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.
More Information

The provided text does not explicitly list any K/DEN numbers under "Reference Device(s)". It mentions "CLSI frozen Reference panel" and "frozen Reference panel" as the comparative standard, but no K/DEN number is associated with them.

No
The description details a traditional broth dilution susceptibility test method and does not mention any AI or ML components.

No
This device is designed to determine antimicrobial agent susceptibility, which is a diagnostic function, not a therapeutic one. It helps identify effective treatments but does not administer therapy or directly treat a disease.

Yes

The device determines the minimum inhibitory concentration (MIC) for antimicrobial agents, which is a diagnostic measure for antimicrobial susceptibility.

No

The device description clearly describes a physical panel with dehydrated antimicrobial agents that is rehydrated and incubated, indicating it is a hardware-based device for antimicrobial susceptibility testing.

Yes, 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 diagnostic test performed on a sample taken from a patient (in this case, bacterial colonies grown from a sample).
  • Device Description: The description details a test performed in vitro (outside the body) using a sample (bacterial colonies) to determine a characteristic of that sample (susceptibility to antimicrobial agents).
  • Performance Studies: The performance studies compare the device's results to a reference method for determining antimicrobial susceptibility, which is a key characteristic of an IVD.

The device is designed to provide information about a patient's condition (specifically, the susceptibility of an infection-causing organism to various drugs), which is a core function of an IVD.

The external evaluations were conducted with fresh, recent and stock Efficacy isolates and stock Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed Dried Gram-Negative Panel by comparing its performance with a CLSI frozen Reference panel.

Summary of Performance Studies

The proposed MicroScan Dried Gram-Negative MIC/Combo Panel 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. The Premarket Notification (510[k]) presents data in support of the MicroScan Dried Gram-Negative MIC/Combo Panel with ceftazidime.

The Dried Gram-Negative Panel inculated with Prompt® and read on the WalkAway instrument demonstrated acceptable performance with an Enterobacterales Essential Agreement (EA) of 92.1% and Categorical Agreement (CA) of 95.2%, Pseudomonas aeruginosa EA of 91.3% and CA of 96.2%, and Acinetobacter spp. EA of 93.1% and CA of 94.3% for ceftazidime when compared with the frozen Reference panel.

Inoculum and instrument reproducibility testing demonstrated acceptable reproducibility and precision with ceftazidime, 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 ceftazidime.

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.
