Initial evaluation of patients aged 20 or older with symptoms and signs of acquired myasthenia gravis (MG)
Bone marrow transplant recipients with suspected graft-versus-host disease, particularly if weakness has appeared
Confirming that a recently acquired neurological disorder has an autoimmune basis (eg, MG)
Providing a quantitative baseline for future comparisons in monitoring a patient's clinical course and the response to immunomodulatory treatment
