Early diagnosis and differentiation of Neuromyelitis optica (NMO) spectrum disorders are critically important to assure the most appropriate early treatment, making assays that are both highly sensitive and specific essential. Mayo Clinic studies, involving thousands of patients, have found the new cell-based aquaporin-4 (AQP4) antibody assay to be more sensitive and specific than enzyme-linked immunosorbent assay (ELISA) methods. The improved sensitivity and specificity of this test offered by Mayo Medical Laboratories will assist clinicians in distinguishing early stage NMO spectrum disorders from multiple sclerosis.
