The IGG method is an in vitro diagnostic test for the quantitative measurement of immunoglobulin G in human serum, heparinized plasma, cerebrospinal fluid (CSF) and urine on the Dimension Vista® System. Measurements of IgG aid in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.

PROT3 CON is an assayed, low level intralaboratory quality control for assessment of precision and analytical bias on the Dimension Vista System in the determination of α Microglobulin (A1MIC), specialty Albumin (sALB), Immunoglobulin G (IGG -C), Immunoglobulin G (IGG-U)** and Microalbumin (MALB). * For Cerebrospinal fluid (CSF) ** For urine
Dimension Vista® System Immunoglobulin G Flex® reagent cartridge: Proteins contained in human body fluids from immune complexes in an immunochemical reaction with specific antibodies. These complexes scatter a beam of light passed through the sample. The intensity of the scattered light is proportional to the concentration of the respective protein in the sample. The result is evaluated by comparison with a standard of known concentration.

The provided document is a 510(k) premarket notification for in vitro diagnostic devices, namely the Dimension Vista® System IGG Flex® reagent cartridge, Protein 1 Calibrator, and Protein 3 Control. It states that these devices are substantially equivalent to legally marketed predicate devices. This type of submission does not typically include detailed studies with acceptance criteria and device performance in the format of a clinical trial for an AI/ML medical device. Instead, it focuses on demonstrating analytical performance (e.g., correlation, precision, analytical bias) for a laboratory diagnostic system.
Therefore, the requested information about acceptance criteria, device performance, sample sizes for test and training sets, data provenance, expert adjudication, MRMC studies, standalone performance, and how ground truth was established is not present in the provided text.
The document primarily makes claims of substantial equivalence to predicate devices based on intended use and analytical studies, rather than reporting on a clinical effectiveness study with defined acceptance criteria for diagnostic accuracy, sensitivity, or specificity in the way an AI/ML device might.
Here's a breakdown of what can be extracted and what is missing:
1. Table of Acceptance Criteria and Reported Device Performance
Not explicitly provided. The document states that "studies included in this submission demonstrate correlation to and equivalent performance between the predicate Beckman Coulter IMMAGE® Immunochemistry System Urine Immunoglobulin G for urine sample matrix and the predicate N Antisera to Human Immunoglobulins (IgG IgA, and IgM) on the BN ProSpec® System for the addition of a pre-reaction step to the Dimension Vista® IGG-C assay."
This indicates that correlation and equivalent performance were the acceptance criteria, but the specific metrics (e.g., correlation coefficient thresholds, mean difference limits) and the resultant device performance values are not detailed in this summary.
2. Sample Size Used for the Test Set and Data Provenance
Not provided. The summary mentions "studies" but does not give details about the sample sizes of patients or samples used in these studies, nor their country of origin or whether they were retrospective or prospective.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications
Not applicable/Provided. For an in vitro diagnostic device measuring immunoglobulin G, the "ground truth" would typically be established by a reference method or known concentrations of analytes in control materials, not by expert interpretation of images or clinical data. Therefore, the concept of "experts" in this context is not relevant.
4. Adjudication Method for the Test Set
Not applicable/Provided. Adjudication methods (e.g., 2+1) are usually relevant for human expert interpretation and resolving discrepancies, which is not pertinent to the analytical performance of an in vitro diagnostic assay.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No. MRMC studies are associated with diagnostic imaging or other interpretive tasks where multiple human readers assess cases. This is an IVD device for quantitative measurement, so an MRMC study would not be applicable.
6. If a Standalone Performance (Algorithm Only Without Human-in-the-Loop Performance) Was Done
Yes, implicitly. The device is an in vitro diagnostic system designed to quantitatively measure Immunoglobulin G. Its performance is inherently "standalone" in that it processes samples and produces numerical results without human interpretive input into the measurement itself. The "correlation" and "equivalent performance" mentioned would be standalone analytical performance. However, specific metrics are not provided.
7. The Type of Ground Truth Used
Implicitly, reference methods or known concentrations. For an IVD device, the ground truth for performance studies is typically established by:
- Comparison to a legally marketed predicate device (as stated in the conclusion).
- Known concentrations of analytes in control samples or calibrators.
- Reference methods that are considered the gold standard for measuring the analyte.
The document states "correlation to and equivalent performance between the predicate...", suggesting the predicate device's results serve as the ground truth reference for comparison.
8. The Sample Size for the Training Set
Not applicable/Provided. This device is an analytical instrument and reagents, not an AI/ML algorithm that is "trained" on a dataset in the conventional sense. The "training set" concept is not relevant here.
9. How the Ground Truth for the Training Set Was Established
Not applicable/Provided. As mentioned, the concept of a "training set" with established ground truth is not applicable for this type of IVD device.
§ 866.5510 Immunoglobulins A, G, M, D, and E immunological test system.
(a)
Identification. An immunoglobulins A, G, M, D, and E immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the immunoglobulins A, G, M, D, an E (serum antibodies) in serum. Measurement of these immunoglobulins aids in the diagnosis of abnormal protein metabolism and the body's lack of ability to resist infectious agents.(b)
