PROVIDER INITIATED TEST - The Sm (Smith) Antibodies test measures antibodies directed against Smith (Sm) antigens, which are components of small nuclear ribonucleoproteins involved in RNA processing. These antibodies are highly specific for systemic lupus erythematosus (SLE).
This test is typically ordered as part of an ANA component or autoimmune evaluation when lupus is suspected. While Sm antibodies are not present in all individuals with lupus, a positive result strongly supports an SLE diagnosis. Results are interpreted alongside other autoimmune markers and clinical findings.
