EliA Cardiolipin IgA is intended for the in vitro semi-quantitative measurement of IgA antibodies directed to cardiolipin in human serum and plasma (heparin, EDTA, citrate) to aid in the diagnosis of antiphospholipid syndrome (APS) as well as thrombotic disorders related to systemic lupus erythematosus (SLE) in conjunction with other laboratory and clinical findings. EliA Cardiolipin IgA uses the EliA IgA method on the instruments Phadia 100.

Device Description

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 Phadia 100 and Phadia 250.

The conjugate for the EliA IgA method is mouse anti-human IgA beta-galactosidase, which uses 4-Methylumbelliferyl-BD-Galactoside as substrate.

The total IgA calibration is based on a set of six WHO-standardized IgA 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.

AI/ML Overview

The provided text describes the regulatory submission for the EliA™ Cardiolipin IgA Immunoassay and associated control devices. However, it does not contain any information about acceptance criteria or specific study results that prove the device meets such criteria.

The document primarily focuses on:

510(k) Summary details: Manufacturer, contact, device names, common name, classification, and date.
Intended Use Statements: Explicitly stating what the EliA Cardiolipin IgA device is designed to measure (IgA antibodies to cardiolipin) and its purpose (aiding in diagnosis of APS and thrombotic disorders related to SLE) on Phadia 100 and Phadia 250 instruments.
Special Conditions for Use: Prescription use only.
Special Instrument Requirements: Phadia 100/250 automated immunoassay analyzers.
General Description and Test Principle: Explains the fluorescence-immunoassay system, antigen coating, and methodology.
Device Comparison: States that the new device and predicate (Quanta Lite IgA ACA (HRP), K953366) are both non-competitive solid phase ELISAs used for similar diagnostic aids.
Laboratory Equivalence: Mentions that comparability is supported by a comparison study, clinically defined sera, and samples from healthy subjects, concluding with a statement of substantial equivalence.
FDA Correspondence: Official letter acknowledging receipt and approval of the 510(k) submission, confirming substantial equivalence and providing regulatory information.
Indications for Use Forms: Repeated forms for the main device and its associated positive and negative controls, reiterating their intended uses.

Therefore, I cannot provide the requested table of acceptance criteria and device performance, nor details about sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, standalone performance, or ground truth establishment based on the provided text.

The document states that a "comparison study between new and predicate device" and "results obtained for clinically defined sera" were used to support laboratory equivalence, but it does not present the data, the specific acceptance criteria, or the methodology of these studies.

Intended Use Statements of the New Device

Special condition for use statement

The device is for prescription use only.

Special instrument requirements

Phadia® 100/Phadia® 250 are fully automated immunoassay analyzers, which include software for evaluation of test results.

General Description of the New Device

The conjugate for the EliA IgA method is mouse anti-human IgA beta-galactosidase, which uses 4-Methylumbelliferyl-BD-Galactoside as substrate.

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

Test Principle of the New Device

The EliA Wells are coated with the following antigen:

Test	Antigen coated to the wells:
EliA Cardiolipin IgA Well	Bovine cardiolipin antigen and bovine β2-glycoprotein I as co-factor

If present in the patient's specimen, antibodies to the antigens mentioned above bind to their specific antigen. After washing away non-bound antibodies, enzyme-labeled antibodies against human IgA antibodies (EliA IgA Conjugate) are added to form an antibody-conjugate complex. After incubation, non-bound conjugate is washed away and the bound complex is inculated with a Development Solution. After stopping the reaction, the fluorescence in the reaction mixture is measured. The higher the response value, the higher the amount of antibody bound and detected in the sample tested. 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 ELISAs. Both IVDs are used as an aid in the diagnosis of antiphospholipid syndrome (APS) as well as thrombotic disorders related to systemic lupus erythematosus (SLE).

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.

§ 866.5660 Multiple autoantibodies immunological test system.

(a)
Identification. A multiple autoantibodies immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the autoantibodies (antibodies produced against the body's own tissues) in serum and other body fluids. Measurement of multiple autoantibodies aids in the diagnosis of autoimmune disorders (disease produced when the body's own tissues are injured by autoantibodies).(b)
Classification. Class II (performance standards).
