Skeletal Muscle Antibodies Test - Skeletal Muscle Antibodies (ABS) Test

This analysis measures the presence and quantity of autoantibodies directed against components of skeletal muscle cells in the blood. These antibodies are often detected using indirect immunoassay (IIF) on muscle tissue slices (typically from a monkey or mouse). The presence of these antibodies is associated with autoimmune diseases affecting muscles, and the fluorescence pattern helps identify the type of muscle targeted (e.g., muscle fibers or blood vessels).
