Service Providers for Anti-Sm
The Anti-Sm (Anti-Smith) test detects antibodies against Smith antigens, which are proteins found in the cell nucleus. These antibodies are highly specific to systemic lupus erythematosus (SLE), an autoimmune disease where the immune system attacks healthy tissues. A positive Anti-Sm test is considered a key marker for SLE, particularly in patients who present with symptoms like joint pain, skin rashes, and kidney issues. The test is performed using a blood sample, and the risks are minimal, typically involving slight discomfort during the blood draw. Elevated Anti-Sm levels are instrumental in diagnosing SLE.
