The description focuses on traditional broth dilution susceptibility testing and visual or instrument-assisted reading of growth inhibition. There is no mention of AI or ML in the intended use, device description, or performance studies. The "instrumentation" mentioned likely refers to automated readers that interpret the results based on pre-defined thresholds, not AI/ML algorithms.
No.
This device is designed to determine the susceptibility of bacteria to antimicrobial agents, which is a diagnostic function, not a therapeutic one. It helps guide treatment but does not directly treat a condition.
Yes
The device is used to determine the susceptibility of microorganisms to antimicrobial agents, which is a diagnostic function to guide treatment.
No
The device is a physical panel containing dehydrated antimicrobial agents used for laboratory testing, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states 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 cocci." This is a classic description of an in vitro diagnostic test, as it's performed on biological samples (bacterial colonies) outside of the body to provide information about a patient's condition (susceptibility to antibiotics).
- Device Description: The "Device Description" further clarifies that the device performs "antimicrobial susceptibility tests" which are "miniaturizations of the broth dilution susceptibility test." This confirms it's a laboratory test designed to diagnose or provide information about a disease or condition.
- Performance Studies: The "Summary of Performance Studies" describes comparisons to a "NCCLS frozen Reference panel," which is a standard for evaluating the performance of diagnostic tests. The metrics used, such as "Essential Agreement," are also common in the evaluation of IVDs.
The device is designed to be used in a laboratory setting to test bacterial samples and provide information that can guide clinical decisions regarding antibiotic treatment. This aligns perfectly with the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
The MicroScan® Dried 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 cocci. Panels are incubated for 16 – 20 hours at 35℃ +/- 1℃ in a non-CO2 incubator, and read either visually or with MicroScan instrumentation, according to the Package Insert.
This particular submission is for the addition of the antimicrobial Erythromycin at concentrations of 0.25 to 16 mcg/ml to the test panel.
The gram-positive organisms which may be used for Erythromycin susceptibility testing in this panel are:
Staphylococcus aureus

Device Description
MicroScan® Dried Gram-Positive MIC/Combo Panels 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 cocci.
The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test that have been diluted in broth and dehydrated. Various antimicrobial agents are diluted in broth to concentrations bridging the range of clinical interest. Panels are rehydrated with water after inoculation with a standardized suspension of the organism. After incubation in a non-CO2 incubator for 16-20 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 Dried Gram-Positive Panel by comparing its performance with an NCCLS frozen Reference panel. Challenge strains were compared to Expected Results determined prior to the evaluation.
Summary of Performance Studies
The proposed MicroScan® Dried Gram-Positive MIC/Combo Panel demonstrated substantially equivalent performance when compared with an NCCLS 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® Dried Gram-Positive MIC/Combo Panel with Erythromycin.
The Dried Gram-Positive Panel demonstrated acceptable performance with an overall Essential Agreement of >96% for Erythromycin when compared with the frozen Reference panel.
Inoculum and instrument reproducibility testing demonstrated acceptable reproducibility and precision with Erythromycin, regardless of which inoculum method (i.e., Turbidity and Prompt), or instrument (autoSCAN-4® and WalkAway®) was used.
Quality Control testing demonstrated acceptable results for Erythromycin.
