PROVIDER INITIATED TEST - The SS-B (La) Antibodies test measures antibodies directed against the La (SS-B) antigen, a protein found in the cell nucleus. These antibodies are most commonly associated with Sjögren’s syndrome and may also be present in other autoimmune conditions such as systemic lupus erythematosus (SLE).
This test is typically ordered as part of an ANA component or autoimmune evaluation when symptoms such as dry eyes, dry mouth, joint pain, fatigue, or unexplained inflammation are present. SS-B antibodies are often interpreted alongside SS-A (Ro) antibodies and other autoimmune markers to support diagnosis and disease assessment.
