title: The relation of serum immunoglobulin A and delayed hypersensitivity skin tests to serum immunoglobulin E levels.
abstract: Serum IgA and IgE levels were obtained in 706 patients, 294 of whom were also tested for cutaneous delayed hypersensitivity. The results do not support the concept that a deficiency of serum IgA or of T lymphocyte function underlies the elevated serum IgE levels observed in a majority of allergic patients.
