Note: The document directly states the results of the performance studies rather than explicitly listing "acceptance criteria." The acceptance criteria listed above are implied based on common regulatory expectations for in vitro diagnostic devices and the fact that the device received 510(k) clearance, indicating its performance was deemed acceptable for its intended use.
2. Sample Size and Data Provenance
- Test Set Sample Size:
- Method Comparison: 105 serum samples.
- Precision: Not explicitly stated as a "test set" for precision, but control materials were used. Control I, Control II, and a third control (spiked with Beta-2 Microglobulin) were run in duplicate twice a day over twenty days.
- Linearity, Limit of Quantification, Interference: Sample sizes for these specific studies are not explicitly provided in the text beyond the control materials or general statements about the analytes tested.
- Data Provenance: Not explicitly stated (e.g., country of origin, retrospective/prospective). The study was conducted by Biokit S.A. in Spain. Therefore, it is likely the data was generated in Spain or a similar geographical region. The text does not specify if the studies were retrospective or prospective, but assay performance studies are typically prospective evaluations.
3. Number of Experts and Qualifications for Ground Truth
Not applicable. This device is an in vitro diagnostic assay that measures a biomarker concentration. Ground truth is established by the analytical method itself (e.g., accuracy against a reference method or known concentrations) rather than expert interpretation of images or clinical data.
4. Adjudication Method for the Test Set
Not applicable. As described above, this is an analytical performance study for an in vitro diagnostic assay, not a study requiring human adjudication of results or interpretations.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study
Not applicable. This is an analytical performance study for an in vitro diagnostic assay. It does not involve human readers interpreting cases or AI assistance.
6. Standalone (Algorithm Only) Performance
Yes, the studies described are for the standalone performance of the Quantia Beta-2 Microglobulin assay on the Abbott AEROSET® instrument. There is no human-in-the-loop component mentioned in these performance evaluations.
7. Type of Ground Truth Used
- Method Comparison: The predicate device, IL Test Beta-2-Microglobulin, served as the comparative "ground truth" or reference for evaluating performance equivalence.
- Precision: Ground truth was established by the known concentrations of Beta-2 Microglobulin in the control materials (e.g., purified Beta-2 Microglobulin for spiking, or characterized control levels).
- Linearity, Limit of Quantification, Interference: Ground truth was based on known concentrations of the analyte and interferents, or reference measurements.
8. Sample Size for the Training Set
Not applicable. The Quantia Beta-2 Microglobulin is an immunoturbidimetric assay, not an AI or machine learning algorithm that requires a "training set" in the conventional sense. The assay's performance is determined by its chemical and optical reagents and the instrument's calibration and measurement principles.
9. How the Ground Truth for the Training Set Was Established
Not applicable. As noted above, this device does not utilize a training set in the context of machine learning. The "ground truth" for calibrating and developing such an assay typically involves using highly purified standards of known concentration and validating methods against established reference procedures.

{1}------------------------------------------------
Summary of Performance Data:
In a method comparison study 105 serum samples with Beta-2 Microglobulin levels ranging from 1.01 to 101.1 mg/L were evaluated on the Abbott AEROSET® instrument. The slope was 0.876 and the correlation coefficient (r) was 0.9986 for the Quantia Beta-2 Microglobulin versus the predicate device.
Within run precision was assessed using the Quantia PROTEINS Controls I and II (low and high) and a third control spiked with pure Beta-2 Microglobulin at 10-15 mg/L, run in duplicate twice a day over twenty days (following the NCCLS EP5-A guideline), on the Abbott AEROSET® instrument. Control I gave a CV of 1.1 % (at a mean of 1.00 mg/L), Control II gave a CV of 0.9 % (at a mean of 5.46 mg/L) and the third control gave a CV of 0.9 % (at a mean of 13.61 mg/L). Total run precision gave a CV of 1.9% for Control I, 1.3% for Control II and 1.1% for the third control.
Linearity was assessed according to NCCLS EP6-A guideline. The assay was found to be linear within the following ranges:
- 0.25 to 16 mg/L without the automatic rerun capability.
- 0.02 to 100 mg/l with the automatic rerun capability.
The Limit of Quantification was defined as the minimum quantity of analyte that can be measured with a within-run CV below 20% and an error below ± 20 %. Without the automatic rerun capability, the Limit of Quantification for the Beta-2 Microglobulin assay is 0.25 mg/L and, with the automatic rerun capability, 0.02 mg/L.
The Interference study was assessed using the NCCLS guideline EP7-A. Interference testing is summarized as follows:
No significant interference from lipemia up to sample absorbance of 2.1 AU/cm at 660 nm. No significant interference from triglycerides up to concentrations of 1300 mg/dL. No significant interference from bilirubin up to concentrations of 20 mg/dL. No significant interference from haemoglobin up to concentrations of 480 mg/dL. RF interference is below 10% up to 288 IU/mL.
