"Autoimmune disease" is the generic term for a number of clinical conditions in which antibodies, generated by the patient's immune system, attack the body's own cells and tissues.

The unique line of EliA™ and Varelisa® autoimmune assays from Phadia AB incorporates the highest quality antigens. These antigens are produced primarily through recombinant DNA technology or by affinity purification from human and nonhuman tissues, resulting in a new generation of assays that produce accurate results. These standardized, easy-to-use enzyme-linked immunosorbent assay (ELISA) test kits are available to U.S. diagnostic laboratories for screening and confirmation testing.
