Complement consumption in eggwhite and fish sensitivity.
A case of eggwhite allergy and a case of fish allergy, where complement-fixation by thermostable IgG-class antibody was positive at extremely high antigen dilutions are described. The antibody in eggwhite allergy was of the precipitating variety and the C-fixation phenomenon was not related to the presence or absence of IgE antibody.
