No
The document describes a traditional broth dilution susceptibility test and its performance compared to a reference method. There is no mention of AI or ML in the description, performance studies, or key metrics. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".
No.
The device is used for determining the susceptibility of microorganisms to antimicrobial agents, which aids in diagnosis and treatment selection, but it does not directly treat a disease or condition.
Yes
Explanation: The device is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of bacterial colonies, which directly aids in diagnosing the appropriate treatment for infections. It helps identify which antibiotics will be effective against specific gram-negative bacilli.
No
The device is a physical panel used for antimicrobial susceptibility testing, not a software-only device. It is incubated and read visually or with instrumentation.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The description 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-negative bacilli." This is a classic definition of an in vitro diagnostic test, as it analyzes a biological sample (bacterial colonies) outside of the body to provide information about a patient's condition (susceptibility to antibiotics).
- Device Description: The description further clarifies that the device is a "miniaturization of the broth dilution susceptibility test," which is a standard laboratory method for determining antibiotic susceptibility. This reinforces its role as a diagnostic tool performed in a lab setting.
- Performance Studies: The performance studies described involve testing the device's ability to accurately determine susceptibility compared to a "frozen Reference panel." This type of validation is typical for IVD devices to demonstrate their reliability and accuracy.
The device is designed to be used in a laboratory setting to test bacterial samples obtained from patients, providing crucial information for guiding treatment decisions. This aligns perfectly with the definition of an In Vitro Diagnostic device.

Intended Use / Indications for Use
To determine antimicrobial agent susceptibility
The MicroScan® Dried Gram-Negative 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-negative bacilli. After inoculation, panels are incubated for 16 - 20 hours at 35°C +/- 1°C 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 amoxicillin/ K. clavulanate at concentrations of 0.25/0.12 to 128/64 mcg/ml to the test panel.
The gram-negative organisms which may be used for amoxicillin/K. clavulanate susceptibility testing in this panel are:
Enterobacter species
Escherichia coli
Klebsiella species
Proteus mirabilis
