[Immunoenzyme method of determining the specific cerebral alpha 2-globulin in the blood serum of children with Tourette syndrome].

Using highly purified antibodies to cerebral alpha 2-globulin (alpha 2-B) the authors have developed a procedure for enzyme immunoassay of this antigen in biological fluids. Blood sera of 15 children with Tourette's syndrome were examined by this method. The levels of alpha 2-B and the clinical picture of the disease were found to correlate, which makes it possible to use an assay of alpha 2-B as a laboratory test for the diagnosis of Tourette's syndrome and for the monitoring of its treatment.
