Serum immunoglobulin E (IgE) concentrations in 60 children with bronchial asthma, 20 healthy children and 20 healthy adults were determined by both radioimmunoassay and single radial immunodiffusion methods, and the relation between serum IgE and clinical spectrum of asthma was analysed. The mean serum IgE in asthmatic children was higher than that in healthy controls (p<0.03). The Patients with allergic type of asthma, positive skin tests and recent attack had higher serum IgE than the Patients without those characteristics had. The patients receiving longer duration of hyposensitization tended to have lower, though not statistically significant, serum IgE.
