Anti-Synthetase Profile
Use
The Anti-Synthetase Profile is used to detect antibodies associated with anti-synthetase syndrome, an autoimmune disease that can lead to interstitial lung disease (ILD), non-erosive arthritis, myositis, Raynaud’s phenomenon, unexplained fever, and/or mechanic’s hands. By identifying the presence of specific antibodies such as Anti-Jo-1, PL-7, PL-12, EJ, and OJ, this profile assists in diagnosing and managing autoimmune conditions.
