Intended Use

Enzyme linked immunosorbent assay method for the semi-quantitative determination of specific IgA rheumatoid factor (RF) antibodies in human serum. Uses: The results of the RF IgA assay can be used as an aid in the diagnosis of rheumatoid arthritis (RA) when supported by other laboratory and clinical investigations. Levels of these autoantibodies are one indicator in a multi-factorial diagnostic regime. The assay may be used on the Hycor Hy. Tec Automated EIA instrument. For in vitro diagnostic use only.

Device Story

Autostat II Rheumatoid Factor IgA ELISA is an in vitro diagnostic assay for detecting IgA rheumatoid factor antibodies in human serum. The device utilizes an enzyme-linked immunosorbent assay (ELISA) method. It is designed for use on the Hycor Hy. Tec Automated EIA instrument. Healthcare professionals in clinical laboratory settings use the assay results as one component of a multi-factorial diagnostic regime to aid in the diagnosis of rheumatoid arthritis. The output provides semi-quantitative levels of autoantibodies, which clinicians interpret alongside other laboratory and clinical investigations to support a diagnosis.

Clinical Evidence

No clinical data provided in the document; the submission relies on the 510(k) regulatory pathway for substantial equivalence.

Technological Characteristics

Enzyme-linked immunosorbent assay (ELISA) for semi-quantitative detection of IgA antibodies. Designed for use on the Hycor Hy. Tec Automated EIA instrument. In vitro diagnostic reagent kit.

Indications for Use

Indicated for semi-quantitative determination of IgA rheumatoid factor (RF) antibodies in human serum as an aid in the diagnosis of rheumatoid arthritis (RA). For professional in vitro diagnostic use.

Regulatory Classification

Identification

A rheumatoid factor immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the rheumatoid factor (antibodies to immunoglobulins) in serum, other body fluids, and tissues. Measurement of rheumatoid factor may aid in the diagnosis of rheumatoid arthritis.

Dear Ms. Knight:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic OS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition. FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
