testing demonstrated acceptable results for Amoxicillin/Clavulanic Acid.
