The description focuses on a traditional broth dilution susceptibility test and does not mention any AI or ML components.
No
This device is for determining the antimicrobial susceptibility of microorganisms, which is a diagnostic function, not a therapeutic one.
Yes
The device determines the susceptibility of microorganisms to antimicrobial agents, which is a diagnostic function to guide treatment.
No
The device description clearly describes a physical panel with dried reagents that are rehydrated and incubated, indicating a hardware component is central to the device's function.
Based on the provided information, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "To determine antimicrobial agent susceptibility." This is a classic example of an in vitro diagnostic test, as it analyzes a sample (bacterial colonies) outside of the body to provide information about a patient's condition (how susceptible the bacteria are to different drugs).
- Device Description: The description details a method for performing a broth dilution susceptibility test using dehydrated panels. This process involves handling and analyzing biological samples (bacterial suspensions) in a laboratory setting, which is characteristic of IVDs.
- Performance Studies: The performance studies compare the device's performance to a "CLSI frozen Reference panel," which is a standard for evaluating the accuracy of antimicrobial susceptibility tests. This type of validation is required for IVD devices.
- Predicate Device: The mention of a "Predicate Device(s)" with a K number (K192355) and name (MicroScan Dried Gram-Negative MIC/Combo Panels Meropenem) strongly indicates that this device is being submitted for regulatory clearance as an IVD, likely through the 510(k) pathway. Predicate devices are used to demonstrate substantial equivalence for new IVDs.
The information provided clearly aligns with the definition and characteristics of an In Vitro Diagnostic device.

Device Description
MicroScan Dried Gram-Negative 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-negative bacilli.
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 evaluations were conducted with fresh and stock Efficacy and Challenge isolates. The external evaluations were designed to confirm the acceptability of the proposed additional indications for use with the Dried Gram-Negative Panel by comparing its performance with a CLSI frozen Reference panel.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed additional indications for use. Acinetobacter species, with the MicroScan Dried Gram-Negative MIC/Combo Panel with meropenem demonstrated substantially equivalent performance when compared with a CLSI 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 August 28, 2009. This Special Premarket Notification (510|k]) presents combined efficacy and challenge data in support of the addition for Acinetobacter species indications for use with MicroScan Dried Gram-Negative MC/Combo Panel with meropenem.
The Dried Gram-Negative Panel inoculated with Prompt® and read on the WalkAway instrument demonstrated acceptable performance with Acinetobacter spp. Essential Agreement (EA) of 91.1% and Categorical Agreement (CA) of 98.2% for meropenem when compared with the frozen Reference panel.
Inoculum and instrument reproducibility testing demonstrated acceptable reproducibility and precision with meropenem, regardless of which inoculum method (i.e., Turbidity or Prompt®), or instrument (autoSCAN-4 instrument or WalkAway system) was used.
Quality Control testing demonstrated acceptable results for meropenem.

Dear Elaine Duncan:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
