[Visual evoked potentials and the E-UFA test. Laboratory contribution to the diagnosis of multiple sclerosis].
Visual evoked potentials (VEPs) and electrophoretic mobility test of erythrocytes (E-UFA test) were compared in 50 multiple sclerosis (M.S.) patients as diagnostic tests. Abnormal VEPs were recorded in 35 patients. E-UFA test was found positive in 31 cases. With respect to Mc Alpine diagnostic criteria, 26 out of 33 definite M.S., 6 out of 9 probable M.S. and 3 out of 8 possible M.S. cases had abnormal VEPs. A positive response in E-UFA test was observed rispectively in 16, 8, 7 patients. Complessively 48 cases (96%) had an abnormal response to the one and/or to the other of the two tests, which apper complementar in early diagnosis of M.S.
