Multiple tests in the diagnosis of multiple sclerosis.

Visual evoked potentials (VEPs), somatosensory evoked potentials (SEPs), E-UFA test and CSF isoelectrofocusing (IEF) were applied to 42 multiple sclerosis patients. VEPs were abnormal in 29 cases. SEPs in 31 cases, E-UFA in 30 cases, CSF IEF in 38 cases. At least two tests were abnormal in 41 out of 42 patients; 16 cases revealed pathological responses in three tests (38,1%), 15 in four of them (35,7%). The authors discuss the value of using several tests in the diagnosis of multiple sclerosis and emphasize their importance for the purpose of diagnostic classification.
