Determination of immunoglobulin E concentrations in the sera of patients with chronic brucellosis

: The data on the level of IgE in the sera of 41 patients with chronic brucellosis are presented. The IgE content in the sera was determined by the radioimmunoassay. A 3- to 17-fold increase in the concentration of total IgE was revealed. The increased concentration of IgE correlated with the results of Burnet' allergic test and the indirect leukocytolysis test.
