ENA Screen 6 ELISA

Enzyme immunoassay qualitatively screen human serum against RNP, Sm, SS-A/Ro, SS-B/La, Scl-70 and Jo-1 IgG antibodies. Circulating autoantibodies against various intracellular antigens are characteristic of systemic, autoimmune-mediated rheumatic diseases. These diseases include systemic lupus erythematosus (SLE), mixed connective tissue disease (MCTD), Sjögren’s syndrome (SS), progressive systemic sclerosis (PSS, scleroderma), rheumatoid arthritis (RA) and multiple Myositis (PM). Usually, these diseases can be diagnosed by measuring their related antibodies.
