AI/ML Overview

Acceptance Criteria and Study for Mission Diagnostic Reagents

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for "Mission Diagnostic Reagents" are implicitly established by demonstrating performance equivalence to the predicate AVL calibrators. This equivalence is primarily shown through precision data and method comparison (correlation) studies.

Performance Characteristic	Acceptance Criteria (Implied by Predicate)	Reported Device Performance (Mission Reagents)
Precision (within-run, between-day)	Low %CV values, indicating consistent and reproducible measurements across different analyte levels. (Specific thresholds are not explicitly stated but are assumed to be comparable to or better than predicate performance).	Na: 0.33% - 1.15% %CVK: 0.58% - 3.65% %CVCl: 0.66% - 2.48% %CVCa: 1.72% - 2.21% %CVLi: 1.63% - 3.23% %CV
Method Comparison/Correlation (with AVL reagents)	Slope (m) close to 1, Intercept (b) close to 0, and R² close to 1, indicating strong linear correlation and agreement with predicate measurements.	Na: Slope (0.9859-1.024), Intercept (-3.42 to 2.13), R² (0.9985-0.999)K: Slope (0.9777-1.0094), Intercept (-0.02 to 0.12), R² (0.9984-0.9989)Cl: Slope (0.9669), Intercept (3.97), R² (0.9984)Ca: Slope (0.9004), Intercept (0.07), R² (0.9859)Li: Slope (1.0144), Intercept (-0.02), R² (0.9940)

The study aims to demonstrate that Mission reagents perform comparably to equivalent AVL reagents on AVL electrolyte instruments.

2. Sample Size Used for the Test Set and Data Provenance

Precision Test Set Sample Size (N):
- For Na, K, Cl (AVL 983, Table 1): N values range from 44 to 48 for each analyte at each of three QC levels.
- For Na, K, Ca (AVL 984, Table 2): N values range from 49 to 51 for each analyte at each of three QC levels.
- For Na, K, Li (AVL 985, Table 3): N values range from 47 to 48 for each analyte at each of three QC levels.
- Total N for precision is difficult to calculate exactly without knowing if some measurements overlap, but it is in the hundreds.
Correlation Test Set Sample Size (N):
- Na: 153 for 983, 135 for 984, 161 for 985.
- K: 153 for 983, 135 for 984, 162 for 985.
- Cl: 151 for 983.
- Ca: 134 for 984.
- Li: 132 for 985.
- Total N for correlation is in the hundreds for each specific analyte/instrument combination.
Data Provenance: The document does not specify the country of origin. The data is prospective, generated specifically for this 510(k) submission.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This type of submission for in-vitro diagnostic (IVD) calibrators does not typically involve human experts establishing ground truth in the way a medical imaging AI study would. The "ground truth" here is the performance of the predicate, commercially available AVL calibrators, and the accuracy of the AVL electrolyte analyzers themselves. The study compares the new device's performance to this established gold standard.

4. Adjudication Method for the Test Set

Not applicable for this type of IVD calibrator study. Adjudication by human experts is not typically a component of performance evaluation for analytical precision and method comparison studies for calibrators. The results are quantitative and compared statistically.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. This type of study is relevant for diagnostic imaging interpretation or other scenarios involving human interpretation of results, not for the performance of IVD calibrators.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done

Yes, this is a standalone performance study. The "device" in question (Mission Diagnostic Reagents) is an in-vitro diagnostic reagent, and its performance is evaluated directly on an instrument (AVL 98X Electrolyte Analyzers) without human interpretation affecting the raw analytical results. The outcome is quantitative data (e.g., %CV, slope, intercept).

7. The Type of Ground Truth Used

The ground truth for this device is the performance of the legally marketed predicate AVL calibrators. The study design directly compares the Mission reagents against these predicate reagents, with the assumption that the predicate reagents represent the accepted standard for accurate calibration on the AVL 98X analyzers. The "correlation with AVL Reagents" section explicitly states "Y = AVL results, X = Mission results," confirming the predicate AVL results are the reference.

8. The Sample Size for the Training Set

No explicit "training set" is mentioned in the context of this 510(k) summary. The study describes performance verification. IVD calibrators do not typically involve machine learning requiring a separate training set. The "samples" referenced are those used for the precision and correlation studies described above, which are test sets for performance evaluation.

9. How the Ground Truth for the Training Set Was Established

Not applicable, as no described "training set" in the machine learning sense is used for this device. The "ground truth" for the performance evaluation set (comparison with predicate AVL reagents) is established by the accepted analytical performance characteristics of those predicate reagents.

Mission uses a similar composition, description and packaging as that used by AVL in its . products, as shown in the packaging section of this submission.
Performance equivalence was shown in the following manner: .
- Through a method comparison where results obtained on an equivalent AVL o analyzer, calibrated with Mission calibrating products and compared with results obtained on the same analyzer calibrated with AVL calibrating products.
- Through a precision study where Mission products were installed on an equivalent O AVL analyzer and samples were measured minimally twice a day for 9 days.

A summary of the results of these studies follows:

Performance Characteristics:

Precision Data

Precision data were collected from the analysis of three levels of control materials, measured three times within a run, two runs minimally per day for nine days on each AVL analyzer calibrated with all Mission reagents.

Correlation with AVL Reagents

Correlation data were obtained from human serum samples for Na, K, Cl, Ca, and Li. Serum was first spiked with LiCI to obtain a base Li concentration. Samples were then spiked to yield varying spiked with Librain a bace in of the measuring analytes. The serum samples were measured on each AVL analyzers calibrated with Mission reagents for 2 runs and Calibrated with AVL reagents for 2 runs each test day.

Linear regression analysis was performed using Mission data as the independent X variable and AVL as the dependent Y variable in the equation Y = mX +b
