The SSA-52 (Ro52) (ENA) Antibody, IgG is an important biomarker commonly tested to help diagnose autoimmune conditions, particularly Sjögren’s syndrome and systemic lupus erythematosus (SLE). This antibody targets Ro52, a protein involved in cellular stress responses, and its presence can indicate immune system activity against the body’s own tissues. Elevated levels of SSA-52 (Ro52) antibodies are often associated with systemic and organ-specific autoimmune diseases, such as mixed connective tissue disease (MCTD), polymyositis, or certain types of interstitial lung disease. Testing for this antibody is frequently part of an Extractable Nuclear Antigen (ENA) panel, which aids in identifying specific autoimmune conditions based on the antibody profile. Understanding the presence of SSA-52 (Ro52) antibodies in conjunction with symptoms and other biomarkers can guide accurate diagnosis and treatment.
