title: [Demonstration of specific serum IgG with an "in vitro" radioimmunoassay (RAST IgG) (author's transl)].
abstract: By using discs coated with allergens (RAST, Pharmacia) anti-human gammaglobulin goat antibodies, we could demonstrate specific IgG on sera whose IgE had been destroyed by heating at 56 degrees C for 4 hours. A detailed protocol is given. Preliminary results demonstrate absence of specific IgG in untreated patients with pollen allergy, and conversely presence of these IgG in patients treated with immunotherapy against pollens; most patients with epithelia, food and/or mould allergies had specific IgG prior to immunotherapy.
