Interpretive Data
May include disease information, patient result explanation, recommendations, or details of testing.
SSB (La) antibody is seen in 50-60% of Sjögren syndrome cases and is specific if it is the only ENA antibody present. Fifteen-25% of patients with systemic lupus erythematosus (SLE) and 5-10% of patients with progressive systemic sclerosis (PSS) also have this antibody.
