AI/ML Overview

This document describes the Diamond Diagnostics ISE Serum Standards and ISE Urine Standards, which are calibrators for medical devices. The document highlights the product's characteristics, intended use, and a comparison with a predicate device to demonstrate substantial equivalence.

1. Acceptance Criteria and Reported Device Performance

The acceptance criteria are implied by the target values for each analyte in the standards, with a defined tolerance range. The "reported device performance" refers to the target values that the manufactured calibrators are designed to meet and are verified against.

Diamond Diagnostics ISE Serum Standard Low:

AnalyteUnitsAcceptance Criteria (Target Value)Reported Device Performance (as designed)
Na+mmol/L130 ± 2130 ± 2
K+mmol/L3.5 ± 0.053.5 ± 0.05
Cl-mmol/L85 ± 285 ± 2

Diamond Diagnostics ISE Serum Standard High:

AnalyteUnitsAcceptance Criteria (Target Value)Reported Device Performance (as designed)
Na+mmol/L160 ± 2160 ± 2
K+mmol/L6 ± 0.056 ± 0.05
Cl-mmol/L120 ± 2120 ± 2

Diamond Diagnostics ISE Urine Standard Low:

AnalyteUnitsAcceptance Criteria (Target Value)Reported Device Performance (as designed)
Na+mmol/L50 ± 250 ± 2
K+mmol/L10 ± 0.210 ± 0.2
Cl-mmol/L50 ± 250 ± 2

Diamond Diagnostics ISE Urine Standard High:

AnalyteUnitsAcceptance Criteria (Target Value)Reported Device Performance (as designed)
Na+mmol/L200 ± 3200 ± 3
K+mmol/L100 ± 2100 ± 2
Cl-mmol/L180 ± 2180 ± 2

The study demonstrates that the manufactured standards are tested to assure they meet these target values within the predetermined acceptance criteria.

2. Sample size used for the test set and the data provenance

  • Test Set Description: The document refers to testing "reagents analytically prior to bottling" and "analytically during the bottling process and prior to release to stock for distribution." Additionally, "Six replicates of each sample are tested analytically for the electrolytes."
  • Sample Size: Six replicates of each standard (ISE Serum Standard Low, ISE Serum Standard High, ISE Urine Standard Low, ISE Urine Standard High) were tested.
  • Data Provenance: The data appears to be prospective, generated during the manufacturing and quality control process of the Diamond Diagnostics ISE Standards. The country of origin is not explicitly stated but implied to be the US given the FDA submission.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This section is not applicable. The device is a calibrator, and its performance is evaluated against chemical reference standards and methods, not expert human interpretation.

4. Adjudication method for the test set

This section is not applicable. The evaluation relies on objective analytical measurements rather than subjective human assessment requiring adjudication.

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

This section is not applicable. The device is a chemical calibrator, not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

This section is not applicable as the device is a chemical calibrator. However, the performance of the calibrator itself is assessed in a "standalone" manner through analytical testing of its constituent analytes using specified reference methods.

7. The type of ground truth used

The ground truth for the test set is established by:

  • Reference Standard Materials: NIST (National Institute of Standards and Technology) salts (NIST 919b for Na and Cl, NIST 918b for K) which are gravimetrically prepared.
  • Reference Methods:
    • IL 943 Flame Photometry for Na+ and K+.
    • SAT-500 Salt Analyzer (Titrimetric method) for Cl-.

8. The sample size for the training set

This section is not applicable. The device is a calibrator, and its formulation and target values are based on established chemical principles and comparison to predicate devices, not a 'training set' in the machine learning sense. The "training" for such a device would be the formulation and manufacturing process designed to consistently achieve the specified concentrations.

9. How the ground truth for the training set was established

This section is not applicable. As explained in point 8, there isn't a "training set" in the traditional sense for this type of device. The "ground truth" for the calibrator's target values is established by:

  • Gravimetric Preparation from NIST Standards: Analytes are derived from NIST certified reference materials.
  • Analytical Verification using Reference Methods: The final concentrations are verified using established and accurate analytical methods (Flame Photometry and Titrimetry).
  • Matching Predicate Device Values: The target values were chosen to match those of the predicate ADVIA ISE Serum Standards and ISE Urine Standards.

Stability:

Accelerated (high temperature) stress test was conducted to support the stability claim of 24 months when stored at 18℃ to 25℃. Heat stressed reagents showed that the ISE Serum Standards and ISE Urine Standards parameters remained within specification. Open-Vial Stability was conducted to support the claim of 30 days at 18-25℃. Open-vial reagents showed that the ISE Serum Standards and ISE Urine Standards parameters remained within specification. Real time stability studies are in progress and will commence at 6 month intervals for 2 years at 18°C and 25°C. The solutions will be tested analytically for the electrolytes using reference methods. Flame Photometry will be used for the Na " and K . Silver/Silver Chloride Titration method is used for the Cl. Functional performance for calibration and control testing will likewise be performed.

Traceability:

All testing for analytes were conducted using Standards gravimetrically prepared from NIST salts. Testing was also conducted using reference methods.
