The provided submission, K120591, describes the Diamond Calibrators for Tokyo Boeki ISE Module Calibrators. This is a medical device for in-vitro diagnostics. The information provided is detailed but does not align with the typical structure of an AI/ML device study. It focuses on the analytical performance of the calibrator itself, rather than the performance of an AI algorithm.
Therefore, many of the requested sections about AI/ML device studies (e.g., sample size for test set, number of experts, adjudication method, MRMC study, standalone performance, training set details) are not applicable to this submission.
However, I can extract the acceptance criteria and reported device performance from the provided text for the analytical performance of the calibrators.
Acceptance Criteria and Reported Device Performance
Device: Diamond Calibrators for Tokyo Boeki ISE Module Calibrators
Intended Use: To provide calibration points for Na+, K+, and Cl- electrodes on specific Tokyo Boeki instruments in both Human Serum and Human Urine modes.
Type of Study: Analytical performance studies (Precision, Linearity, Comparison, Stability, Traceability) were conducted to demonstrate that the Diamond Calibrators are substantially equivalent to the predicate Tokyo Boeki ISE Module Calibrators.
Ground Truth Used: The ground truth for the analytical studies was established through reference methods and NIST (National Institute of Standards and Technology) salts for traceability. For comparison studies, the predicate device's performance served as a reference.
Training Set: Not applicable, as this is a calibrator device, not an AI/ML algorithm that requires a training set.

Note: For Serum Precision (Within Run), Cl- shows 1.06 at mid and 1.2 at high %CV, while the specification is <1 for low/mid and <2 for high. The table entry "Spec" for Cl- is "<1" for Low and Mid, and "<1" for High, which seems inconsistent with the other analytes. However, given the "P/F: Pass" declaration, it's assumed the specifications were met as intended, or the "<1" high spec for Cl- was a typo and should have been "<2" like the Run-to-Run. Based on contextual interpretation, the results passed.
1. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective):
- Precision:
- For within-run precision: 20 consecutive samples for each of three levels (low, mid, high) for both serum and urine matrices, and for each of Na+, K+, Cl-. This totals 20 * 3 = 60 measurements per analyte per matrix. Example: 60 measurements for Na+ in serum.
- For run-to-run precision: 5 consecutive samples for each of three levels (low, mid, high) for both serum and urine matrices, and for each of Na+, K+, Cl-. This totals 5 * 3 = 15 measurements per analyte per matrix. Example: 15 measurements for Na+ in serum.
- Linearity:
- Serum: 39 observations for Na+ and Cl+, 66 observations for K+.
- Urine: 33 observations for Na+, 66 observations for K+, and 73 observations for Cl+.
- Comparison Studies:
- Serum: 33 observations for Na+, 57 observations for K+, 39 observations for Cl+.
- Urine: 42 observations for Na+, 62 observations for K+, 73 observations for Cl+.
- Data Provenance: Not specified, but generally, such analytical studies are conducted in a controlled laboratory environment. Retrospective/prospective is not applicable as this is not a clinical study on patient data.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience):
Not applicable. The ground truth for this calibrator device performance relies on established analytical methods, reference materials (NIST salts), and comparison to a legally marketed predicate device, not expert human interpretation.
3. Adjudication method (e.g. 2+1, 3+1, none) for the test set:
Not applicable. Adjudication methods refer to reconciling differences among human readers for image interpretation or diagnosis, which is not relevant for this analytical device testing.
4. 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:
Not applicable. This is an in-vitro diagnostic calibrator, not an AI-powered diagnostic device used by human readers.
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This is an in-vitro diagnostic calibrator, not an AI algorithm. Its performance is measured directly through analytical tests.
6. The type of ground truth used (expert concensus, pathology, outcomes data, etc):
The ground truth was established through:
- Reference methods (e.g., IL 943 for flame photometry, Corning 925/SAT-500 Salt Analyzer for titrimetric methods).
- NIST (National Institute of Standards and Technology) salts (919a, 918a) for traceability and determination of analyte values.
- Comparison to the predicate device, K040958 (Tokyo Boeki ISE Module Calibrators).
7. The sample size for the training set:
Not applicable. This is a calibrator device, not an AI/ML algorithm that requires a training set.
8. How the ground truth for the training set was established:
Not applicable, as there is no training set for this device.

Dear Ms. Cruz:
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. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820).
This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
