Anti-SSA (Ro)

Anti-SSA (Ro) antibodies (often tested together with Anti-SSB/La) are autoantibodies commonly found in Sjögren's syndrome and Systemic Lupus Erythematosus (SLE). They are associated with photosensitivity, specific skin rashes (subacute cutaneous lupus), and risk of neonatal lupus (congenital heart block) if present during pregnancy.
