This test detects antibodies most commonly associated with Sjögren’s syndrome, and sometimes found in patients with systemic lupus erythematosus (SLE).

  • Diagnostic Use: Anti-SS-B often appears together with Anti-SS-A and strengthens the diagnosis of Sjögren’s syndrome, particularly in patients with dry eyes and dry mouth.
  • Clinical Relevance: While Anti-SS-B alone is less common, its presence provides additional evidence of autoimmune activity and helps refine the diagnosis.
  • Pregnancy Considerations: Like Anti-SS-A, Anti-SS-B antibodies can be relevant in pregnancy, as they may be associated with neonatal lupus or congenital heart block in infants.

Detecting Anti-SS-B antibodies supports early identification and more precise management of autoimmune conditions.
