THE PROBLEM OF SPECIFICITY IN SEROLOGIC DETERMINATION OF HUMAN CHORIONIC GONADOTROPHIN

Abstract
Rabbit antisera, prepared against a commercial, highly purified preparation of human chorionic gonadotrophin, have been examined with regard to their serologic specificity. Analyses were carried out using procedures of immunodiffusion and complement fixation. Heterogeneity of the immune system is confirmed, and the distribution and serological relationship of unspecific antigens in urine and serum examined. The effect of various methods on the elimination of unspecific antibodies is shown.
