Immunoglobulin M (IgM) antibodies directed against IgG antibodies (rheumatoid factor [RF]) are known to occur often in patients with syphilis and to interfere with serological tests measuring specific antibodies of the IgM class. In this study we examined the occurrence and specificity of the RF and demonstrated a simple method to detect and eliminate ...

Pseudoglobulin Rheumatoid Factors
The Journal of Immunology, 1965Summary Although the rheumatoid factors (RF) are believed to be relatively insoluble in dilute salt solutions, considerable RF activity in pseudoglobulin fractions was encountered on examination of certain sera of persons having rheumatoid arthritis.

We have studied the distribution of rheumatoid factor isotypes amongst patients with loiasis with and without accompanying glomerulonephritis to determine the possible role of rheumatoid factor antiglobulins in this disease. Our findings indicate an increase in both immunoglobulin (Ig) G and IgM rheumatoid factor isotypes in patients with filariasis ...

Abstract Rheumatoid factors (RF) associated with arthritic joint erosion are only seen transiently, if at all, in nondiseased individuals. Therefore, a tolerance mechanism must exist that prevents pathologic RF B cells from expressing Abs.

Rheumatoid factors (RFs) are autoantibodies with specificity against constant regions of the heavy chain in the IgG Fc fragment. RFs are detected in several systemic autoimmune conditions and in infectious diseases and can be present in healthy subjects.

Determination of Rheumatoid Factors by ELISA
2018IgM and IgA autoantibodies binding to IgG are called rheumatoid factors (RFs) and occur with high frequency in rheumatoid arthritis (RA) and with lower frequency in other autoimmune diseases. RFs have diagnostic and prognostic value in RA, but they also have a high potential to cause false positive reactions in other immunoassays, especially sandwich ...
