Kappa free light chains index in the differential diagnosis of Multiple Sclerosis from Neuromyelitis optica spectrum disorders and other immune-mediated central nervous system disorders

摘要

The K free light chains index (K-FLC index) has been proposed as an alternative test for intrathecal immunoglobulin synthesis in MS diagnosis. Aim of the study was to assess the accuracy of the K-FLC index in differentiating MS from other immune-mediated CNS disorders and NMOSD.
