[Assessment of prealbumin in cerebrospinal fluid].

The paper describes statistical relationship between prealbumin and total protein in lumbal CSF of a control group and a total group of patients with neurological diseases. The equations of the regression lines and the boundary lines of the distribution areas did not significantly differ between both groups. Therefore, prealbumin seems to be not qualified for differential diagnosis. On the other hand, its application to characterize functional states of blood-brain-CSF barrier systems is discussed.
