Intended Use:

Test for qualitative determination of Rheumatoid Factors (RF) by immune agglutination method.


Rheumatoid factors are a group of antibodies directed to determinants in the Fc portion of the immunoglobulin G molecule. Although rheumatoid factors are found in a number of rheumatoid disorders, such as systemic lupus erythematosus (SLE) and Sjogren’s syndrome, as well as in nonrheumatic conditions, its central role in clinic lies its utility as an aid in the diagnosis of rheumatoid arthritis (RA). A study of the ‘American College of Rheumatology’, shows that the 80.4% RA patients were RF positive.
