Autoantibody Testing in Neuromuscular Disorders

Abstract

Autoantibodies are present in many autoimmune disorders, including diseases impacting the peripheral nerve, neuromuscular junction, and muscle. Some of these autoantibodies play a vital role in pathogenesis, whereas others are unlikely to be directly pathogenic, but may be useful biomarkers. The identification of autoantibodies is valuable in diagnosis, as well as in establishing a treatment plan in antibody-mediated neuromuscular disorders. This review briefly summarizes antibody, autoantibody, and methods of autoantibody testing for clinicians who treat patients with neuromuscular disorders.
