title: [Usefulness of the immunoglobulin-albumin ratio compared to electrophoresis in the diagnosis of multiple sclerosis].
abstract: The results obtained with gel electrophoresis on CSF samples of multiple sclerosis patients are compared with measurements of CSF IgG indexes (IgG/alb and IgG/total protein). The correlation between these parameters is good, provided the upper normal limit of the IgG/alb index is over 35% and an "overlapping" zone between 21 and 35% is introduced where the IgG/alb index has not the same diagnostic value.
