Intended Use
To determine bacterial antimicrobial agent susceptibility. The MicroScan® MICroSTREP plus™ Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of aerobic streptococci, including Streptococcus pneumoniae. After inoculation, panels are incubated for 20 - 24 hours at 35°C +/- 1°C in a non-CO2 incubator, and read visually according to the Package Insert. This particular submission is for the addition of the antimicrobial Levofloxacin at concentrations of 0.12 to 16 mcg/ml to the test panel. The organisms which may be used for Levofloxacin susceptibility testing in this panel are; Streptococcus pneumoniae (including penicillin-resistant strains), Streptococcus pyogenes, Streptococcus (Group C/F), Streptococcus (Group G), Streptococcus agalactiae, Viridans group streptococci.
Device Description
The MicroScan® MICroSTREP plus™ Panel is used to determine quantitative and/or qualitative antimicrobial agent susceptibility of colonies grown on solid media of aerobic streptococci, including Streptococcus pneumoniae. After inoculation, panels are incubated for 20-24 hours at 35°C +/- 1°C in a non-CO2 incubator, and read visually according to the Package Insert. The antimicrobial susceptibility tests are miniaturizations of the broth dilution susceptibility test. Various antimicrobial agents are diluted in water, buffer or minute concentrations of broth to concentrations bridging the range of clinical interest. Panels are rehydrated with 115 ul Mueller-Hinton broth supplemented with 2-5% lysed horse blood (LHB) and buffered with 50 mM HEPES, after inoculation of the broth with a standardized suspension of the organism in saline. After incubation in a non-CO2 incubator for 20-24 hours, the minimum inhibitory concentration (MIC) for the test organism is manually read by observing the lowest antimicrobial concentration showing inhibition of growth.
More Information

Not Found

No
The device description and performance studies indicate a manual, visual reading of results based on broth dilution, with no mention of automated analysis, image processing, or AI/ML terms.

No.
This device is designed to determine the susceptibility of bacteria to antimicrobial agents, aiding in diagnostic rather than direct therapeutic purposes.

Yes

The device determines bacterial antimicrobial agent susceptibility, which is a diagnostic function used to guide treatment decisions.

No

The device description clearly outlines a physical panel that is inoculated with a bacterial suspension, incubated, and then visually read. This involves physical components and processes, not just software.

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

Here's why:

  • Intended Use: The intended use is to "determine bacterial antimicrobial agent susceptibility." This is a diagnostic test performed in vitro (outside the body) on a sample (bacterial colonies).
  • Device Description: The description details a laboratory test method involving rehydrating panels with broth, inoculating with a standardized suspension of the organism, incubating, and reading the minimum inhibitory concentration (MIC). This is a classic description of an in vitro diagnostic test for antimicrobial susceptibility.
  • Performance Studies: The performance studies compare the device's performance to a "frozen Reference panel," which is a standard practice for evaluating the accuracy of IVD tests.
  • Predicate Device: The mention of a "Predicate Device" (K963641; MicroScan® Streptococcus MIC Panel) is a strong indicator that this device is being submitted for regulatory review as an IVD, as predicate devices are used for demonstrating substantial equivalence in the IVD regulatory pathway.

All these elements point to the device being an in vitro diagnostic product used to provide information about a patient's condition (specifically, the susceptibility of bacteria isolated from a patient to certain antimicrobial agents).
