Intended Use

EliA™ dsDNA is intended for the in vitro quantitative measurement of IgG antibodies directed to dsDNA in human serum and plasma (heparin, EDTA, citrate) as an aid in the diagnosis of systemic lupus erythematosus (SLE) in conjunction with other laboratory and clinical findings. EliA™ dsDNA 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 antibodies (ANA) with ImmunoCAP 100 or ImmunoCAP 250 using the EliA IgG method.

Device Story

Fully automated fluorescence-immunoassay system for immunodiagnostic testing. Inputs: human serum or plasma samples. Principle: EliA wells coated with double-stranded plasmid DNA capture anti-dsDNA antibodies; mouse anti-human IgG beta-galactosidase conjugate added; 4-Methylumbelliferyl-BD-Galactoside substrate used for fluorescence detection. Instrument (ImmunoCAP 100/250) measures fluorescence; response compared to WHO-standardized IgG calibration curve. Used in clinical laboratories by trained personnel. Output: quantitative IgG antibody levels. Results aid clinicians in SLE diagnosis alongside other clinical findings. System includes automated software for result evaluation and calibration curve storage (up to 28 days).

Clinical Evidence

Comparison study performed between the new device and the predicate device. Data set included results from clinically defined sera and samples from apparently healthy subjects (normal population).

Technological Characteristics

Fluoroenzyme immunoassay; wells coated with double-stranded plasmid DNA. Detection via β-galactosidase-labeled anti-human IgG conjugate. Fluorescence measured at 37°C. Fully automated on ImmunoCAP 100/250 platforms. Modular reagent format. Calibration traceable to WHO IRP 67/86. Software-controlled calibration curve storage (28 days).

Indications for Use

Indicated for the in vitro quantitative measurement of IgG antibodies to dsDNA in human serum and plasma as an aid in the diagnosis of systemic lupus erythematosus (SLE).

Regulatory Classification

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).

Predicate Devices

• DPC anti-DNA (K874873)

### Intended Use Statement of the New Device

EliA dsDNA is intended for the in vitro quantitative measurement of IgG antibodies directed to dsDNA in human serum and plasma (heparin, EDTA, citrate) as an aid in the clinical diagnosis of systemic lupus erythematosus (SLE) in conjunction with other laboratory and clinical findings. EliA dsDNA Immunoassav 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 antibodies (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-Methylumbelliferyl-BD-Galactoside as substrate. The total IgG calibration is based on a set of six WHO-standardized IgG Calibrators derived from human serum. They are used to establish an initial calibration curve. which mav 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.

#### Test Principle of the New Device

The EliA dsDNA Wells are coated with double-stranded plasmid DNA. If present in the patient's specimen, antibodies to dsDNA 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

{2}------------------------------------------------

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 are used as an aid in the diagnosis of Systemic Lupus Erythematosus (SLE) 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 device
- · results obtained for clinically defined sera
- · results obtained for samples from apparently healthy subjects (normal population).

In summary, all available data support that the new device is substantially equivalent to the predicate device.
