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 eruthematosus, 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.
