title: Heterophilic antibodies against rabbit serum causing falsely elevated gonadotropin levels.
abstract: Two cases are presented in which previously acquired antibodies against rabbits in the patient's serum caused falsely elevated hormonal levels in radio-immuno assays (RIA) based on rabbit antibodies to follicle-stimulating hormone (FSH) and human chorionic gonadotropin (hCG). The erroneous results led to unnecessary operative intervention and inconvenience for the patients.
