## Device Story
In vitro diagnostic immunoassay; detects antinuclear IgG antibodies in human serum/plasma. Uses wells coated with recombinant U1RNP, SS-A/Ro, SS-B/La, Centromere B, Scl-70, Jo-1, and native Sm proteins. Patient sample added to wells; specific antibodies bind to antigens. Unbound antibodies washed away; enzyme-labeled anti-human IgG conjugate added. After incubation and washing, development solution added; fluorescence measured. Higher fluorescence indicates higher IgG concentration. Results compared to calibrators to determine qualitative status (Ratio). Used on ImmunoCAP 100 or 250 analyzers in clinical laboratories. Output aids clinicians in diagnosing systemic autoimmune rheumatic diseases. Benefits include automated, standardized detection of multiple autoantibodies simultaneously.
## Clinical Evidence
Clinical performance evaluated using 137 samples from patients with defined autoimmune diseases (SLE, Sjögren's, MCTD, scleroderma, myositis, overlap) and 50 healthy controls. Clinical sensitivity and specificity were 100%. Method comparison against QuantaLite ENA 6 (n=137) and IIF HEp-2 (n=14) showed 100% overall agreement. Analytical precision (intra/inter-assay) showed CVs < 6% for positive samples. No hook effect observed up to 6000 μg/L. No significant interference from bilirubin, hemoglobin, chyle, or rheumatoid factor.
## Technological Characteristics
Solid-phase ELISA using 48-microwell plates. Antigens: human recombinant U1RNP, SS-A/Ro, SS-B/La, Centromere B, Scl-70, Jo-1, and native Sm. Conjugate: β-Galactosidase anti-human IgG. Signal: fluorescence (4-Methylumbelliferyl-β-D-galactoside substrate). Automated operation on ImmunoCAP 100/250 platforms. Calibrators traceable to WHO IRP 67/86. Reaction temperature: 37°C.
## Regulatory Identification
An antinuclear antibody immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoimmune antibodies in serum, other body fluids, and tissues that react with cellular nuclear constituents (molecules present in the nucleus of a cell, such as ribonucleic acid, deoxyribonucleic acid, or nuclear proteins). The measurements aid in the diagnosis of systemic lupus erythematosus (a multisystem autoimmune disease in which antibodies attack the victim's own tissues), hepatitis (a liver disease), rheumatoid arthritis, Sjögren's syndrome (arthritis with inflammation of the eye, eyelid, and salivary glands), and systemic sclerosis (chronic hardening and shrinking of many body tissues).

#### Intended Use Statement of the New Device
EliA Symphony Immunoassav is intended for the in vitro qualitative measurement of antinuclear IgG antibodies in human serum and plasma (heparin, EDTA and citrate). EliA Symphony Immunoassay is based on human recombinant U1RNP (RNP 70, A, C). SS-A/Ro (60 kDa. 52 kDa), SS-B/La, Centromere B, Sc1-70, Jo-1 proteins and native purified Sm proteins as antigen and is useful as an aid in the clinical diagnosis of patients with systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), Sjögren's syndrome, scleroderma and polymyositis/dermatomyositis, in conjunction with other laboratory and clinical findings. EliA Symphony Immunoassay uses the EliA IgG method on the instrument ImmunoCAP 100 and ImmunoCAP 250.
EliA ANA Control is intended for laboratory use in monitoring the performance of in vitro measurement of antinuclear antibodics (ANA) with ImmunoCAP 100 or ImmunoCAP 250 using the EliA IgG method.
#### Special condition for use statement
The device is for prescription use only.
#### Special instrument requirements
ImmunoCAP 100 / ImmunoCAP 250 are fully automated immunoassay analyzers, which include software for evaluation of test results.
### General Description of the New Device
The new device belongs to a fully integrated and automated system for immunodiagnostic testing. It comprises a Fluorescence-Immunoassay test system using EliA single wells as the solid phase and is intended to be performed on the instruments ImmunoCAP 100 and ImmunoCAP 250. The conjugate for the EliA IgG method is mouse anti-human IgG beta-galactosidase, which uses 4-Methylumbellifery|-8D-Galactoside as substrate. The total IgG calibration is based on a set of six WHOstandardized IgG Calibrators derived from human serum. They are used to establish an initial calibration curve, which may be used for up to 28 days on additional assays and can be stored by the instrument. Each additional assay includes calibrator (curve) controls that have to recover in defined ranges to ensure that the stored calibration curve is still valid. The Fluorescence-Immunoassay test system includes test-, method specific and general reagents that are packaged as separate units.
{2}------------------------------------------------
### Test Principle of the New Device
The EliA Symphony Wells are coated with human recombinant U1RNP (RNP 70, A, C), SS-A/Ro (60 kDa, 52 kDa), SS-B/La, Centromere B, Scl-70 and Jo-1 proteins, native purified Sm proteins. If present in the patient's specimen, antibodies to the antigens bind to their specific antigen. After washing away non-bound antibodies, enzyme-labeled antibodies against human IgG antibodies (EliA IgG Conjugate) are added to form an antibody-conjugate complex. After incubation, non-bound conjugate is washed away and the bound complex is incubated with a Development Solution. After stopping the reaction, the fluorescence in the reaction mixture is measured. The higher the response value, the more specific IgG is present in the specimen. To evaluate test results, the response for patient samples is compared directly to the response for calibrators.
### Device Comparison
The new and the predicate device both represent non-competitive solid phase EIAs. The predicate device for the demonstration of the Centromere B antigen was an IIF, NOVA Lite™ HEp-2 assay. These IVDs are used as an aid in the diagnosis of Systemic Lupus Erythematosus (SLE) and related connective tissue diseases, in conjunction with other laboratory and clinical findings.
### Laboratory equivalence
The comparability of predicate device and new device is supported by a data set including
- · results obtained within a comparison study between new and predicate devices
- · results obtained for clinically defined sera
- · results obtained for samples from apparently healthy subjects (normal population).
In summary, all available data support the conclusion that the new device is substantially equivalent to the predicate devices.
