Description: Aids in the diagnosis of Sjögren syndrome (especially with inflammation of blood vessels) and lupus patients with Sjögren overlap syndrome. SS-A(Ro) is found in 60% to 70% of patients with Sjögren syndrome and 30% to 40% of patients with SLE. SS-B(La) is found in 50% to 60% of Sjögren syndrome and 10% to 15% of SLE. Anti-SS-A and anti-SS-B are found in virtually all children with neonatal lupus. Patients with SS-A may also have antibodies to cardiolipin, lupus anticoagulant, and clinical thromboses. This has been termed antiphospholipid antibody syndrome.
