EUGENE Rheumatoid Factor (RF) Rapid Test Kit is a rapid chromatographic immunoassay for the qualitative detection of RF in serum or plasma. It is used as an aid in the diagnosis of rheumatoid arthritis.
Rheumatoid factor (RF) is an autoantibodymost relevant in rheumatoid arthritis. It is an antibody against the Fc portion of IgG, which is itself an antibody. RF is often evaluated in patients suspected of having any form of arthritis even though positive results can be due to other causes. It is part of the usual disease criteria of rheumatoid arthritis, and RF may serve as one of several serological markers for autoimmunity unrelated to rheumatoid arthritis [4]. High levels of rheumatoid factor (generally above 20 IU/mL) occur in rheumatoid arthritis (present in 80%) and Sjögren's syndrome (present in 70%)[5,6]. Rheumatoid Factor (RF) Rapid Test Kit utilizes RF antibodies to specifically detect the presence of RF in human serum/plasma without the use of an instrument.
INTERPRETATION OF RESULTS Negative: Only one colored band appears on the control region. No apparent band on the test region. Positive: In addition to a pink colored control band, a distinct Pink colored band will also appear in the test region. Invalid: A total absence of color in either regions or only one color band appears on the test region indicate procedure error and/or the test reagent has deteriorated.
