AI/ML Overview

This document is a 510(k) Premarket Notification from the FDA regarding the ImmuLisa Enhanced™ RF IgA Antibody ELISA, ImmuLisa Enhanced™ RF IgG Antibody ELISA, ImmuLisa Enhanced™ RF IgM Antibody ELISA, and ImmuLisa Enhanced™ RF IgA/IgG/IgM Antibody ELISA. It doesn't contain information about acceptance criteria or a study that proves the device meets specific performance metrics.

The document primarily states that the FDA has reviewed the submission and determined that the device is substantially equivalent to legally marketed predicate devices. It outlines regulatory information such as:

Trade/Device Name: ImmuLisa Enhanced™ RF IgA Antibody ELISA, ImmuLisa Enhanced™ RF IgG Antibody ELISA, ImmuLisa Enhanced™ RF IgM Antibody ELISA, ImmuLisa Enhanced™ RF IgA/IgG/IgM Antibody ELISA
Regulation Number: 21 CFR 866.5775
Regulation Name: Rheumatoid factor immunological test system
Regulatory Class: Class II
Product Code: DHR
Indications for Use: Enzyme linked immunoassay (ELISA) for the qualitative or semi-quantitative detection of Rheumatoid Factor IgA, IgG, and/or IgM antibodies in human serum to aid in the diagnosis of rheumatoid arthritis (RA) in conjunction with other laboratory tests and clinical findings.
Type of Use: Prescription Use

Therefore, I cannot provide the requested information about acceptance criteria, device performance, study details (sample sizes, data provenance, ground truth establishment, expert qualifications, adjudication methods), MRMC studies, or standalone algorithm performance, as these details are not present in the provided text.

Dear Mr. Lawson:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and 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) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Actinclude requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the
