Uses: The results of the RF IgG 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™ I Rheumatoid Factor IgG ELISA is an in vitro diagnostic assay for detecting IgG 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. The assay provides semi-quantitative results that serve as one indicator in a multi-factorial diagnostic regime for rheumatoid arthritis. It is intended for use by clinical laboratory professionals to support clinical and laboratory investigations. The output assists physicians in the diagnostic process for RA. ## Technological Characteristics Enzyme-linked immunosorbent assay (ELISA) for IgG rheumatoid factor detection. Designed for use on the Hycor Hy•Tec Automated EIA instrument. In vitro diagnostic device. ## Regulatory 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. ## Reference Devices - Hycor Hy•Tec Automated EIA instrument ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Pentlands Science Park Bush Loan, Penicuik Midlothian EH26 0PL Scotland, United Kingdom Re: K993304 > Trade Name: Autostat™I Rheumatoid Factor IgG ELISA Regulatory Class: II Product Code: DHR Dated: September 30, 1999 Received: October 4, 1999 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 QS 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. {1}------------------------------------------------ Page 2 Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA-88), this device may require a CLIA complexity categorization. To determine if it does, you should contact the Centers for Disease Control and Prevention (CDC) at (770)488-7655. This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639.
