SM (SMITH) ANTIBODY, IGG

The SM (Smith) Antibody, IgG test detects the presence of IgG antibodies against the Smith antigen, a specific marker for the autoimmune disorder Lupus (Systemic Lupus Erythematosus (SLE). This test is prescribed by rheumatologists or internal medicine physicians to confirm an autoimmune response, especially when lupus is suspected. Since SM antibodies are highly specific to SLE, this test supports accurate diagnosis and guides further evaluation and treatment.
