The Randox Rheumatoid Factor Latex-Enhanced Immunoturbidimetric Test Kit is an invitro diagnostic reagent for the quantitative determination of rheumatoid factors (RF) in human serum. This test kit may be used to facilitate the detection and diagnosis of Rheumatoid Arthritis. RF have also been observed in the serum of patients with systemic lupus erythematosus, hepatitis, liver cirrhosis and syphilis. However, in these conditions the RF titre is much lower than in rheumatoid arthritis.
This test kit must be used by suitably qualified personnel under appropriate laboratory conditions.
RF calibrator and RF positive control are for use in the calibration and quality control of RF latex-enhanced immunoturbidimetric assays.

The provided document is an FDA 510(k) clearance letter for the Rheumatoid Factor Latex-Enhanced Immunoturbidimetric Test Kit. This letter approves the device for marketing based on its substantial equivalence to a predicate device. It does not contain the detailed study data, acceptance criteria, or performance metrics in a format that allows me to populate the requested table directly.
The FDA 510(k) summary (which is a separate document often submitted with the clearance letter, but not provided here) typically describes the performance data and the comparison to the predicate device. Without that specific summary or the full study report, I cannot provide the detailed information requested regarding acceptance criteria, reported performance, sample sizes, ground truth methodology, or expert qualifications.
Therefore, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets them using only the provided text. The provided text is a regulatory clearance document, not a scientific study report.
§ 866.5775 Rheumatoid factor immunological test system.
(a)
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.(b)
Classification. Class II (performance standards).
