- Repeatability (within-run precision):
- 3 specimens (low, medium, high concentration)
- 2 controls
- Each tested 20 times.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of information is generally not applicable to in vitro diagnostic (IVD) assays for quantitative chemical measurements. The "ground truth" for these studies is typically established by measurements from a well-characterized reference method or a predicate device, rather than expert consensus on images or clinical assessments. The studies performed here compare the device to a "commercial reagent taken as reference" (predicate device K061575) and uses established laboratory protocols (CLSI, Valtec).
4. Adjudication Method for the Test Set
Not applicable. The "ground truth" is derived from quantitative measurements by reference methods, not subjective assessments requiring adjudication.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is typically performed for diagnostic imaging devices where human readers interpret images, sometimes with AI assistance. This document describes a clinical chemistry analyzer and reagents, which do not involve human interpretation of images in the same way.
6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study
Yes, the studies described are standalone performance evaluations of the assay system (reagent and instrument). The performance metrics (detection limits, precision, linearity, method comparison, stability) reflect the algorithm's and the physical assay's performance without direct human interpretation influencing the measurement results. The human input is in setting up the system, running controls, and interpreting the numerical output, but the analytical measurement itself is automated.
7. Type of Ground Truth Used
- Reference Method/Predicate Device Comparison: For the method comparison study, the "ground truth" was established by measurements from a "commercial reagent taken as reference" (Olympus Calcium Arsenazo reagent, K061575).
- CLSI/NCCLS Protocols: Other performance parameters (detection limit, quantitation limit, precision, linearity) were evaluated against established CLSI/NCCLS and Valtec protocols, which define acceptable measurement performance characteristics. These protocols inherently define the "truth" in terms of statistical and analytical performance.
8. Sample Size for the Training Set
Not applicable. This device is a quantitative in vitro diagnostic reagent and assay system, not an AI/machine learning model that requires a training set in the conventional sense. The development of the reagents and assay parameters is based on chemical and analytical principles, and the performance is validated through the studies listed.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no training set for this type of IVD device.
