Intended Use
The MicroScan® Dried Gram Negative Panel is designed for use in the Confirmation of Extended-Spectrum Beta-Lactamase (ESBL) production in Escherichia coli, Klebsiella spp. and Proteus mirabilis. 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 use of cefotaxime (2, 16 µg/ml), cefotaxime/clavulanic acid (0.5/4, 4/4 µg/ml), ceftazidime (1, 8 µg/ml) and ceftazidime/clavulanic acid (0.25/4, 2/4 µg/ml) for ESBL confirmatory testing on MicroScan® Dried Gram Negative MIC/Combo Panels and the addition of automated read methods. The Gram Negative organisms which may be used for confirmation of ESBL production in this panel are: Escherichia coli Klebsiella oxytoca Klebsiella pneumoniae Proteus mirabilis
Device Description
MicroScan® Dried Gram Negative MIC/Combo Panels are designed for use in determining quantitative and/or qualitative antimicrobial agent susceptibility for Gram Negative organisms and screening for suspected ESBL production in E. coli, Klebsiella spp. and P. mirabilis. 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 at 35 °C for a minimum of 16 hours, the minimum inhibitory concentration (MIC) for the test organism is determined by observing the lowest antimicrobial concentration showing inhibition of growth.

The description focuses on traditional broth dilution methods and automated reading instruments, with no mention of AI or ML.

No
This device is for diagnosing the production of ESBL in bacteria, not for treating a condition or disease.

Yes
The device is designed for the "Confirmation of Extended-Spectrum Beta-Lactamase (ESBL) production" and for "determining quantitative and/or qualitative antimicrobial agent susceptibility for Gram Negative organisms and screening for suspected ESBL production," which are diagnostic purposes.

No

The device description explicitly mentions "MicroScan® Dried Gram Negative MIC/Combo Panels" which are physical panels containing dehydrated antimicrobial agents. The process involves rehydrating these panels and incubating them, indicating a hardware component is central to the device's function. While automated read methods are mentioned, the core device is not solely software.

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

Here's why:

  • Intended Use: The intended use explicitly states it's "designed for use in the Confirmation of Extended-Spectrum Beta-Lactamase (ESBL) production in Escherichia coli, Klebsiella spp. and Proteus mirabilis." This is a diagnostic test performed on biological samples (bacterial cultures).
  • Device Description: The description details a "miniaturizations of the broth dilution susceptibility test" which is a standard laboratory method for determining the susceptibility of microorganisms to antimicrobial agents. This is a diagnostic procedure.
  • Sample Type: The device is inoculated with a "standardized suspension of the organism," which is a biological sample.
  • Purpose: The purpose is to determine the "minimum inhibitory concentration (MIC)" and screen for "suspected ESBL production," both of which are diagnostic outcomes related to identifying and characterizing microorganisms.
  • Performance Studies: The performance studies describe testing with "stock challenge strains" and comparing results to "molecular characterization result," further indicating a diagnostic purpose.
  • Predicate Device: The predicate device listed (K020037 - MicroScan® Dried ESBL plus ESBL Confirmation Panel) is also an IVD, confirming the category of this type of product.

Therefore, based on the intended use, device description, sample type, purpose, and comparison to a known IVD predicate, the MicroScan® Dried Gram Negative Panel is an In Vitro Diagnostic device.

MicroScan® Dried Gram Negative MIC/Combo Panels are designed for use in determining quantitative and/or qualitative antimicrobial agent susceptibility for Gram Negative organisms and screening for suspected ESBL production in E. coli, Klebsiella spp. and P. mirabilis.

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 at 35 °C for a minimum of 16 hours, the minimum inhibitory concentration (MIC) for the test organism is determined by observing the lowest antimicrobial concentration showing inhibition of growth.

The antimicrobics: cefotaxime/clavulanic acid, ceftazidime and ceftazidime/clavulanic acid have been cleared for confirmation of suspected extended-spectrum beta-lactamases with E. coli, K. oxytoca and K. pneumoniae via Premarket Notification submission (K020037). Confirmation of suspected ESBL with P. mirabilis was submitted to the FDA and is pending clearance.

This Premarket Notification 510(k) presents data in support of a request for confirmatory testing of suspected extendedspectrum beta-lactamase producing E. coli, K. oxytoca, K. pneumoniae and P. mirabilis using streamlined dilutions of the antimicrobial agents recommended for confirmation testing described in the CLSI document M100-S16 for cefotaxime and ceftazidime, alone and in combination with clavulanic acid. In addition, this Premarket Notification 510(k) presents data for automated (WalkAway® and autoSCAN®-4 instruments) reads of the MicroScan® Dried Gram Negative panel with streamlined dilutions.
