RESUMO

Serum immunoglobulin E concentration was studied in normal children and adults, in 25 patients with isolated IgA deficiency, and in 44 patients with ataxia telangiectasia using a double antibody radioimmunoassay. The geometric mean IgE level of the normal adult population studied was 105 ng/ml, with a broad 95% interval (5-2045 ng/ml). Individuals with concentrations less than 15 ng/ml were considered to be IgE deficient. IgE deficiency, defined in this way, was observed in 7 of 73 normal adults and was not found to be associated with respiratory tract disease.
