[IgG determination in the cerebrospinal fluid--correlation of these results with other cerebrospinal fluid values].
IgG determined by means of quantitative radial immunodiffusion in the cerebrospinal fluid of 225 neurological patients correlates in a statistically significant manner (p less than 0.001) with the gamma-globulin determined by the acetate foil electrophoresis. The indication of the IgG as a percentage of the total protein (limiting value of 10 per cent) is suitable for an orientating assessment in the diagnosis of inflammatory-immunoreactive diseases of the central nervous system. The IgG-values exceeding 10 per cent of the total protein correlate in 260 fluids examined in the respect with the percental value of the lymphocyte content which also lies above the reference range (p less than 0.001). For the assessment of the presence of a barrier disturbance, a comparison with the serum values should be carried out, either in the form of the frequently used fluid/serum quotients of the immunglobulin or the electrophoretically separated protein fraction.
