  • Abstract

To determine the serum concentrations of human chorionic gonadotropin (hCG), its free β-subunit (hCG β), and the free α-subunit (free a) common to all human glycoprotein hormones under physiological and pathological conditions, we developed monoclonal antibody-based immunoenzymometric assays. Free α-subunit was detected in the sera of all healthy individuals of both sexes ; hCG was measurable in sera of 54% of the men, and 46% were positive for free hCG β ; in nonpregnant women, 69.5% were positive for hCG, 68.4 % for the free β-subunit. Pathological conditions, i. e., hCG-producing tumors, were studied in vitro and in vivo.
