title: Use of RAST technique in wasp sting hypersensitivity. Cross-reactions between various insect antigens are specially considered.
abstract: Clinical hypersensitivity to wasp stings was found to be fairly well correlated with the presence of serum IgE-antibodies against yellow jacket venom as detected by the RAST technique. Such antibodies were never found in a control group of non-allergic blood donors, but they were detected in a surprisingly large proportion of patients with bee sting allergy without known allergic reactions to wasps. Studies using RAST inhibition technique failed to prove cross-reactions between bee and wasp venoms. Considerably better results were obtained when venom antigens instead of whole body antigens were used in the RAST. RAST inhibition studies suggested that IgE-antibodies detected with RAST using whole body antigen are directed against bee venom constituents in the whole body extract.
