ANA Profile Blot

The ANA Profile Blot is a diagnostic blood test used to detect antinuclear antibodies (ANAs) in the bloodstream. ANAs are autoantibodies that target the body’s own cells and tissues, and their presence can indicate autoimmune disorders, such as lupus, rheumatoid arthritis, scleroderma. The Western blot technique used in this test helps to identify specific ANA patterns, which can further help in diagnosing these conditions. The ANA Profile Blot is more sensitive and specific than basic ANA screening tests, providing a clearer understanding of which autoimmune disease may be present, based on the type of antibody detected and its reactivity to various nuclear antigens. It plays a crucial role in the diagnosis and management of autoimmune diseases.
