MicroScan® MICroSTREP plus® Panel
Not Found
No
The summary describes a traditional broth dilution susceptibility test read visually or by an instrument, with no mention of AI or ML in the device description, performance studies, or key metrics.
No.
This device is an in vitro diagnostic (IVD) device used to determine bacterial antimicrobial agent susceptibility, which provides information for patient treatment but does not directly treat or diagnose a condition.
Yes
The device is used to determine bacterial antimicrobial agent susceptibility, which involves identifying the effectiveness of antimicrobial agents against specific bacteria, a process crucial for diagnosing and guiding treatment for bacterial infections.
No
The device description explicitly mentions a "MicroScan® WalkAway instrument" which is a piece of hardware used to incubate and read the panels. The submission is for the addition of instrument read capability, indicating the software is part of a larger hardware system.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The primary intended use is "To determine bacterial antimicrobial agent susceptibility." This involves testing biological samples (bacterial colonies grown from patient samples) in vitro (outside the body) to provide information about a patient's health status (specifically, how susceptible their infection is to certain antibiotics).
- Device Description: The device is a panel containing various antimicrobial agents used in a laboratory setting to perform susceptibility testing on bacterial isolates. This is a classic description of an IVD.
- Performance Studies: The performance studies described involve testing the device's ability to accurately determine susceptibility compared to a reference method, which is a standard practice for evaluating IVDs.
- Regulatory Context: The mention of the "FDA document 'Class II Special Controls Guidance Document: Antimicrobial Susceptibility Test (AST) Systems; Guidance for Industry and FDA'" strongly indicates that this device falls under the regulatory framework for IVDs in the United States. AST systems are explicitly classified as IVDs.
Therefore, based on the provided information, the MicroScan MICroSTREP plus® Panel is an In Vitro Diagnostic device.

Intended Use / Indications for Use
To determine bacterial susceptibility to Chloramphenicol.
For determining antimicrobic susceptibility with aerobic streptococci including Streptococcus pneumoniae.
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. Additionally, the panels may be incubated in and read by a MicroScan ® WalkAway instrument.
This particular submission is for the addition of instrument read capability of the antimicrobial Chloramphenicol, at concentrations of 1 to 32 mcg/ml on the MicroScan MICroSTREP plus ® Panel.
The organisms which may be used for Chloramphenicol susceptibility testing on this panel are: Susceptible streptococci, including Streptococcus pneumoniae

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 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. Additionally, the panels may be incubated in and read by a MicroScan® WalkAway instrument.

The external evaluation was conducted with stock and CDC Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed instrument read method for the MICroSTREP plus® Panel by comparing its performance with Expected Results determined before the evaluation.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The proposed instrument read method for the MicroScan MICroSTREP plus® Panel demonstrated substantially equivalent performance with streptococcal isolates when compared with an expected result generated on 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 February 5, 2003. The MICroSTREP plus® Panel demonstrated acceptable performance with an overall Essential Agreement of 100% for Chloramphenicol instrument read results compared with the Expected Result. Instrument reproducibility testing demonstrated acceptable reproducibility and precision with Chloramphenicol and the WalkAway® instrument. Quality Control testing demonstrated acceptable results for Chloramphenicol.

Dear Ms. Mende:
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. 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 such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. 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.
