MicroScan® Synergies plus™ 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 (Enterobacteriaceae, glucose non-fermenters, and non-Enterobacteriaceae glucose fermenters. After inoculation, panels are read on the WalkAway® SI System or equivalent (upgraded WalkAway® 40 or WalkAway® 96) according to the Package Insert. This particular submission is for the antimicrobial Ceftriaxone on the Synergies plus™ "Gram-Negative MIC/Combo Panels. The Gram-Negative organisms which may be used for Ceftriaxone susceptibility testing in this panel are: Acinetobacter calcoaceticus Escherichia coli Enterobacter spp. (except Enterobacter cloacae) Klebsiella pneumoniae Klebsiella oxytoca Morganella morganii Proteus mirabilis Providencia spp. Pseudomonas aeruginosa Serratia marcescens Shigella spp. Salmonella spp. The MicroScan® Synergies plus™ Gram-Negative with Ceftriaxone is not intended for use with: Citrobacter son Enterobacter cloacae Proteus vulgaris
Device Description
MicroScan® rapID/S plus™ 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 MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panels are read on the WalkAway® System or equivalent (upgraded WalkAway® 40 or WalkAway® 96 instruments). The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test that have been diluted in Mueller-Hinton Broth to concentrations bridging the range of clinical interest and are presented in micro-titer wells in dried form. rapID/S plus™ panels are inoculated with a standardized suspension of the organism and incubated at 35℃ in the WalkAway® SY System or equivalent for 4.5 - 18 hours. The minimum inhibitory concentration (MIC) for the test organism is determined by the lowest antimicrobial concentration showing inhibition of growth.

No
The summary describes a traditional broth dilution susceptibility test read by an automated system, with no mention of AI, ML, or image processing for interpretation.

No.
The device is used to determine the susceptibility of bacteria to antimicrobial agents, which is a diagnostic function, not a therapeutic one.

Yes

This device, the MicroScan® Synergies plus™ Gram-Negative MIC/Combo Panel, is used to determine the antimicrobial susceptibility of bacteria, which is a diagnostic purpose to guide treatment decisions.

No

The device description explicitly states it is a "MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panels" which are physical panels containing dried antimicrobial agents. It also mentions being read on the "WalkAway® System or equivalent," which are hardware instruments. This is not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use explicitly states that 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 example 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 details how the device works by performing "miniaturizations of the broth dilution susceptibility test" using "micro-titer wells in dried form". This process involves testing the interaction of the organism with antimicrobial agents in a laboratory setting, which is the core of in vitro diagnostics.
  • Performance Studies: The performance studies compare the device's results to a "NCCLS frozen Reference panel", which is a standard method for evaluating the accuracy of antimicrobial susceptibility testing devices. This type of validation is typical for IVDs.

The device is designed to be used in a laboratory setting to analyze a biological sample (bacterial colonies) to provide information about the susceptibility of those bacteria to specific antimicrobial agents. This directly aligns with the definition of an In Vitro Diagnostic device.

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 rapID/S plus™ Gram-Negative Panel by comparing its performance with an NCCLS frozen Reference panel. Challenge strains were compared to Frozen Results determined prior to the evaluation.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The proposed MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panel demonstrated substantially equivalent performance when compared with an NCCLS frozen Reference Panel, as defined in the FDA DRAFT document "Guidance on Review Criteria for Assessment of Antimicrobial Susceptibility Devices", dated March 8, 2000. The Premarket Notification (510[k]) presents data in support of the MicroScan® rapID/S plus™ Gram-Negative MIC/Combo Panel with Ceftriaxone.

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 rapID/S plus™ Gram-Negative Panel by comparing its performance with an NCCLS frozen Reference panel. Challenge strains were compared to Frozen Results determined prior to the evaluation. The rapID/S plus™ Gram-Negative Panel demonstrated acceptable performance with an overall Essential Agreement of 95.9% for Ceftriaxone long dilutions and 89.6% Categorical Agreement for breakpoint dilutions when compared with the frozen Reference panel.

Identification. A fully automated short-term incubation cycle antimicrobial susceptibility system is a device that incorporates concentrations of antimicrobial agents into a system for the purpose of determining in vitro susceptibility of bacterial pathogens isolated from clinical specimens. Test results obtained from short-term (less than 16 hours) incubation are used to determine the antimicrobial agent of choice to treat bacterial diseases.(b)
Classification. Class II (special controls). The special control for this device is FDA's guidance document entitled “Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA.”

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 (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (sections 531-542 of the Act); 21 CFR 1000-1050.

This letter will allow you to continue marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
