The Anti-SSA/Ro test is a blood test used to identify autoantibodies associated with specific diseases such as Sjögren’s syndrome and systemic lupus erythematosus (SLE). These autoantibodies, which include two subtypes Ro/SSA-52 and Ro/SSA-60, often play a role in the diagnosis and monitoring of these diseases. Their presence may be associated with symptoms such as dry eyes and mouth (in Sjögren’s syndrome) or photosensitivity and skin complications in lupus. Additionally, these autoantibodies are especially important in pregnant women because they are linked to the risk of antibody transfer to the fetus, leading to complications such as neonatal lupus or congenital heart block. Common diagnostic methods include ELISA or immunoassay, but positive results should be interpreted alongside clinical symptoms and other tests, as they can sometimes be detected in healthy individuals without active disease.
