Jo-1 Antibody Test

The Jo-1 Antibody Test measures antibodies that target histidyl-tRNA synthetase, often associated with autoimmune myositis and interstitial lung disease. This marker helps reveal autoimmune-related muscle inflammation, chronic lung symptoms, and joint pain. Results provide insights into underlying immune activity, assisting providers in diagnosis, treatment planning, and ongoing disease management for connective tissue disorders.
