To determine antimicrobial agent susceptibility
To determine gram-positive bacterial susceptibility against the antimicrobial agent Meropenem. Organisms with indications for testing* include: Gram-Positive Bacteria Viridans group streptococci
Although viridans streptococci are indicated for testing* with the antimicrobial agent Meropenem, they are contraindicated for use with Meropenem on MicroScun Dried Gram-Positive MIC/Combo Panels.

MicroScan® Dried Gram-Positive MIC/Combo Panels
The provided text describes the 510(k) submission for the Dade MicroScan Inc. MicroScan Dried Gram-Positive MIC/Combo Panels with Meropenem. Here's a breakdown of the requested information based on the document:
1. Table of Acceptance Criteria and Reported Device Performance:
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Overall Essential Agreement with NCCLS Frozen Meropenem Reference Panel | 97.2% |
| Reproducibility and Precision | Acceptable |
| Quality Control Performance | Acceptable |
Note: The document references "FDA DRAFT document 'Review Criteria for Assessment of Antimicrobial Susceptibility Devices' (dated May 31, 1991)" as defining the acceptability. Specific numerical thresholds for "acceptable reproducibility" and "acceptable quality control performance" are not explicitly stated in this summary.
2. Sample Size Used for the Test Set and Data Provenance:
- Sample Size for Test Set: Not explicitly stated in terms of a specific number of isolates or tests. The document mentions "gram-positive external evaluations were conducted with fresh and stock Efficacy isolates and stock Challenge strains." However, the exact number is not provided.
- Data Provenance: The evaluations were "external", but the country of origin is not specified. The data is retrospective as it involves testing with "fresh and stock Efficacy isolates and stock Challenge strains" that were pre-existing.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:
- Number of Experts: Not specified.
- Qualifications of Experts: Not specified.
4. Adjudication Method for the Test Set:
- The ground truth was established by comparison with an "NCCLS frozen Meropenem Reference panel." This implies a reference standard rather than human adjudication of results from the device itself. No explicit human adjudication method (e.g., 2+1, 3+1) is mentioned.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
- No, an MRMC comparative effectiveness study was not done. The study focuses on the performance of the device against a reference method, not on human reader performance with or without AI assistance.
6. Standalone (Algorithm Only) Performance:
- Yes, the described study is effectively a standalone performance evaluation. The device (MicroScan Dried Gram-Positive MIC/Combo Panel with Meropenem) is evaluated for its ability to determine antimicrobial susceptibility independently, without human-in-the-loop interaction for the primary measurement. The overall Essential Agreement of 97.2% is a measure of its standalone performance against a reference.
7. Type of Ground Truth Used:
- The ground truth used was a reference standard: the "NCCLS frozen Meropenem Reference Panel." This is a laboratory-based, established method for determining antimicrobial susceptibility.
8. Sample Size for the Training Set:
- The document does not provide information about a separate "training set" or its sample size. The description refers to evaluation against a reference panel, indicating a validation or verification study rather than a development and training process for an AI/algorithm in the contemporary sense. This product precedes modern AI development frameworks.
9. How the Ground Truth for the Training Set Was Established:
- As no training set is described, this information is not applicable based on the provided document. The device's performance was compared to an NCCLS reference method for validation.

510(k) Summary:
The proposed MicroScan® Dried Gram-Positive MIC/Combo Panel with Meropenem demonstrated substantially equivalent performance when compared with an NCCLS frozen Meropenem Reference Panel, as defined in the FDA DRAFT document "Review Criteria for Assessment of Antimicrobial Susceptibility Devices" (dated May 31, 1991).
The Premarket Notification (510[k]) presents data in support of a new antimicrobial, Meropenen, for the MicroScan® Dried Gram-Positive MIC/Combo Panels.
The gram-positive external evaluations were conducted with fresh and stock Efficacy isolates and stock Challenge strains. The external evaluations were designed to confirm the acceptability of the proposed Dried Meropenem panels by comparing their performance with an NCCLS frozen Meropenem Reference panel.
The Dried Gram-Positive Meropenem panel demonstrated acceptable performance with an overall Essential Agreement of 97.2% when compared with the frozen Meropenem Reference panel.
Inoculum and instrument reproducibility testing was conducted; both the Gram-Positive Dried Meropenem panels demonstrated acceptable reproducibility and precision, regardless of which inoculum and WalkAway Systems) was used. method (i.e., Turbidity and Prompt), or instrument (autoScan-4
Quality Control performance was acceptable for the Gram-Positive Dried Meropenem panels.

Dear Ms. Lentsch:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). 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 (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations.
