Autoantibody Profiles of Myasthenia Gravis, Thymoma, and Lambert-Eaton Myasthenic Syndrome

May 2012

An algorithmic testing approach using established autoantibody profiles can assist the clinician in the diagnosis of myasthenia gravis and Lambert-Eaton myasthenic syndrome. Dr. McKeon will review the serological diagnostic algorithms for myasthenia gravis (MG), thymoma, and Lambert-Eaton myasthenic syndrome (LES). He will define the clinical aspects of each disorder and describe diagnostic laboratory testing recommendations.
