No
The summary describes a traditional in vitro diagnostic device (microdilution panels) for determining bacterial susceptibility. There is no mention of AI, ML, image processing, or any computational methods that would suggest the use of such technologies. The performance studies focus on agreement with a reference method and reproducibility, which are standard for this type of device.
No
This device is for determining bacterial susceptibility to an antimicrobial agent, which is a diagnostic purpose, not a therapeutic one.
Yes
Explanation: The device is used to determine bacterial susceptibility against an antimicrobial agent, which is a diagnostic function to guide treatment decisions for infections.
No
The device description explicitly states "Microdilution Minimum Inhibitory Concentration (MIC) Panels, specifically MicroScan® Dried Gram-Negative and Gram-Positive MIC/Combo Panels with Cefdinir," indicating a physical panel component, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "determine gram-negative and gram-positive bacterial susceptibility against the antimicrobial agent Cefdinir." This is a diagnostic test performed in vitro (outside of the body) on biological samples (bacterial isolates) to provide information about a patient's potential response to a specific treatment.
- Device Description: The device is described as "Microdilution Minimum Inhibitory Concentration (MIC) Panels." MIC testing is a standard laboratory method used to determine the lowest concentration of an antimicrobial agent that inhibits the visible growth of a microorganism. This is a classic example of an in vitro diagnostic test.
- Performance Studies: The performance studies describe comparing the device's performance to a "NCCLS frozen Cefdinir Reference panel," which is a common practice for validating IVD devices. The metrics reported (Essential Agreement, reproducibility, precision) are also typical for evaluating the performance of IVD tests.
The information provided clearly indicates that this device is designed to be used in a laboratory setting to perform diagnostic testing on bacterial samples, which falls squarely under the definition of an In Vitro Diagnostic device.

The gram-negative and gram-positive external evaluations were conducted with fresh and stock Efficacy isolates and stock Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed Dried Cefdinir panels by comparing their performance with an NCCLS frozen Cefdinir Reference panel.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed MicroScan® Dried Gram-Negative and Gram-Positive MIC/Combo Panel with Cefdinir demonstrated substantially equivalent performance when compared with an NCCLS frozen Cefdinir Reference Panel, as defined in the FDA DRAFT document "Review Criteria for Assessment of Antimicrobial Susceptibility Devices" (dated May 31, 1991). The Premarket Notification (510[k]) presents data in support of the new antimicrobial, Cefdinir, for the MicroScan® Dried Gram-Negative and Gram-Positive MIC/Combo Panels. Both the gram-negative and gram-positive external evaluations were conducted with fresh and stock Efficacy isolates and stock Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed Dried Cefdinir panels by comparing their performance with an NCCLS frozen Cefdinir Reference panel. The Dried gram-negative Cefdinir panel demonstrated acceptable performance with an overall Essential Agreement of 97.9% when compared with the frozen Cefdinir Reference panel. The Dried gram-positive Cefdinir panel demonstrated acceptable performance with an overall Essential Agreement of 94.0% when compared with the frozen Cefdinir Reference panel. Inoculum and instrument reproducibility testing was conducted; both the gram-negative and the gram-positive Dried Cefdinir panels demonstrated acceptable reproducibility and precision, regardless of which inoculum method (i.e., Turbidity and Prompt), or instrument (autoScan-4® and WalkAway®) was used. Quality Control performance was acceptable for both the gram-negative and the grampositive Dried Cefdinir panels.
