What is it indicated for?
The presence of autoantibodies to a number of nuclear constituents has proven to be useful in the diagnosis of various connective tissue diseases. Although the exact etiology of autoimmune diseases is unknown, and the specific role played by autoantibodies in the onset of various autoimmune connective tissue diseases is obscure, the association and frequency of detection of these antibodies may play a key role in the diagnostic work-up of patients with suspected connective tissue diseases.
The Sm ELISA test system is intended for the manual or automated analysis of human serum for the presence or absence of IgG antibodies Sm.
