CLINICAL ASSOCIATIONS

Mitogen’s Interstitial Lung Disease (ILD) Antibody Profile is an autoimmune diagnostic test that detects antibodies directed to Jo-1 (histidyl t-RNA synthetase) and other synthetase targets (PL7, PL-12, OJ, EJ); as well as Ku, Scl-70- (topoisomerase I), CENP-B, Scl-34 (fibrillarin), Th/To, RNA polymerase, U1-RNP, Ro52/TRIM21, Mi-2, MDA-5. Autoantibodies directed to these targets have been associated with the presence or risk of developing interstitial lung disease (ILD), or a risk of developing a systemic rheumatic disease.
