HardyDisk™ Antimicrobial Seasitivity Disks are used for semi-quantitative in vitro susceptibility testing by the agar diffusion test proccdure (Kirby-Bauer) of rapidly growing and certain fastidious bacterial vathogens. Standardized methods for agar diffusion testing have been described for Euterobacteriaccas, Staphylococcus spp., Pseudomonas spn., Acinetobacter spp., Listerta monocytogenes, Enterococcus spp., other streptococci and, hy modified procedures, Haemophilus influenzae, Neisseria gonorrhoeae and Streptococcus pneumoniae.
Hardy Disk™ Erythromycin is indicated for in vitro activity against Staphylococcus spp., and Streptococcus spp. including S. pneumoniae.
HardyDisk™ Erythromycin 15mcg is an antimicrobial sensitivity disk.
The provided text is a 510(k) premarket notification letter from the FDA to Hardy Diagnostics for their HardyDisk™ Erythromycin 15mcg. While it confirms the device's substantial equivalence to a predicate device and its regulatory classification, it does not contain the detailed study information or acceptance criteria requested.
Therefore, I cannot provide a response filling out the requested table and study details. The document is primarily a regulatory approval letter and an "Indications for Use Statement."

The CEDIA Cardiac TDM Multi-Cals are used to calibrate the CEDIA assays for digoxin, N-acetylprocainamide, and procainamide, in human serum and plasma.
The CEDIA Cardiac TDM Calibrators are manufactured using bovine serum albumin, digoxin, N-acetylprocainamide, procainamide, stabilizers, and preservatives. The drugs are appropriately spiked into the calibrator matrix to the correct calibrator concentration levels. The calibrators are in process checked and quality controlled against in-house reference calibrators (prepared using a similar procedure) which have been value assigned by comparison to the predicate device to ensure correct assay calibration.
The provided text is a 510(k) Summary for the CEDIA Cardiac TDM Multi-Cals, which are calibrators for therapeutic drug monitoring assays. This document focuses on demonstrating substantial equivalence to predicate devices, not on the performance of a diagnostic device that detects or measures a condition. Therefore, many of the requested elements for describing acceptance criteria and a study proving device performance (like sensitivity, specificity, or human reader improvement with AI) are not applicable to this type of submission.
However, I can extract the relevant information regarding the "performance characteristics" and the comparison to predicate devices, which serve as the "acceptance criteria" for a calibrator.
Here's a breakdown of the available information based on your request:
1. Table of Acceptance Criteria and Reported Device Performance
For calibrators, performance is primarily assessed by their ability to provide equivalent calibration to existing, approved calibrators. The key acceptance criterion is "equivalent correlation" between the new calibrators and the predicate device's calibrators.
Acceptance Criteria | Reported Device Performance |
---|---|
Equivalent correlation between: | Achieved: "equivalent correlation between predicate device kit calibrators and CEDIA Cardiac TDM Multi-Cals." |
- CEDIA Cardiac TDM Multi-Cals | |
- Predicate device kit calibrators for: | |
- Digoxin (K910642) | |
- Procainamide (K834464) | |
- N-acetylprocainamide (K830206) |
2. Sample size used for the test set and the data provenance
The document states, "Specific data on the performance of the test have been incorporated into the draft labeling in attachment 5." However, the actual sample size, details on the test set, and data provenance (e.g., country of origin, retrospective/prospective) are not provided in the excerpt.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
Not applicable/Not provided. For calibrators, "ground truth" is typically defined by reference methods or established values, not expert consensus in the same way it would be for a diagnostic image or clinical finding. The calibrators are "value assigned by comparison to the predicate device."
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
Not applicable/Not provided. This concept is generally used in studies involving human interpretation or subjective assessments, which is not the primary focus of calibrator validation.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
No. This is not an AI device, nor is it a diagnostic device that humans interpret. Therefore, an MRMC study and AI assistance effect size are not applicable.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
Yes, in essence. The testing of the calibrators themselves against predicate calibrators constitutes a "standalone" evaluation of their performance in achieving equivalent calibration. There is no "human-in-the-loop" component in the calibrator's function itself. The calibrator's performance is objective against an established reference.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)
The "ground truth" for the CEDIA Cardiac TDM Multi-Cals is established by comparison to the predicate device's kit calibrators. The predicate calibrators themselves would have had their values established through validated analytical methods and reference standards. The document states the new calibrators "have been value assigned by comparison to the predicate device to ensure correct assay calibration."
8. The sample size for the training set
Not applicable/Not provided. This is not a machine learning or AI device that requires a training set. The calibrators are manufactured reagents.
9. How the ground truth for the training set was established
Not applicable/Not provided. As stated above, there is no training set for this type of device.
