the serum of 20 apparently hypergonadotropic and/or hyperprolactinemic patients ( 14 females , 6 males , ages 13-75 years ) without evidence of neoplasia or pituitary adenomas was found to contain a large amount of molecular material ( mw ca . 100,000 ) resulting in factitiously elevated levels of peptide hormones when measured by double-antibody radioimmunoassay with a long second incubation time .
