title: [False reactions in hydatic serology in order to improve its value (author's transl)].
abstract: We have studied false reactions in hydatic serology in order to improve its value. We have found false positive reactions in two cases of tumor (hepatic sclerocholangiomatosis and pleural mesothelioma) and among children showing cor's milk protein intolerance when serum is tested with an antigen extracted from ox's lung. As for false negative reactions, they are scarcely due to circulating antigens. We have found, for 34 falsely negative serums, IgG, IgM and above all IgE levels lower than the levels of patients showing a positive serology.
