Intended Use
The IgX PLEX™ Rheumatoid Arthritis Qualitative Assay and SQiDworks™ Diagnostics Platform is an in vitro diagnostic test system for the qualitative detection of the IgA and IgM classes of Rheumatoid Factors, and the IgG class of anti-cyclic citrullinated peptide antibodies (CCPproprietary third generation equivalent formulation) in human serum specimens. The IgX PLEXTM Rheumatoid Arthritis Qualitative Assay is intended for use in clinical laboratories as an aid in the diagnosis of Rheumatoid Arthritis in conjunction with other laboratory and clinical findings, and requires the SQiDworks™ Diagnostics Platform.
Device Description
The device consists of the IgX PLEX™ Rheumatoid Arthritis Qualitative Assay (RL1 kit) and the SQiDworks™ Diagnostics Platform (the Platform); the Platform incorporates the SQiDworks™ Integrated Software (the Software). The Platform is a multiplex immunoassay instrument that fully automates the process of a specific IgX PLEX™ Assay from serum transfer to reporting of all assay markers for each individual patient sample. Once the assay's biochemical reactions have completed, the instrument automatically performs a multi-color fluorescent scan of each well in the microarray, analyzes the data, and generates a report containing qualitative results for all assay markers. The SQiDworks Diagnostics Platform also includes numerous internal quality checks and user safety features with fail-safe and interlock mechanisms. The instrument integrates an automated pipetting station, a fluorescent scanner, washing and drying stations, and other ancillary hardware components using dedicated instrument control. In addition, the software provides scheduling, self-verification, data acquisition, data management, analysis algorithms and reporting software. Results for each patient sample from the IgX PLEXIM Rheumatoid Arthritis Qualitative Assay and the SQiDworks™ Diagnostics Platform are obtained simultaneously for cach of the three assay markers: RF IgM, RF IgA and CCP IgG using the results from one well containing one aliquot of the patient's serum. Results are reported independently. The IgX PLEXIM Rheumatoid Arthritis Qualitative Assay (RL1) kit consists of two boxes (with different temperature requirements) of components as described below.

No
The document describes automated data analysis and algorithms but does not mention AI, ML, or deep learning. The performance studies are based on traditional metrics and comparisons to predicate devices, not on training or test sets typically associated with AI/ML models.

No.
The device is an in vitro diagnostic test system used to aid in the diagnosis of Rheumatoid Arthritis by detecting specific antibodies; it does not directly treat or prevent a disease.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "an in vitro diagnostic test system" and is "intended for use in clinical laboratories as an aid in the diagnosis of Rheumatoid Arthritis".

No

The device description explicitly states that the device consists of both an assay kit and a "Platform" which is described as a "multiplex immunoassay instrument" that includes automated pipetting, a fluorescent scanner, washing and drying stations, and other ancillary hardware components. While it includes software, it is not solely software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the device is an "in vitro diagnostic test system" for the detection of specific antibodies in human serum specimens. It also states it is intended for use in clinical laboratories as an aid in the diagnosis of Rheumatoid Arthritis.
  • Device Description: The description details a system that analyzes biological samples (human serum) to provide diagnostic information.
  • Clinical Context: The device is intended for use in clinical laboratories and the results are used in conjunction with other findings for diagnosis.

These points clearly align with the definition of an In Vitro Diagnostic device.

IgX PLEX RL1 Microarray Plate

The RL1 microarray plate consists of an array of protein and antibody replicate spots, covalently bound to the surface of coated glass within each well of a standard 96-well assay plate. All wells have the identical configuration of microarray elements, containing:

  • . Capture spots for Rheumatoid Factor Fc and CCP.
  • Internal normalization curve and control spots for internal consistency . confirmation.

The outer plate holder is labeled with a barcode indicating the assay type and lot number which is read by the platform.

Reporter Mix

The reporter mix is comprised of diluted fluorescently labeled marker antibodies. There is a marker antibody which is specific to each antibody of interest. In the case of the RL1 assay, the labeled markers are anti-human immunoglobulin antibodies (for example mouse o-hIgM). Each type of marker antibody is labeled with a dye in a different spectral range.

Calibrators/Standards

The external calibrators (standards) are eight dilutions of a sample derived from human sera containing an appropriate representation of each of the analytes to be reported. The assay standards (secondary standards) for RF (IgA and IgM) are traceable to the WHO/First British Standard 64/2 (primary standards) and internally calculated in IU/mL. The CCP IgG results are internally calculated in U/mL and are comparable to other assays on the market. The quantitative results are converted to qualitative results (positive and negative), based on assay-specific cutoff values. No. dilutions or reconstitutions are needed.

Controls

The positive and negative control samples are derived from human sera. The platform treats the controls as samples and does not perform any quality assessment based on the

results. Although expected results for each applicable analyte of each control are provided, each lab is expected to follow their own quality procedures for assessing controls.

Sample Diluent

The sample diluent is a proprietary buffer mix optimized to the requirements of the platform.

Wash Buffer Concentrates

Specific buffer compositions for each wash procedure. The concentrate must be diluted prior to use.

CDROM

One CD is included in each shipment. The contents are a database of lot specific calibration data for each lot in the shipment and the documentation for the user's convenience.

Intended Use 807.92 (a)(5):

The IgX PLEX™ Rheumatoid Arthritis Qualitative Assay and SQiDWorks™M Diagnostics Platform is an in vitro diagnostic test system for the qualitative detection of the IgA and IgM classes of Rheumatoid Factors and the IgG class of anti-cyclic citrullinated peptide antibodies (CCP-proprietary third generation equivalent formulation) in human serum specimens.
